Pin descriptions
V
Voltage output. The drain of internal MOSFET. The output ON/OFF switching slew rate is
internally limited to improve the EMI parameters and to prevent glitches on the supply rails.
Maximum output current is 3.7 A.
PB
Push-button bypass. This is standard CMOS logical input. This input bypasses the voltage
monitoring and forces the output ON or OFF (assuming no other input is driven high, see
Table
GND (pin 4)
Ground.
PB (pin 5)
Push-button input. This input is equipped with voltage detector with a factory-trimmed
threshold. A momentary push-button switch to V
is pressed and held, the battery voltage is detected and the MOSFET is turned ON only if
the battery voltage is above the threshold V
factory-trimmed thresholds).
PS
Power supply hold input. This input may be driven by the application controller, and allows a
wide range of input levels (for use with 1.8 V or 2.85 V controller I/O voltage range).
V
Voltage input and power supply pin. The source of internal MOSFET. Operating voltage
range is 2.5 to 5.5 V.
Exposed pad
The exposed pad is internally connected to V
1, 2 on the PCB. This pad is not the primary V
