QUICK START PROCEDURE
4. Increase PS2 until VBAT is 3.6V. Verify the input cur-
rent IIN is between 1.4A and 1.7A, the battery current
IBAT is between 3.75A and 4.45A and that the CHRG
LED and ACPR LED are on.
5. Increase PS2 until VBAT is 4.25V. Verify the battery
charging current IBAT is less than 5mA and that the
CHRG LED and ACPR LED are off.
6. Decrease PS2 until VBAT is 3.9V. Verify the battery cur-
rent IBAT is between 3.75A and 4.45A that the CHRG
LED and ACPR LED are on.
7. Decrease PS2 until VBAT is 3.6V. Connect a 10k resistor
from the RNG/SS pin to ground. Verify the charging
current IBAT is between 1.7A and 2.0A. Verify the volt-
age VNTC on the NTC turret is between 1.6V and 1.9V
and the voltage VRNG on the RNG/SS turret is between
450mV and 700mV. Remove the 10k resistor from the
RNG/SS pin to ground
8. Set JP1 to SHDN. Verify the charging current IBAT is
less than 5mA and that the FAULT LED, CHRG LED and
ACPR LED are off.
9. Set JP1 to RUN. Connect a jumper from the NTC pin to
ground. Verify the charging current IBAT is less than
5mA and that the FAULT LED, CHRG LED and ACPR
LED are on.
10. Remove the jumper from NTC to ground. Verify the
charging current IBAT is between 3.75A and 4.45A
and that the FAULT LED is off and the CHRG LED and
ACPR LED are on.
11. Turn on LOAD1 and set to 1A. Verify the voltage V
SYSTEM
on the system voltage turret is approximately equal
to V
IN
.
12. Turn off PS1, PS2 and LOAD1.
Figure 2. Proper Measurement Equipment Setup
NOTE: ALL CONNECTIONS FROM EQUIPMENT SHOULD BE KELVIN CONNECTED DIRECTLY TO THE BOARD PINS WHICH
THEY ARE CONNECTED TO ON THIS DIAGRAM AND ANY INPUT, OR OUTPUT, LEADS SHOULD BE TWISTED PAIR.
