Pin Descriptions

Pin #

Pin Name

Pin Function

1

VIN

Supply pin

2STATB

Status output pin

VIN, and a charging cycle begins. It is released when the termination current is reached, indicating that charging is

complete. STATB is not asserted for re-charge cycles.

3

GND

Ground

4

IPRGM

Fast-charge and pre-charge current programming pin

a resistor from this pin to ground. Pre-charge current is 20% of fast-charge current. The charging termination

threshold current is 10% of the IPRGM programmed fast-charge current.

5BAT

Charger output

6

ENB

Combined device enable/disable — Logic high disables the device. Connect to GND to enable charging with

indefinite float-charging. Float this pin to enable charging without float-charge upon termination. Note that this

pin must be grounded if the SC810 is to be operated without a battery connected to BAT.
