AOZ32034AQV Datasheet | Alpha & Omega Semiconductors

Description The AOZ32034AQV 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 posed of full-bridge topology with resonant tank circuit to get best efficiency of power converter. The AOZ32034AQV 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 AOZ32034AQV have multiple protection functions such as VCC UVLO, over temperature protection to make the design more robust. The AOZ32034AQV is available in a 4mm×4mm QFN-23L package and is rated over a -40°C to +125°C ambient temperature range.
