Pin #

Pin Name

Pin Function

1

BSEN

Battery voltage sense. Connect to battery positive terminal for Kelvin voltage sensing, VOUT otherwise. Do not leave open.

2CTO

Cold Temperature Offset. Adjustable NTC input high voltage (cold temperature) threshold. When the pin is

connected to GND the NTC high voltage threshold defaults to VT

3

IPRGM

Charger current program pin for fast-charge mode. Requires a resistor to GND to program fast-charge current.

4

ITERM

Charger termination current program pin. Requires a resistor to GND to program pre-charge and termination current.

5

RGND

Reference ground. Connect to battery’s negative terminal for Kelvin voltage sensing, GND otherwise. Do not leave open.

6

GND

Ground.

7

NTC

Input for battery NTC thermistor network. Voltage between VT

CTO voltage (VT

this range suspend charging and drive FLTB pin active (low). Voltage below VT

SC804 and resets the charge timer (with FLTB pin inactive).

8

FLTB

Open drain fault indicator. Active low when a fault condition occurs.

9

AFC

Analog Fast Charge input. Connect to a DAC for analog control of fast charge current level, connect to VCC to

disable this feature. Do not leave open.

10

CHRGB

Open drain charge status indicator. Active low when the charger is on and the output current exceeds

the termination current setting, high impedance when I

11

CPB

Open drain charger-present indicator. Active low when VCC exceeds UVLO.

12

RTIM

Programmable timer input pin. Connect to VCC to select the default time-out of 3 hours, connect to GND

to disable timer, or connect an external resistor to GND to program the time-out period.

13

OVPB

Open drain over-voltage indicator. Active low when an input over-voltage fault occurs.

14

VCC

Input supply pin. Connect to adapter power.

15

VOUT

Charger output. Connect to battery.

16

VOUT

Charger output. Connect to battery.

T

THERMAL

PAD

Thermal-conduction pad on bottom of the package. Solder directly to the ground plane with multiple

thermal vias to all other ground planes.
