GENERAL DESCRIPTION
The patent-pending ACT5830 is a complete, inte-
grated power management solution that is ideal for
mid-high and mobile phones. This device integrates
a linear Li+ battery charger with an internal power
MOSFET, a high efficiency 350mA DC/DC con-
verter, eight low dropout linear regulators, a reset
output, and two N-Channel open drain switches,
and an I
2
C Serial Interface to achieve flexibility for
programming LDO outputs and individual on/off
control.
The charger is a complete, thermally-regulated,
stand-alone single-cell linear Li+ battery charger
that incorporates an internal power MOSFET
for constant-current/constant-voltage control. The
charger includes a variety of value-added features,
and it is programmable via the I
2
C-Interface to con-
trol charging current, termination voltage, along with
safety features and operation modes.
The ACT5830 is available in a compact 5mm x
5mm 40-pin Thin-QFN package that is just 0.75mm
thin.

DESCRIPTION
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.
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.
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 1kΩ when disabled.
LDO6 Output. Capable of delivering up to 150mA of output current. Output is discharged to
ground with 1kΩ when disabled.
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.
LDO6 Independent On/Off Control. Drive to a logic high for normal operation, and to a logic low
to disable.
LDO4 Independent On/Off Control. Drive to a logic high for normal operation, and to a logic low
to disable.

C Serial Interface. Data is read on the rising edge of the clock.
Clock Input for I
2
C Serial Interface. Data is read on the rising edge of the clock.
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.

N-channel Open–Drain Output 2. State of output controlled by 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.
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.
Power Hold Input for REG and LDO1. Drive PWR_HOLD to a logic high to complete the startup
PWR_HOLD sequence. Drive the pin to a logic low to disable REG and LDO1. See the
System Startup &
Shutdown
section for more information.
