General Description

The AOZ9530QV 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 N-channel

MOSFETs. Using two AOZ9530QV for single phase motor

driver and three AOZ9530QV for three phase motor drivers.

The device features multiple protection functions such as

over current protection, short circuit protection, and over

temperature protection. Moreover, AOZ9530QV provides

adjustable gate drive sink and source current control. By

doing this control, user can optimize performances of EMI

and efficiency.

The AOZ9530QV is available in a 3mm×3mm QFN-18L

package and is rated over a -40°C to +125°C ambient

temperature range.
