NAME
DESCRIPTION
1
CHG_IN
Battery Charge Supply Input. Connect a 1µF ceramic capacitor from CHG_IN to G.
Battery Charger Output. Connect this pin directly to the battery anode (+ terminal), and to IN1
and IN2 pins. Bypass with 10µF ceramic capacitor to G.
2
3
BAT
REF
Reference Noise Bypass. Connect a 0.01µF ceramic capacitor from REF to G. This pin is
discharged to G in shutdown.
Active Low Reset Output. nRST asserts low for the reset timeout period of 65ms whenever the
ACT5830 is first enabled. This output is internally connected to OUT1 via a 15kΩ pull-up resistor.

nRST
IN2
Input supply to LDO2, LDO4, LDO6, and LDO8. Connect to BAT and IN1.
LDO4 Output. Capable of delivering up to 100mA of output current. Output is discharged to
ground with 1kꢀ when disabled.
OUT4
LDO6 Output. Capable of delivering up to 150mA of output current. Output is discharged to
ground with 1kꢀ when disabled.
7
8
OUT6
OUT8
LDO8 Output. Capable of delivering up to 250mA of output current. Output has high impedance
when disabled.
LDO2 Output. Capable of delivering up to 300mA of output current. Output has high impedance
when disabled.

18
ODI2
Push Button On/Off Input. Connect a push-button between this pin and BAT. There is an internal
200kꢀ pull down resistor to G. See the System Startup & Shutdown section for more information.
PWR_ON
Power Hold Input for REG and LDO1. Drive PWR_HOLD to a logic high to complete the startup
19 PWR_HOLD sequence. Drive the pin to a logic low to disable REG and LDO1. See the System Startup &
Shutdown section for more information.
