NCP1393: High Voltage Half-Bridge MOSFET Driver with Inbuilt Oscillator Featuring Brown-out and Latched Enable Input

The NCP1393B is a self-oscillating high voltage MOSFET driver primarily tailored for the applications using half-bridge topology. Due to its proprietary high-voltage technology, the driver accepts bulk voltages up to 600 V. Operating frequency of the driver can be adjusted from 25 kHz to 250 kHz using a single resistor. Adjustable brown-out protection assures correct bulk voltage operating range. An internal 100 ms PFC delay timer guarantees that the main downstream converter will be turned on in the time the bulk voltage is fully stabilized. The device provides fixed dead-time which helps to lower the shoot-through current.
