NAME

DESCRIPTION

CHG_IN

Battery Charge Supply Input. Connect a 1µF ceramic capacitor from CHG_IN to G.

BAT

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.

REF

Reference Noise Bypass. Connect a 0.01µF ceramic capacitor from REF to G. This pin is

discharged to G in shutdown.

nRST

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.

IN2

Input supply to LDO2, LDO4, LDO6, and LDO8. Connect to BAT and IN1.

OUT4

LDO4 Output. Capable of delivering up to 100mA of output current. Output is discharged to

ground with 1kΩ when disabled.

OUT6

LDO6 Output. Capable of delivering up to 150mA of output current. Output is discharged to

ground with 1kΩ when disabled.

OUT8

LDO8 Output. Capable of delivering up to 250mA of output current. Output is discharged to

ground with 1kΩ when disabled.

OUT2

LDO2 Output. Capable of delivering up to 300mA of output current. Output is discharged to

ground with 1kΩ when disabled.

TX_EN

LDO6 Independent On/Off Control. Drive to a logic high for normal operation, and to a logic low

to disable.

TCXO_EN

LDO4 Independent On/Off Control. Drive to a logic high for normal operation, and to a logic low

to disable.

SDA

Data Input for I2C Serial Interface. Data is read on the rising edge of the clock.

SCL

Clock Input for I2C Serial Interface. Data is read on the rising edge of the clock.

ODI1

Digital Control for Open Drain N-channel Switch 1. Drive to a logic high to turn on the switch.

Drive to a logic low to turn off the switch.

OD1

N-channel Open–Drain Output 1. State of output controlled by ODI1.

OD2

N-channel Open–Drain Output 2. State of output controlled by ODI2.

ODI2

Digital Control for Open Drain N-channel Switch 2. Drive to a logic high to turn on the switch.

Drive to a logic low to turn off the switch.

PWR_ON

Push Button On/Off Input. Connect a push-button between this pin and BAT. There is an internal

200kΩ pull down resistor to G. See the System Startup & Shutdown section for more information.

PWR_HOLD

Power Hold Input. Drive PWR_HOLD to a logic high to complete the startup sequence. Drive the

pin to a logic low to disable IC. See the System Startup & Shutdown section for more information.

No Connect. Not internally connected.

RX_EN

LDO5 Independent On/Off Control. Drive to a logic high for normal operation, and to a logic low

to disable.

OUT1

LDO1 Output. Capable of delivering up to 300mA of output current. Output is discharged to

ground with 1kΩ when disabled.

OUT7

LDO7 Output. Capable of delivering up to 250mA of output current. Output is discharged to

ground with 1kΩ when disabled.
