General Description

The AOZ9511QV 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 AOZ9511QV for single phase motor

drivers and three AOZ9511QV for three phase motor drivers.

The device features multiple protection functions such

as UVLO and over temperature protection. Moreover,

AOZ9511QV provides adjustable gate drive sink and source

current control. By using this control, the user can optimize

performances of EMI and efficiency.

The AOZ9511QV is available in a 4 mm×4mm QFN-23L

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

temperature range.
