MP18024 Datasheet, PDF (1/12 Pages) Monolithic Power Systems – 100V, 4A, High Frequency Half-Bridge Gate Driver

The Future of Analog IC Technology
DESCRIPTION
The MP18024 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 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.
