General Description
The TC1037/TC1038/TC1039 are single, low-power comparators designed for low-power applications. These comparators are specifically designed for operation from a single supply. However, operation from dual supplies also is possible, and power supply current is independent of the magnitude of the power supply voltage. The TC1037/TC1038/TC1039 operate from two 1.5V alkaline cells down to VDD = 1.8V. Active supply current is 4A for the TC1037/TC1038 and 6A for the TC1039. Input and output swing of these devices is rail-to-rail. An active low shutdown input, SHDN, is available on the TC1038 and disables the comparator, placing its output in a high-impedance state. The TC1038 draws only 0.05A (typical) when the shutdown mode is active. An internally biased 1.20V bandgap reference is included in the TC1039. The reference is accurate to 2.0 percent tolerance. This reference is independent of the comparator in the TC1039. Temperature Range -40C to +85C -40C to +85C -40C to +85C Packaged in a 5-Pin SOT-23A (TC1037) or 6-Pin SOT-23A (TC1038/TC1039), these single comparators are ideal for applications requiring high integration, small size and low power.

3.0 DETAILED DESCRIPTION 4.0 TYPICAL APPLICATIONS
The TC1037/TC1038/TC1039 are a series of very low power, linear building block products targeted at low voltage, single supply applications. The TC1037/ TC1038/TC1039 minimum operating voltage is 1.8V and typical supply current is only 4A for the TC1037 and TC1038 (fully enabled) and 6A for the TC1039. The TC1037/TC1038/TC1039 family lends itself to a wide variety of applications, particularly in battery powered systems. It typically finds application in power management, processor supervisory and interface circuitry.
4.1 3.1 Comparator
The TC1037/8/9 contain one comparator. The comparator's input range extends beyond both supply voltages by 200mV and the outputs will swing to within several millivolts of the supplies depending on the load current being driven. The comparator exhibits a propagation delay and supply current which is largely independent of supply voltage. The low input bias current and offset voltage makes it suitable for high impedance precision applications. The TC1038 comparator is disabled during shutdown and has a high impedance output. 2. 3.
External Hysteresis (Comparator)
Hysteresis can be set externally with two resistors using positive feedback techniques (see Figure 4-1). The design procedure for setting external comparator hysteresis is as follows: 1. Choose the feedback resistor RC. Since the input bias current of the comparator is at most 100pA, the current through RC can be set to 100nA (i.e., 1000 times the input bias current) and retain excellent accuracy. The current through RC at the comparator's trip point is VR / RC where VR is a stable reference voltage. Determine the hysteresis voltage (VHY) between the upper and lower thresholds. Calculate RA as follows:

SHDN at VIL disables the comparator and reduces the supply current to less than 0.3A. The SHDN input cannot be allowed to float. When not used, connect it to VDD. The comparator's output is in a high impedance state when the TC1038 is disabled. The comparator's inputs can be driven from rail-to-rail by an external voltage when the TC1038 is disabled. No latchup will occur when the device is driven to its enabled state when SHDN is set to VIH.
Choose the rising threshold voltage for VSRC (VTHR). Calculate RB as follows:

A 2.0% tolerance, internally biased, 1.20V bandgap voltage reference is included in the TC1039. It has a push-pull output capable of sourcing and sinking at least 50A.

4.2 Precision Battery Monitor
Figure 4-2 is a precision battery low/battery dead monitoring circuit. Typically, the battery low output warns the user that a battery dead condition is imminent. Battery dead typically initiates a forced shutdown to prevent operation at low internal supply voltages (which can cause unstable system operation). The circuit in Figure 4-2 uses a TC1034, a TC1037 and a TC1039, and only six external resistors. AMP 1 is a simple buffer, while CMPTR1 and CMPTR2 provide precision voltage detection using VR as a reference. Resistors R2 and R4 set the detection threshold for BATT LOW, while resistors R1 and R3 set the detection threshold for BATT FAIL. The component values shown assert BATT LOW at 2.2V (typical) and BATT FAIL at 2.0V (typical). Total current consumed by this circuit is typically 16A at 3V. Resistors R5 and R6 provide hysteresis for comparators CMPTR1 and CMPTR2, respectively. The value of the timing capacitor C1 must be small enough to allow CMPTR1 to discharge C1 to a diode voltage before the feedback signal from CMPTR2 (through R10) switches CMPTR1 to its high state and allows C1 to start an exponential charge through R5. Proper circuit action depends upon rapidly discharging C1 through the voltage set by R6, R9 and D2 to a final voltage of a small diode drop. Two propagation delays after the voltage on C1 drops below the level on the non-inverting input of CMPTR2, the output of CMPTR1 switches to the positive rail and begins to charge C1 through R5. The time delay which sets the output pulse width results from C1 charging to the reference voltage set by R6, R9 and D2, plus four comparator propagation delays. When the voltage across C1 charges beyond the reference, the output pulse returns to ground and the input is again ready to accept a trigger signal.

32.768 kHz "Time Of Day Clock" Crystal Controlled Oscillator
A very stable oscillator driver can be designed by using a crystal resonator as the feedback element. Figure 4-3 shows a typical application circuit using this technique to develop a clock driver for a Time Of Day (TOD) clock chip. The value of RA and RB determine the DC voltage level at which the comparator trips - in this case onehalf of VDD. The RC time constant of RC and CA should be set several times greater than the crystal oscillator's period, which will ensure a 50% duty cycle by maintaining a DC voltage at the inverting comparator input equal to the absolute average of the output signal.
Microchip's linear building block comparators adapt well to oscillator applications for low frequencies (less than 100kHz). Figure 4-5 shows a symmetrical square wave generator using a minimum number of components. The output is set by the RC time constant of R4 and C1, and the total hysteresis of the loop is set by R1, R2 and R3. The maximum frequency of the oscillator is limited only by the large signal propagation delay of the comparator in addition to any capacitive loading at the output which degrades the slew rate. To analyze this circuit, assume that the output is initially high. For this to occur, the voltage at the inverting input must be less than the voltage at the non-inverting input. Therefore, capacitor C1 is discharged. The voltage at the non-inverting input (VH) is:
4.4
Non-Retriggerable One Shot Multivibrator
Using two comparators, a non-retriggerable one shot multivibrator can be designed using the circuit configuration of Figure 4-4. A key feature of this design is that the pulse width is independent of the magnitude of the supply voltage because the charging voltage and the intercept voltage are a fixed percentage of VDD. In addition, this one shot is capable of pulse width with as much as a 99% duty cycle and exhibits input lockout to ensure that the circuit will not re-trigger before the output pulse has completely timed out. The trigger level is the voltage required at the input to raise the voltage at node A higher than the voltage at node B, and is set by the resistive divider R4 and R10 and the impedance network composed of R1, R2 and R3. When the one shot has been triggered, the output of CMPTR2 is high, causing the reference voltage at the non-inverting input of CMPTR1 to go to V DD. This prevents any additional input pulses from disturbing the circuit until the output pulse has timed out.

Capacitor C1 will charge up through R4. When the voltage of the comparator's inverting input is equal to VH, the comparator output will switch. With the output at ground potential, the value at the non-inverting input terminal (V L) is reduced by the hysteresis network to a value given by: basically the same as described for the free-running oscillator. If the input control voltage is moved above or below one-half VDD, the duty cycle of the output square wave will be altered. This is because the addition of the control voltage at the input has now altered the trip points. The equations for these trip points are shown in Figure 4-6 (see VH and VL). Pulse width sensitivity to the input voltage variations can be increased by reducing the value of R6 from 10K and conversely, sensitivity will be reduced by increasing the value of R6. The values of R1 and C1 can be varied to produce the desired center frequency.
EQUATION 4-7:
VL V DD = ---------3
Using the same resistors as before, capacitor C1 must now discharge through R4 toward ground. The output will return to a high state when the voltage across the capacitor has discharged to a value equal to VL. The period of oscillation will be twice the time it takes for the RC circuit to charge up to one half its final value. The period can be calculated from:
