MPQ1923-AEC1

100V, 8A, High-Frequency, Half-Bridge Gate Driver, AEC-Q100 Qualified

Description

The MPQ1923 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 <5ns in time delay.

In the case of an insufficient supply, the device’s HS-FET and LS-FET under-voltage lockout (UVLO) protection functions force the outputs low. The MPQ1923 also features an integrated bootstrap (BST) diode to reduce the external component count.

The MPQ1923 is available in QFN-10 (4mmx4mm) and QFN-8 (4mmx4mm) packages.

Evaluation Tools

EVQ1923-RE-00A Evaluation Kit 100V, 8A, High-Frequency Half-Bridge Gate Driver Evaluation Board

The EVQ1923-RE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ1923, a high-frequency half-bridge gate driver. The MPQ1923 has a 7A source current (I_SOURCE) and 8A sink current (I_SINK) at a 12V driver power supply voltage (_VDD).

The integrated bootstrap (BST) diode reduces the external component count. The device’s high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET) drivers are controlled independently, and can be matched with a time delay (<5ns). If the IC supply is insufficient, then under-voltage lockout (UVLO) protection on both the HS-FET and LS-FET force the outputs low.

The MPQ1923 is designed for motor drivers and other power-control applications (e.g. telecommunication half-bridge power supplies, avionics DC/DC converters, two-switch forward converters, and active-clamp forward converters.

The MPQ1923 is available in small QFN-10 (4mmx4mm) and QFN-8 (4mmx4mm) packages.

The EVQ1923-RE-00A is configured as a buck converter. The INH and INL pins are independent signals. Choose complementary pulse-width modulation (PWM) signals and a proper dead time (DT) for INH and INL.
