MP1925

100V, 4A, High Frequency Half-Bridge Gate Driver with Lower Vdd Threshold

Datasheet

Description

The MP1925 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 MP1925 is available in a QFN-8 (4mmx4mm) package.

EV1925-R-00A 100V, 4A Half-Bridge Gate Driver Evaluation Board

The EV1925-R-00A is an evaluation board for the MP1925, a high frequency Half-Bridge gate driver. Its high-side and low-side driver channels are independently controlled and matched with a time delay of less than 5ns. The demo board is configured as a buck converter. INH and INL are independent signals of each other. Complementary PWMs with proper dead time should be implemented for INH and INL.
