MP1923GR-P

MP1923 is a high-frequency, N-channel MOSFET, half-bridge gate driver. The device’s low-side MOSFET (LS-FET) and high-side MOSFET (HS-FET) driver channels are controlled independently, and are matched with <lt/>5ns in time delay. In the case of an insufficient supply, the device’s HS-FET and LS-FET under-voltage lockout (UVLO) protection forces the outputs low. The MP1923 also features an integrated bootstrap (BST) diode to reduce the external component count. Applications include motor drivers, telecom half-bridge power supplies, avionics DC/DC converters, two-switch forward converters and active-clamp forward converters.

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