Equipment Setup
(a) Verify that the jumpers are in the correct location. JP5/4/3/8/15/12/11/13/6/16 are to be set to SYS-
OUT, JP7 to +5V, JP14 to RES, JP15 to LDO1, and JP1/2/17/18/9; apply jumper across the two pins.
See
(b) Adjust POT R19 until TP16/A1gnd reads 37K, using DMM.
(c) Adjust POT R12 fully clockwise.
(d) Connect the loads shown in
. These are suggested loads, but the user can substitute any load
that is within the specification of the IC. The PWM and LED_PWM are open-drain outputs and require
a external pullup resistor to OUT (System Power). TB6-1 or TP29 can be used as a source for
SYS_OUT.
(e) Connect the battery-simulated load board shown in
below UUT; leave bias supply off. A
single-cell Li-ion battery can be used in place of the simulated battery if quick battery voltage
adjustment is not needed for evaluation. The battery supply should be the first supply on and the last
supply off to avoid putting the BAT output on an unpowered external supply. A power Schottky diode
can be placed in series with the positive lead (anode to P/S+) of the battery supply to protect the
supply, if necessary.
(f) Connect USB cable to computer’s USB port and the other end to the EV2300 box. Connect the I2C
cable between the EV2300 box and the UUT to TB3
(g) Preset P/S#1 to 5.1 VDC+/-0.1VDC, Current Limit to 2.5A, P/S#2 to 3.5VDC+/-0.1VDC, Current Limit
to 2.5A, turn off supplies, connect P/S#1 to TB5-1&2 (+ to AC), and connect P/S#2 to TB7-1&2 (+ to
BAT_OUT). See
