Number

Pin Name

Pin Type

Pin Description

BATT

Input

Battery Voltage Sense – Connect directly to positive terminal of battery

and bypass with a 2.2uF or greater capacitor.

TRICKLE

SENSE

Input

Trickle Charge – Connect directly to positive terminal of battery.

Charge Current Sense – Connect directly to positive terminal of battery.

No Connect (may be connected to GND for easier routing of Ball D2).

Status Indicator.

STAT

Output

Input

Power

THERM

VDDCAP

Battery Thermistor Sense.

VDD Bypass – Connect to VDD bypass capacitor with 1uF or greater

capacitor.

AGND

GND

Ground

Input

Analog Ground – Connect to isolated PCB ground.

Ground – Connect to isolated PCB ground.

Voltage Input (+4.35V to +6.5V) – Bypass with a 2.2uF or greater

capacitor.

Input

Enable Input – Apply a logic-high voltage to enable and/or resume

charging. After assertion of the EN signal, the safety timers start

counting from the beginning. When unused, this pin should be tied to

GND (do not leave floating).

CHGSET

Input

Two-level charge current adjustment. Connect to VDDCAP for full

charge current. Connect to GND for 40mA. When unused, this

pin should be tied to VDDCAP (do not leave floating).

SDA

SCL

OUT

Input/Output I²C Bus Data.

Input

I²C Bus Clock.

Output

Charge Current Output.
