PIN DESCRIPTION
PIN
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
CDLY
Overcharge detection dead time setting pin.
Dead time can be set by adding a capacitor
between TD and GND pins.
6
VC1
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
VCC
Power supply input pin.
8
VC2
Voltage input for top terminal of upper cell
(C2).
