Edge4707B Quad Channel Per-Pin Precision Measurement Unit
TEST AND MEASUREMENT PRODUCTS Description
The Edge4707B 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 quad channel per pin PMU. Each channel of the Edge4707B features a PMU that can force or measure voltage over a 15V I/O range, and supports 4 current ranges: 2 A, 200 A, 20 A, and 2 mA. Each channel of the Edge4707B features an on-board window comparator that provides two bits of information: DUT too high and DUT too low. There is also a monitor function which provides a real time analog signal proportional to either the measured voltage or current. The Edge4707B is designed to be a low power, low cost, small footprint solution to allow high pin count testers to support a PMU per pin. In addition, two independent switches per channel (for a central PMU force and sense) plus two wide voltage analog muxes per channel are included.

Edge4707B
TEST AND MEASUREMENT PRODUCTS Circuit Description
Circuit Overview The Edge4707B is a quad channel parametric test and measurement unit that can : * Force Voltage / Measure Current * Force Current / Measure Voltage * Force Voltage / Measure Voltage * Force Current / Measure Current Each PMU channel can force or measure voltage over a 15V range and force or measure current over four distinct ranges: * 2 A * 20 A * 200 A * 2 mA. An on-board window comparator provides two bit output range classification. Also, a monitor passes a real time analog voltage which tracks either the measured current or voltage. PPMU Functionality The trapezoid in Figure 1 describes the current-voltage functionality of the PMU with VCC = 15.5V and VEE = -4.5V, in Range D.
V VOUT (@ I = 0) = 13.25V VCC = +15.5V VOUT (@ 200 A) = 12.8V (in Range D) VOUT (@ 2 mA) = 11.25V No restrictions
Control Inputs FV/FI* is a TTL compatible input which determines whether the PMU forces voltage or current, and MI/MV* is a TTL compatible input which determines whether the PMU measures current or voltage. FV/FI* and MI/MV* are independent for each PMU. Table 1 describes the modes of operation controlled by these pins.

Table 1.
RS0 and RS1 are TTL compatible inputs to an internal analog mux which selects an external resistor corresponding to a desired current range. The truth table for RS0 to RS1, along with the associated external resistor values and current ranges, is shown in Table 2. RS0 and RS1 are independent for each channel of the 4707B.

Table 2.
FORCE/SENSE FORCE is an analog output which either forces a current or forces a voltage, depending on which operating mode is selected. SENSE is a high impedance analog input which measures the DUT voltage input in the MV operating mode. FORCE and SENSE are brought out to separate pins to allow remote sensing.

VOUT (@ 2 mA) = -0.25V VOUT (@ -200 A) = -1.8V (in Range D) VOUT (@ I = 0) = -2.25V VEE = -4.5V
NOTE: Negative current implies current is flowing into the 4707 from DUT.

TEST AND MEASUREMENT PRODUCTS Circuit Description (continued)
IVMON IVMON is a real time analog voltage output which tracks the sensed parameter. In the MV mode, the output voltage displayed at IVMON is a 1:1 mapping of the SENSE voltage. In the MI mode, IVMON follows the equation: IVMON = I(measured) * REXT Using nominal values for the external resistors (RA, RB, RC, and RD), a voltage at IVMON of +2V corresponds to Imax and -2V corresponds to Imin of the selected current range. The IVMON pin can also be placed into a high impedance state by using the DISABLE input (see Table 3).
Disable 1 0 0 MI / MV* X 0 1 Sensed Parameter High Impedance Measured Voltage Measured Current
Force Current Mode In the FI mode (FV/FI* = 0), IVIN is a high impedance analog voltage input that is converted into a current at the FORCE pin using the following relationship: Forced Current = IVIN / REXT (Positive current is defined as current flowing out of the FORCE pin.) The IVIN input voltage range and forced current (at FORCE) can be seen in Table 4.
IVIN +2V 0V -2V Corresponding Forced Current Imax (full scale) 0 Imin (full scale)
Table 4.
Measure Voltage Mode In the MV mode (MI/MV* = 0), DUT voltage is measured via the SENSE input pin. Note that EXT_SENSE_SEL = 0 when the Edge4707B SENSE is used. This measured voltage is also tested with the on-board window comparator. Comparator The Edge4707B features an on-board window comparator which provides two-bit measurement range classification. IVMAX and IVMIN are high impedance analog inputs that establish the upper and lower thresholds for the window comparator. In the MI mode, an I/V MAX input of +2V will set the upper threshold of the window comparator to a voltage corresponding to +FSC (full-scale current), and an I/V MIN input of -2V will set the lower threshold to a voltage corresponding to -FSC (positive current is defined as current flowing out of the PMU). DUTGTL the DUTLTH are LVTTL compatible outputs which indicate the range of the measured parameter in relation to IVMIN and IVMAX. Comparator functionality is summarized in Table 5 for MI Mode and Table 6 for MV mode.
Table 3.
Force Voltage Mode In the FV mode (FV/FI* = 1), VINP is a high impedance analog voltage input that maps directly to the voltage forced at the FORCE pin. Measure Current Mode In the MI mode (MI/MV* = 1), a current monitor is connected in series with the PMU forcing amplifier. This monitor generates a voltage that is proportional to the current passing through it, and is brought out to IVMON. This voltage (corresponding to the measured current) is also tested by the on-board window comparator.

Edge4707B
TEST AND MEASUREMENT PRODUCTS Circuit Description (continued)
REXT Selection The Edge 4707B 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 by increasing the external resistor using the equation IMAX = 2V / REXT. Switch Operation on Force and Sense Lines Each channel of the Edge4707B features two switches connected to the FORCE output pin (External Force = 45, Internal Force = 100) and one 1K switch connected to the SENSE input pin. These switches are controlled by the TTL compatible inputs I_FCSEL, E_FCSEL, and E_SNSEL. Switch operation is described in Table 7.
Switch Select Name I_FCSEL Open/Close State on Switch 0 = Open 1 = Closed 0 = Open 1 = Closed 0 = Open 1 = Closed
I_FCSEL 0 1 1 0 E_FCSEL 0 1 0 1 FORCE HiZ Illegal Condition VINP E_FC_IN
Table 8.
For external sense operation, the switch controlled by E_SNSEL can be used to internally connect the SENSE input pin to the E_SN_IN output pin (see Figure 2). This allows the user to use the E_SN_IN pin for remote sensing. Analog MUX The Edge4707B has a separate analog mux section which is intended for 12V flash programming signal muxing with lower, more standard voltages. There are five inputs for this section, all of which are brought out to external pins (see Figure 3). The two outputs, DVH and DVL, connect to driver reference voltages of the Edge720 (or other pin electronics drivers).

Table 7. These switches can be configured to route the Edge4707B for external forcing or sensing operations (see Figure 2). For external forcing operation, the switch controlled by I_FCSEL can be used to internally isolate the PMU from the FORCE output. This enables the user to connect the FORCE pin to an external device connected to the E_FC_IN pin using the switch controlled by the E_FC_SEL input. I_FCSEL and E_FCSEL functionality is described in Table 8.

Edge4707B
TEST AND MEASUREMENT PRODUCTS Circuit Description (continued)
Short Circuit Protection The Edge 4707B is designed to survive a direct short circuit to any legal voltage at the FORCE and SENSE pins, by virtue of a limited current, which results from the presence of an external current sense resistor (normally 1 K to 1M) in the FORCE path. Transient Clamps The Edge 4707B 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. Power Supply Sequencing In order to avoid the possibility of latch-up, the following power-up requirements must be satisified: 1. VEE GND VDD VCC at all times 2. VEE All inputs VCC The following power supply sequencing can be used as a guideline when operating the Edge4707: Power Up Sequence 1. VCC (substrate) 2. VEE/VDD 3. Digital Inputs 4.

Edge4707B
TEST AND MEASUREMENT PRODUCTS Application Information (continued)
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 operating the Edge4707B in the Measure Current (MI) or Force Current (FI) modes, 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 4). 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. Maximum Input Voltage Range for FV Mode In order to ensure that the full-scale output voltage range (FSV) can be achieved by the 4707B, errors such as gain, linearity, and offset must be taken into account when determining the input voltage range required at VINP The . equations in Table 10 can be used to determine the input voltage range required at VINP to achieve full scale voltage (FSV) at the FORCE pin.

Maximum Input Voltage Range for FI Mode In order to ensure that the full-scale output current range (FSC) can be achieved by the 4707B, errors such as gain, linearity, common mode, and offset must be taken into account when determining the input voltage range required at IVIN. The equations in Table 12 can be used to determine the input voltage range required at IVIN to achieve full scale current (FSC) at the FORCE pin.
IVIN (Worst Case) 2V + VOS + Common Mode Error + Linearity Error Gain -2V + VOS + Common Mode Error + Linearity Error Gain Corresponding Forced Current + FSC - FSC

Example: To guarantee that the 4707B is capable of forcing 2 mA with REXT = 1K (Range D), the input voltages in Table 13 may be required.
