General Description

The AOZ32103MQV-06 is a high performance

three-phase motor driver. It is able to drive three

half-bridges consisting of six N-channel power MOSFETs

for three-phase application.

AOZ32103MQV-06 has a very low shutdown current (< 1µA)

when nSLEEP pin is low, which is very suitable for portable

products. Built-in trickle charge pump allows the high side

driver output to maintain a high level. It also has a built-in

current amplifier, which can be used to feed back the total

current of the system. The device features multiple protection

functions such as internal safety features including shootthrough protection, adjustable dead-time control, VDD under

voltage protection and over temperature protection, and has

a reporting mechanism.

The AOZ32103MQV-06 is available in a 5 mmx4mm

QFN-28L package and is rated over a -40⁰C to +125⁰C

ambient temperature range.
