Measuring VCE (SAT) on Other Channels
1. Configure the board as described in “Initial Board Setup
Procedure” on page 4 .
2. Ensure that SW5 EN toggle switch is in the “L” down position
to disable the IC.
3. Move the ammeter and decade box to the new Cx channel
that the user wants to test. Move the voltmeter to measure
the voltage from the new Cx channel to VEE. Remove the Jx
jumper from that channel. Configure the SW0 A0 - SW4 A4
toggle switches to the appropriate logic levels to select the
new Cx channel. Refer to the truth table on page 5 of the
ISL72813SEH datasheet.
For example, if the user wants to perform the measurement
on the C26 channel, connect the ammeter/decade box at the
C26 pin on the evaluation board. Connect the voltmeter
across the C26 pin and VEE. Remove jumper J26 to
disconnect its LED circuitry. Set the toggle switches
SW0 A0 = “L”, SW1 A1 = “H”, SW2 A2 = “L”, SW3 A3 = “H”,
and SW4 A4 = “H”.
4. Repeat steps 2 - 5 in “VCE (SAT) Measurements for Channel
C0” on page 4 for the new Cx channel.
5. Note: The performance curves shown in Figure 13 on page 17
was taken using the evaluation board and a Keysight B2902A
precision source/measurement unit.
Test conditions:
a. The B2902A unit was set to measure and graph VCE
(SAT) vs ICX as the user sweeps the ICX in 10mA
increments from 0mA to 600mA.
b. V

c. Channels CH0, CH8, CH16, CH24, and CH31 were
measured. The plots in Figure 13 are the average of
these channels.
