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
NTCC×V
VCC.
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
NTCH×V
VCC, normally the hot threshold, and the CTO voltage
(VT
NTCC×V
VCC if CTO is tied to GND), normally the cold threshold, enables charging. Voltages outside this range suspend
charging and drive FLTB pin active (low). Voltage below VT
NTCDIS (nominally 0.6V) disables the SC804A 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
VOUT < ITERM.
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 hrs., 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.
