DESCRIPTION

The MP1907 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

both high side and low side supplies force their

outputs low in case of insufficient supply. Both

outputs will remain low until a rising edge on

either

input

is

detected.

The

integrated

bootstrap diode reduces external component

count.

FEATURES

• Drives N-channel MOSFET half bridge

• Input signal overlap protection

• On-chip bootstrap diode

• Typical 20ns propagation delay time

• Less than 5ns gate drive mismatch

• Drive 1nF load with 12ns/9ns rise/fall times

with 12V VDD

• TTL compatible input

• Less than 150μA quiescent current

• UVLO for both high side and low side

• In 3×3mm QFN10 Packages

APPLICATIONS

• Battery Powered Hand Tool

• Telecom half bridge power supplies

• Avionics DC-DC converters

• Active-clamp Forward Converters
