AOZ9551QV分立半導(dǎo)體產(chǎn)品的功率驅(qū)動器模塊規(guī)格書PDF中文資料

General Description

The AOZ9551QV 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 AOZ9551QV for single phase motor

drivers and three AOZ9551QV for three phase motor drivers.

The device features multiple protection functions such as

short circuit protection and over temperature protection.

Moreover, AOZ9551QV provides adjustable gate drive sink

and source current control. By doing this control, the user

can optimize performances of EMI and efficiency.

The AOZ9551QV is available in a 5 mm×5 mm QFN-31L

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

temperature range.
