SNS
Sense Input. Connect to the drains of the charge and discharge FETs. Used as a voltage reference for
detecting short-circuit and discharge overcurrent conditions.
31
CC
Charge Control Output. CC controls the gate of the charge FET. Driven from PKP to VOLCC to turn on and
turn off the charge FET.
32
PKP Pack Positive. The voltage on PKP is used to detect charger-attach and protection-release conditions.
