General Description

The AOZ32033AQI is an integrated half-bridge solution

with intelligent slew-rate control for wireless charger

application. The device includes the high-side, low-side

N-channel MOSFETs and its driver circuit. Typically, it's

dedicated for the design of wireless charger transmitter

circuit which is composed of full-bridge topology with

resonant tank circuit to get best efficiency of power

converter.

The AOZ32033AQI provides adjustable gate drive sink

and source current control, by doing this control

methodology, it's able to optimize EMI and driver losses

to improve overall efficiency performance. Moreover, the

features of AOZ32033AQI have multiple protection

functions such as VCC UVLO, over temperature

protection to make the design more robust.

The AOZ32033AQI is available in a 3mm×3mm QFN-18L

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

temperature range.
