GENERAL DESCRIPTION

The ACT81460

is

a

low

power

PMIC

(power

management integrated circuit) that is specifically

designed for battery operated systems and is suitable

for a variety of processor applications. It features very

low standby current that prolongs battery life between

charges, especially in applications requiring long stand

by or low power mode durations. It is a highly efficient

PMIC that also enhances battery run time during normal

operating modes. The number of regulators that can be

turned OFF or left ON during low power modes is

configurable and offers users flexibility to optimize

system efficiency.

The IC includes four DC/DC converters with integrated

power FETs, three low-dropout regulators (LDOs), and

three load switches. Two of the DC/DC converters are

step down buck regulators, one is a step up/down buck-

boost regulator and the fourth is a high voltage step-up

boost regulator capable of providing up to 20V. Each

regulator can be configured for a wide range of output

voltages through the I2C interface.

The ACT81460

is

highly

configurable.

It

offers

configurable power sequencing combinations, startup

timing,

output

voltage

settings,

fault

monitoring,

interrupt control, programmable GPIO options, and

many more features. The device is pre-configured at the

factory with default configuration settings that can be

further adjusted though firmware via the standard I2C

interface to suit individual system requirements. The IC

also features the ability to sequence external power

supply rails as part of the power up sequence by using

GPIOs.

The ACT81460 PMIC is available in a 3.33mm x

3.28mm, 49 ball WLCSP package.
