Product Description

The MP18021 is a high frequency, 100V half bridge N-channel power MOSFET driver. Its low side and high side driver channels are independently controlled and matched with less than 5ns in time delay. Under voltage lock-out on both high side and low side supplies force their outputs low in case of insufficient supply. The integrated bootstrap diode reduces external component count.

Product Features

  • Drives N-channel MOSFET half bridge

Kit details

This is EV board documentation for MP18021A. The MP18021A is a high frequency, 100V half bridge N-channel power MOSFET driver. Its low side and high side driver channels are independently controlled and matched with a time delay of less than 5ns. Under-voltage lockout on both high side and low side supplies force their outputs low in case of insufficient supply. The integrated bootstrap diode reduces external component count.

This demo board is configured to a buck converter. INH and INL are independent signals of each other. For simplicity, the user only need to supply a PWM signal to this demo board and the on-board circuitry will generate INH and INL signals with proper dead time. In a real system, the controller will have to take care of dead time adjustment.
