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.
