ADP5360CB-EVALZ

BATTERY PROTECTION FUNCTION EVALUATION

All battery protection voltage and current threshold settings,
hysteresis setting, and deglitch time is set up in the Battery
Protection Setting section, under the Charge Control tab,
shown in Figure 18.
Figure 18. GUI Charge Parameter Control Settings
Ensure the EN_BATPRO bit, corresponding indicator located
in the Charge Control tab (see Figure 11), is set to high and
that the battery protection feature is enabled and lit up.
Figure 19. GUI Charger_Status1 Settings
For UV protection, set the ISOB voltage lower than the default
2.5 V UV_DISCH, battery UV threshold value (see Figure 18).
Next, check that the BAT_UV_STATUS (see Figure 19) status
bit is set to high, the VSYS node voltage is shut down, and that
the battery is isolated from the VSYS side.
For overvoltage (OV) protection, set the battery simulator voltage
higher than the default 4.3 V OV_CHG, charge OV threshold (see
Figure 18) value. Then check that the BAT_OV_STATUS (see
Figure 19) status bit set to high and that the VSYS node is
isolated from the ISOB node.
User Guide
To enable the overdischarge current protection, set the VSYS
load current (see Figure 17) at the system output to the default
OC_DISCH, battery OC threshold value (see Figure 18). Next,
check that the battery ISOB node is isolated from the VSYS
side, and that the BAT_OC fault bit (see Figure 20) is set high
(BAT_OC lit up).
To enable overcharge current protection, set the charge current
higher than the default OC_CHG, charge OC threshold value
(see Figure 18). Next, check that the charger has shut down and
that the BAT_CHGOC fault bit (see Figure 20) is set high.

BUCK REGULATOR EVALUATION

Check that the EN1 jumper is set high on the evaluation board.
Next, set the EN_BUCK bit high by clicking EN_BUCK in the
GUI (see Figure 21).
Figure 21. GUI Buck Setting in BUCK & BCKBST Control Tab
In the Buck Setting section shown in Figure 21, keep the
BUCK_MODE bit low (default) to select buck operation as
hysteresis mode for low quiescent current. If the
BUCK_MODE bit is set high, the buck regulator operates in
force PWM (pulse-width modulation) mode for low noise
using a lower noise power requirement.
The default buck regulator output voltage is 1.2 V. Program the
VOUT_BUCK bits (see Figure 21) to set the other output voltages
in the VOUT_BUCK dropdown list.
