The MPQ1923-AEC1 from Monolithic Power Systems is a high-frequency half-bridge gate driver that provides a protected solution for driving motors, power supplies, two-switch forward converters, and active-clamp forward converters.
Featuring an integrated bootstrap diode, the MPQ1923-AEC1 reduces the external component count. The gate driver drives a 1 nF load with a rise time of 7.2 ns and a fall time of 5.5 ns at 12 V, making it suitable for use in high-frequency switching converters.
The low- and high-side N-channel MOSFET driver channels are controlled independently, and are matched with a time delay of less than 5 ns. In the event of an insufficient power supply, the under-voltage lockout protection function forces the outputs to the low- and high-side MOSFETs to low.
The MPQ1923-AEC1 is supplied in two QFN package options with ten or eight leads, both with a footprint of 4 mm x 4 mm.
Part supported: MPQ1923-AEC1
Board part number: EVQ1923-RE-00A
The EVQ1923-RE-00A evaluation board demonstrates the capabilities of the MPQ1923-AEC1, a high-frequency half-bridge gate driver that has a voltage rating of 100 V. The MPQ1923-AEC1 is intended for use in motor drivers, and in other power-control applications in telecoms servers, and avionics and industrial equipment.
The EVQ1923-RE-00A is configured as a buck converter.
