APW8858 - Wide Input 5.4V to 21V Power Management

Datasheet Summary

Description

The APW8858 is a Power Management IC (PMIC) designed to provide complete Power Management solution for Intel GLK(

) plateform applications.

The IC operates from a single supply voltage of 5.4V to 21V allowing it to be used in 2 Cell to 4 Cell battery applications.

Features

  • such as over current, over voltage and internal under voltage lock out protection as well as thermal SD. The serial interface is an I2C communication interface which allows supply sequencing as well as controlled margining of ramp up and ramp down of all supplies to optimize battery power consumption. The I2C interface also allows for adjustability of Soft Start, Forced PWM/ Auto PFM/PWM, power sequencing as well output discharge and IRQ. The IC is offered in a small TQFN, 5x5-40L package for be.
