Description
The GS7001 is a complete constant-current/
constant voltage linear charger for cell
lithium-ion batteries. Its package and low
external component count make the GS7001
ideally suited for portable applications. The
charge current can be programmed externally
with a single resistor. GS7001 determines the
charge mode by detecting the battery voltage:
Pre-charge, constant current charging, constant
voltage charging. The charge current of
pre-charging and constant –current charging is
adjustable. The GS7001 is monitored by
temperature monitor during the constant-current
and constant-voltage charging. There are two
LEDs indicate the charge mode.
The GS7001 charger converters are available in
the SOP-8L packages (or upon request).

Application Information
PIN ASSIGNMENT
CHRG1 (Pin 1): Charge Status Indication. When the battery is charging, the CHRG1 pin is pulled low.
When the charge cycle is completed or reverse battery lockout / No AC is detected, CHRG is forced
high impedance. The battery is not working properly or when the temperature exceeds the set range,
output 50% duty cycle of 2Hz pulse, the PIN is available through 330 ohm resistors and indicates that
the light-emitting diode connected.
TS (Pin 2): Temperature Sense.
GND (Pin 3): Ground.
VOUT (Pin 4): Charge Current Output. It should be bypassed with at least a 10uF capacitor. It
provides charge current to the battery and regulates the final float voltage to 8.4V.
PDRI (Pin 5): Driving side. Connect to the grid of the PMOS.
CS (Pin 6): Charge Current Program, Charge Current Monitor and Shutdown Pin. The charge current
is programmed by connecting a resistor, RSET, ISET = V（CS）/RSET.
CHRG2 (Pin 7): End-of-Charge Status Indication. When the battery is charging, the CHRG2 pin is
forced high impedance. When the charge cycle is completed, CHRG2 is pulled GND.
VIN (Pin 8): Positive Input Supply Voltage. It Provides power to the charger VIN and should be
bypassed with a 10uF capacitor.
