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.
