MP1924HR-LF-P

MP1924 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. Undervoltage 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. Available in QFN-10 (4mmx4mm) package. Applications includes motor drivers, telecom half-bridge power supplies, avionics DC-DC converters, two-switch forward converters and active-clamp forward converters.

• 100V, 4A, high frequency half-bridge gate driver

• Drives a 2.2nF load with 15ns rise time and 12ns fall time at 12V VDD
• TTL-compatible input
• Quiescent current of less than 150μA

Notes

MPS part numbers ending in "-P" and "-Z" are the same parts. P & Z only indicates reel size.
