PIN DESCRIPTION

SYMBOL

DESCRIPTION

1

CF

Charge FET drive pin, must have common

emitter NPN to drive FET gate.

Overcharge detection output pin

PNP open collector output

2

DF

Discharge control FET (N-ch) control output

pin.

3

CS

Overcurrent detection input pin.

Monitors discharge current equivalently by

the voltage drop between discharge FET

source and drain. Stops discharge when

voltage between CS pin and GND pin goes

above overcurrent detection threshold value,

and holds until load is released.

4

GND

Ground pin, or lower cell (C1) negative pin.

5

Overcharge detection dead time setting pin.

Dead time can be set by adding a capacitor

between TD and GND pins.

6

Voltage input for positive terminal of bottom

cell (C10).

Connection pin for lower cell (C1) positive

electrode side and upper cell (C2) negative

electrode side.

7

Power supply input pin.

8

Voltage input for top terminal of upper cell

(C2).
