DESCRIPTION

The MPQ1923-AEC1 is a high-frequency, Nchannel

MOSFET, half-bridge gate driver. The

device’s low-side MOSFET (LS-FET) and highside

MOSFET (HS-FET) driver channels are

controlled independently, and are matched with

<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

MPQ1923-AEC1 also features an integrated

bootstrap (BST) diode to reduce the external

component count.

The MPQ1923-AEC1 is available in QFN-10

(4mmx4mm) and QFN-8 (4mmx4mm)

packages.
