DFN3*3-10 Description
Function
OpenDrain Charge Status Output. When the battery is charging, the CHRG pin is
1
CHRG
pulled low by an internal Nchannel MOSFET. When the charge cycle is completed,
hen the ACE4101 detects an under voltage lockout condition, CHRG is forced high
impedance
Charge Current Program, Monitor the charge current and Shutdown. This pin set

ISET
to 1V in constantcurrent mode. The charge current is programmed by connecting a
1% resistor, RISET, to GND pin
3 Ctrl
Sense Feedback Voltage Pin
Enable Input Pin. Pulling the EN pin high places the ACE4101 into a low power
4 EN state where the BAT drain current drops to less than 3μA and the supply current is
reduced to less than 50μA. For normal operation, pull the pin low
5 FB
Battery Feedback Voltage
Positive Supply Voltage Input. This pin connects to the power devices inside the
6
VIIN
chip. VIN ranges from 4V to 5.5V for normal operation. Operation down to the under
voltage lockout threshold is allowed with current limited wall adapters. Decouple
with a 10μF or larger surface mounted ceramic capacitor
Switch Node Connection. This pin connects to the drains of the internal main and
7 SE
synchronous power MOSFET switches. Connect to external inductor
8 GND
Ground
9 CHRIN
Power Path Output Voltage

BAT
Battery Charger Output Terminal. Connect a 22μF ceramic chip capacitor between
BAT and PGND to keep the ripple voltage small
