MP1924A
100V, 4A, High Frequency
Half-Bridge Gate Driver
The Future of Analog IC Technology
DESCRIPTION
The MP1924A is a high-frequency, half-bridge,
N-channel power MOSFET driver. Its low-side
and high-side driver channels are controlled
independently and matched with less than 5ns
of time delay. Under-voltage lockout (UVLO) on
both the high-side and low-side supplies forces
the outputs low in the event that the supply is
insufficient. The integrated bootstrap diode
reduces the external component count.
The MP1924A is available in QFN-10
(4mmx4mm) and SOIC-8 packages.
