Power chip

3.3V fixed output, Iout=700mA, Vin=6V(Max)

The NCP5304 is a high-voltage power gate driver driver with two outputs for direct drive of 2 N-channel power MOSFETs or IGBTs in a half-bridge configuration. It uses a bootstrap technique to ensure proper driving of the high side power switch. The driver uses 2 independent inputs with cross conduction protection.
