EMQ8932
4-Channel Power Management IC For
Portable Devices
General Description
The EMQ8932 is a high efficiency, 4-channel power
management IC for portable devices application. It
integrates a complete linear charger for single cell
lithium-ion battery, a linear regulator and two high
efficiency step-down DC/DC converters.
The linear charger (CH1) operates from 4.25V to 5.5V
input voltage and up to 1A charging capability. It is
thermal regulated and specifically designed to work
within USB power specifications.
The linear regulator (CH2) features ultra-high power
supply rejection ratio (75dB at 1kHz), low output voltage
noise (30µV), low dropout voltage (270mV), low
quiescent current (110µA) and fast transient response. It
operates from 2.5V to 5.5V input voltage, up to 600mA
loading capability and regulates adjustable output
voltage from 1.2V to 5.0V.
The two Synchronous Buck converters (CH3, CH4)
operate from 2.5V to 5.5V input voltage, up to
600mA loading capability and regulate adjustable
output voltage from 0.6V to VIN. It features low
quiescent current, fixed 1.5MHz internal frequency
operation.
The EMQ8932 is available in TQFN24 4x4 package,
It is Green compliant (RoHS and Halogen-free).
