SYMBOL

DESCRIPTION

1

VM

Monitor pin. Detects overcurrent and the

presence of a charger.

2

Positive supply voltage input pin. Connect to

positive terminal of the cell.

3

Charge Time Delay pin. The capacitor

connected to this pin sets the delay.

4

CF

Charge FET pin. This drives the gate of the

charge control N-ch FET.

5

GND

Ground pin. Connect to negative terminal of

the cell.

6

DF

Discharge detection pin. This drives the gate

of the discharge N-ch FET.
