PIN DESCRIPTIONS
PIN 1:
OC
- PMOS open drain output for control
of the charge control MOSFET M2. In
normal mode, this PMOS turns on to
pull the gate of the MOSFET M2 to
high, then the MOSFET M2 turns on.
When overcharge occurs, this PMOS
turns off, then no current flows
through R3 and the MOSFET M2
turns off.
PIN 2:
GND - Ground pin. This pin is to be
connected to the negative terminal of
the battery cell.
PIN 3:
OD
- Output
discharge
When overdischarge occurs, this pin
pin
for
control
MOSFET
of
the
M1.
control
goes low to turn off the MOSFET M1
and discharging is inhibited.
PIN 4:
CS
- Input pin for current sensing. Using
the sum of drain-source voltages of
the MOSFET M1 and the MOSFET
M2 (voltage between CS and GND),
it senses discharge current during
normal mode and detects whether
charge current is present during
power-down mode. It also used to
detect whether load is connected
during overcharge mode.
PIN 5:
VCC - Power supply pin. This pin is to be
connected to the positive terminal of
the battery cell.
