General Description

The AOZ9510QI is an integrated half-bridge gate driver

with smart functions. The device includes one half-bridge

gate driver, capable of driving high-side and low-side Nchannel

MOSFETs. Using two AOZ9510QI for single

phase motor driver and three AOZ9510QI for three

phase motor drivers.

The device features multiple protection functions such as

VCC UVLO, and over temperature protection. Moreover,

AOZ9510QI provides adjustable gate drive sink and

source current control. By doing this control, user can

optimize performances of EMI and efficiency.

The AOZ9510QI is available in a 4mm×4mm QFN-23L

package and is rated over a -40°C to +85°C ambient

temperature range.
