NC

No Connection

13

CSP

Positive Input for Charging Current Sensing. This pin and the BAT pin

measure the voltage drop across the sense resistor RCS, to provide the

current signals required.

14

BAT

Battery Voltage Sensing Input and the Negative Input for Charging Current

Sensing. A precision resistor divider sets the regulation voltage on this pin in

constant voltage mode.

15

VCC

External DC Power Supply Input. VCC is also the power supply for internal

circuit. Bypass this pin with a capacitor.

16

DRV

Drive the gate of external P-channel MOSFET.
