Description

VCC

Internal circuit power supply. Bypass VCC to GND with a ceramic capacitor no

higher than 100nF.

AGND

I/O

Analog ground.

VNTC

Pull-up voltage source for the NTC function. VNTC is connected to VCC through

an internal MOSFET. VNTC is disconnected from VCC during sleep mode. VNTC

should be the pull-up voltage of the external NTC resistive divider.

NTC

Negative temperature coefficient (NTC) thermistor.

Programmable battery full voltage. Leave VB floating for 4.2V. Connect VB to

logic high for 4.45V. Connect VB to GND for 4.35V.

BATT

Positive battery terminal/battery charge current sense negative input.

CSP

Battery charge current sense positive input.

LED4

LED4 together with LED1, LED2, and LED3 achieves the voltage-based fuel

gauge indication.

LED3

LED3 together with LED1, LED2, and LED4 achieves the voltage-based fuel

gauge indication.

LED2

LED2 together with LED1, LED3, and LED4 achieves the voltage-based fuel

gauge indication.

LED1

LED1 together with LED2, LED3, and LED4 achieves the voltage-based fuel

gauge indication.
