5.
Increase PS2 until VBAT is 8.5V. Verify the battery
charging current, IBAT, is less than 5mA and that
the CHRG LED is off.
6.
Decrease PS2 until VBAT is 7.8V. Verify the bat-
tery current, IBAT, is between 1.775A and 2.225A
and that the CHRG LED is on.
7.
Set JP1 to 0. Verify the charging current, IBAT, is
less than 5mA and that the FAULT LED and the
CHRG LED are off.
8.
Set JP1 to 1. Connect a jumper from the NTC pin
to ground. Verify the charging current, IBAT, is
less than 5mA and that the FAULT LED and the
CHRG LED are on.
9.
Remove the jumper from NTC to ground. Verify
the charging current, IBAT, is between 1.775A and
2.225A and that the FAULT LED is off and the
CHRG LED is on.
10.
Turn on LOAD1 and set to 1A. Verify the voltage,
Vsystem, on the System Load turret is approxi-
mately equal to Vin.
11.
Set JP2 to 0. Verify the battery charging current is
less than 5mA and that the CHRG LED is off.
12.
Increase PS1 to 14V. Verify the charging current
is between 1.775A and 2.225A and that the CHRG
LED is on. Set JP2 to 1.
13.
Set JP4 to 0. Verify the battery charging current is
less than 5mA and that the CHRG LED is off.
14.
Increase PS1 to 17.7V. Verify the charging current
is between 1.775A and 2.225A and that the CHRG
LED is on. Set JP4 to 1.
15.
Turn off PS1, PS2 and LOAD1.
