The MP1921A 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 the high-side and low-side supplies force their outputs low in case of insufficient supply. The integrated bootstrap diode reduces external component count.
