Edge737 Per-Pin Precision Measurement Unit
TEST AND MEASUREMENT PRODUCTS Description
The Edge737 is a precision measurement unit designed for automatic test equipment and instrumentation. Manufactured in a wide voltage CMOS process, it is a monolithic solution for a per pin PMU. The Edge737 supports two modes of operation: force current/measure voltage and force voltage/measure current. The Edge737 can force or measure voltage in the range of +7V to -5V. In addition, the Edge737 can force or measure a current of up to 40 mA over four distinct ranges: 40 mA, 1 mA, 100 A and 10 A. The Edge737 has an on board window comparator that provides three bits of information: DUT too high, DUT too low, and DUT fail. There is also a monitor function which provides a real time analog voltage signal proportional to either the DUT voltage or current. On board clamps prevent large transient spikes when changing operating mode or current range. Also, the PMU will survive a direct short over the legal voltage range. The Edge737 is designed to be a low power, low cost, small footprint solution to allow high pin count testers to support a PMU per pin.

TEST AND MEASUREMENT PRODUCTS Circuit Description
Circuit Overview The Edge737 is a parametric test and measurement unit that can : * Force Voltage / Measure Current * Force Current / Measure Voltage. The Edge737 can force or measure voltage over a +7V to -5V range, and force or measure current over four distinct ranges: * 40 mA * 1 mA * 100 A * 10 A. An on board window comparator provides three-bit measurement range classification. Also, a monitor passes a real time analog signal which tracks either the DUT's current or voltage performance. Control Inputs MODE SEL is a digital input which determines whether the PMU forces voltage or current, when it is not placed in a high impedance state by the HIZ input (see Table 1). Comparator Outputs The comparator outputs DUT GTL, DUT LTH, and PASS/FAIL* are open drain outputs. When active (logical 0), they will pull to ground. When disabled (logical 1 or DISABLE = 1), they require an external pull up resistor to a positive voltage to achieve a high state. Force / Sense FORCE is an analog output which either forces a current or forces a voltage, depending on which operating mode is selected. The SENSE pin is a high impedance analog input which measures the DUT voltage input in the FI / MV operating mode. FORCE and SENSE are brought out to separate pins to allow for remote sensing. I/V MONITOR I/V MONITOR is a real time analog output which tracks the sensed parameter. I/V MONITOR functionality is described in Table 3.

RS1 and RS2 are digital inputs to an analog MUX which establishes the full scale current range of the PMU. One of four current ranges can be selected by using RS1 and RS2 as shown in Table 2.

In the FI / MV mode, the output voltage is a 1:1 mapping of the DUT voltage. In the FV / MI mode, I/V MONITOR follows the equation: I(measured) = I/V MONITOR / (4.0 * REXT). Using nominal values for the external resistors, I/V MONITOR of +8.0V corresponds to Imax and -8.0V corresponds to Imin of the selected current range.

TEST AND MEASUREMENT PRODUCTS Circuit Description (continued)
HIZ HIZ is a digital input which places the FORCE output into a high impedance state, regardless of the operating mode (forcing current or voltage.) This function allows the PMU to be connected directly to the pin electronics without an isolation relay while NOT adding any leakage current. DISABLE DISABLE is a digital input which places DUT LTH, DUT GTL, I/V MONITOR, and PASS/FAIL* into high impedance states. Force Voltage / Measure Current Mode FORCE = IVIN / (4.0 * REXT) In the FV / MI mode, VINP is a high input impedance, analog voltage input that maps directly to the voltage forced at the DUT (see Figure 1), where FORCE = VINP . A current monitor is connected in series with the Op Amp driving the FORCE voltage. This monitor generates a voltage that is proportional to the current passing through it, and its output is brought out to I/V MONITOR. The monitor's voltage may also be evaluated using the Window Comparator whose operation is in accordance with the FV/MI functional truth table (Table 6). I/V MAX and I/V MIN are high impedance analog inputs that establish the upper and lower thresholds for the window comparator (see Table 4). In the FV / MI mode, a maximum voltage input corresponds to at least a maximum current output. Positive current is defined as current flowing out of the PMU. with positive current is defined as current flowing out of the PMU.
IVIN +8.0V 0V -8.0V Forced Current Imax (full scale) 0 Imin (full scale)
The voltage at I/V MONITOR follows the equation: I(measured) = I/V MONITOR / (4.0 * REXT). Nominally, the external resistors (RA, RB, RC, and RD) should be chosen such that Imax * REXT = 2.0V.
Force Current / Measure Voltage Mode In the FI / MV mode, IVIN is a high input impedance, analog voltage input that is converted into a current (see Table 5) using the following relationship:
Table 5.
The resulting DUT voltage is then tested via the SENSE input by a window comparator, whose functional truth table is shown in Table 7. I/V MAX and I/V MIN are high impedance analog inputs that establish the upper and lower thresholds for the window comparator. In the FI / MV mode, the reference inputs translate 1:1 to SENSE level thresholds.

TEST AND MEASUREMENT PRODUCTS Circuit Description (continued)
REXT Selection The Edge737 is designed for the voltage drop across RA, RB, RC, and RD to be 2V with the maximum current passing through them. However, these resistor values can be changed to support different applications. Increasing the maximum current beyond the nominal range is not recommended. However, decreasing the maximum current is allowed. Short Circuit Protection The Edge737 is designed to survive a direct short circuit to any voltage within the supply rails at the FORCE and SENSE pins. Transient Clamps The Edge737 has on-board clamps to limit the voltage and current spikes that might result from either changing the current range or changing the operating mode. Common Mode Error/Calibration In order to attain a high degree of accuracy in a typical ATE application, offset and gain errors are accounted for through software calibration. When forcing or measuring a current with the Edge737, an additional source of error, common mode error, should be accounted for. Common mode error is a measure of how the common mode voltage, VCM, at the input of the current sense amplifier affects the forced or measured current values (see Figure 2). Since this error is created by internal resistors in the current sense amplifier, it is very linear in nature. Using the common mode error and common mode linearity specifications, one can see that with a small number of calibration steps (see Applications note PMU-A1), the effect of this error can be significantly reduced.

Compensation Capacitors COMP1 and COMP2 are internal op amp compensation pins that require a 120 pF capacitor connected between the two pins. CAPI is an external noise compensation pin that can be used as a low pass filter to eliminate noise from the IVIN and VINP input pins through the connection of an external capacitor from CAPI to GND. The relationship between the roll-off frequency of noise filtered (in Hz) to the external capacitance (in farads) can be seen below: 1 Filter Frequency = 80,000 X CCAPI CA and CB are internal compensation pins that require a 120 pF capacitor connected between them. Power Supply Sequencing In order to help protect the Edge737 from a latch-up condition, it is important that VCC All Input Voltages VEE, and VCC GND VEE at all times.

FORCE Pin Output Voltage (Positive Headroom Requirement) The maximum positive voltage that can be forced at the FORCE pin by the Edge 737 in the force voltage/measure current (FV/MI) mode and the maximum compliance voltage that can appear at the FORCE pin in the force current/measure voltage mode (FI/MV) is a function of the positive power supply (VCC), device case temperature (Tc), and selected current range. The plot in Figure 3 depicts the typical positive voltage that can appear at the FORCE pin for various power supply combinations across the specified case temperature range of the device. All plots represent the Edge 737 being used with a 2V full-scale swing across the external current sense resistors for each range.
