GENERAL DESCRIPTION
FEATURES
Detect Voltage Range Hysteresis Range : 1.6V ~ 5.0V, +2% (100mV increments) : VDF x 5%, TYP. (XC6101~XC6107) VDF x 0.1%, TYP. (XC6111~XC6117) : 1.0V ~ 6.0V
The XC6101~XC6107, XC6111~XC6117 series are groups of high-precision, low current consumption voltage detectors with manual reset input function and watchdog functions incorporating CMOS process technology. The series consist of a reference voltage source, delay circuit, comparator, and output driver. With the built-in delay circuit, the XC6101 ~ XC6107, XC6111 ~ XC6117 series' ICs do not require any external components to output signals with release delay time. Moreover, with the manual reset function, reset can be asserted at any time. The ICs produce two types of output; VDFL (low when detected) and VDFH (high when detected). With the XC6101 ~ XC6105, XC6111 ~ XC6115 series' ICs, the WD pin can be left open if the watchdog function is not used. Whenever the watchdog pin is opened, the internal counter clears before the watchdog timeout occurs. Since the manual reset pin is internally pulled up to the VIN pin voltage level, the ICs can be used with the manual reset pin left unconnected if the pin is unused. The detect voltages are internally fixed 1.6V ~ 5.0V in increments of 100mV, using laser trimming technology. Six watchdog timeout period settings are available in a range from 6.25msec to 1.6sec. Seven release delay time 1 are available in a range from 3.13msec to 1.6sec.
Operating Voltage Range Detect Voltage Temperature Characteristics : +100ppm/OC (TYP.) Output Configuration : N-channel open drain, CMOS Watchdog Pin : Watchdog input If watchdog input maintains `H' or `L' within the watchdog timeout period, a reset signal is output to the RESET output pin Manual Reset Pin : When driven `H' to `L' level signal, the MRB pin voltage asserts forced reset on the output pin. Release Delay Time : 1.6sec, 400msec, 200msec, 100msec, 50msec, 25msec, 3.13msec (TYP.) can be selectable. Watchdog Timeout Period : 1.6sec, 400msec, 200msec, 100msec, 50msec, 6.25msec (TYP.) can be selectable.

XC6101~XC6107, XC6111~XC6117 Series
OPERATIONAL EXPLANATION
The XC6101~XC6107, XC6111~XC6117 series compare, using the error amplifier, the voltage of the internal voltage reference source with the voltage divided by R1, R2 and R3 connected to the VIN pin. The resulting output signal from the error amplifier activates the watchdog logic, manual reset logic, delay circuit and the output driver. When the VIN pin voltage gradually falls and finally reaches the detect voltage, the RESETB pin output goes from high to low in the case of the VDFL type ICs, and the RESET pin output goes from low to high in the case of the VDFH type ICs. * VDFL (RESETB) type - output signal: Low when detected. The RESETB pin output goes from high to low whenever the VIN pin voltage falls below the detect voltage, or whenever the MRB pin is driven from high to low. The RESETB pin remains low for the release delay time (TDR) after the VIN pin voltage reaches the release voltage. If neither rising nor falling signals are applied to the WD pin within the watchdog timeout period, the RESETB pin output remains low for the release delay time (TDR), and thereafter the RESET pin outputs high level signal. * VDFH (RESET) type - output signal: High when detected. The RESET pin output goes from low to high whenever the VIN pin voltage falls below the detect voltage, or whenever the MRB pin is driven from high to low. The RESET pin remains high for the release delay time (TDR) after the VIN pin voltage reaches the release voltage. If neither rising nor falling signals are applied to the WD pin within the watchdog timeout period, the VOUT pin output remains high for the release delay time (TDR), and thereafter the RESET pin outputs low level signal. When the internal comparator output is high, the NMOS transistor connected in parallel to R3 is turned ON, activating the hysteresis circuit. The difference between the release and detect voltages represents the hysteresis range, as shown by the following calculations: VDF (detect voltage) = (R1+R2+R3) x Vref(R2+R3) VDR (release voltage) = (R1+R2) x Vref(R2) VHYS (hysteresis range)=VDR-VDF (V) VDR > VDF * Detect voltage (VDF) includes conditions of both VDFL (low when detected) and VDFH (high when detected). * Please refer to the block diagrams for R1, R2, R3 and Vref. Hysteresis range is selectable from VDF x 0.05V (XC6101~XC6107) or VDF x 0.001V (XC6111~XC6117). The XC6101~XC6107, XC6111~XC6117 series use a watchdog timer to detect malfunction or "runaway" of the microprocessor. If neither rising nor falling signals are applied from the microprocessor within the watchdog timeout period, the RESETB/RESET pin output maintains the detection state for the release delay time (TDR), and thereafter the RESET/RESETB pin output returns to the release state (Please refer to the FUNCTION CHART). The timer in the watchdog is then restarted. Six watchdog timeout period settings are available in 1.6sec, 400msec, 200msec, 100msec, 50msec, 6.25msec. Using the MRB pin input, the RESET/RESETB pin signal can be forced to the detection state. When the MRB pin is driven from high to low, the RESETB pin output goes from high to low in the case of the VDFL type ICs, and the RESET pin output goes from low to high in the case of the VDFH type. Even after the MRB pin is driven back high, the RESET/RESETB pin output maintains the detection state for the release delay time (TDR). Since the MRB pin is internally pulled up to the VIN pin voltage level, leave the MRB pin open if unused (Please refer to the FUNCTION CHART). A diode, which is an input protection element, is connected between the MRB pin and VIN pin. Therefore, if the MRB pin is applied voltage that exceeds VIN, the current will flow to VIN through the diode. Please use this IC within the stated maximum ratings (VSS -0.3 ~ VIN +0.3) on the MRB pin. Release delay time (TDR) is the time that elapses from when the VIN pin reaches the release voltage, or when the watchdog timeout period expires with no rising signal applied to the WD pin, until the RESET/RESETB pin output is released from the detection state. Seven release delay time (TDR) watchdog timeout period settings are available in 1.6sec, 400msec, 200msec, 100msec, 50msec, 25msec, 3.13msec. Detect Delay Time (TDF) is the time that elapses from when the VIN pin voltage falls to the detect voltage until the RESET/ RESETB pin output goes into the detection state.

XC6101~XC6107, XC6111~XC6117 Series
NOTES ON USE
1. Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent damage to the device. 2. When a resistor is connected between the VIN pin and the input, the VIN voltage drops while the IC is operating and a malfunction may occur as a result of the IC's through current. For the CMOS output products, the VIN voltage drops while the IC is operating and malfunction may occur as a result of the IC's output current. Please be careful with using the XC6111~XC6117 series (without hysteresis). 3. In order to stabilize the IC's operations, please ensure that the VIN pin's input frequency's rise and fall times are more than 1 sec/V. 4. Noise at the power supply may cause a malfunction of the watchdog operation or the circuit. In such case, please strength the line between VIN and the GND pin and connect about 0.22F of a capacitor between the VIN pin and the GND pin. 5. Protecting against a malfunction while the watchdog time out period, an ignoring time (no reaction time) occurs to the rise and fall times. Referring to the figure below, the ignoring time (no reaction time) lasts for 900sec at maximum.
