GENERAL DESCRIPTION
The Low-Side MOSFET has ultra-low ON resistance to minimize conduction loss. The AOZ5312UQI uses a PWM input for accurate control of the power MOSFETs switching activities, is compatible with 3V and 5V (CMOS) logic and supports Tri-State PWM. A number of features are provided making the AOZ5312UQI a highly versatile power module. The bootstrap switch is integrated in the driver. The Low-Side MOSFET can be driven into diode emulation mode to provide asynchronous operation and improve light-load performance. The pin-out is also optimized for low parasitics, keeping their effects to a minimum.FEATURES
