MPQ1925

MPQ1925

100V, 4A, High-Frequency, Half-Bridge Gate Driver

Description

The MPQ1925 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 independently controlled, and are matched with less than 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 MPQ1925 also features an integrated bootstrap (BST) diode to reduce the external component count.

The MPQ1925 is available in a QFN-8 (4mmx4mm) package.

Evaluation Tools

EVQ1925-R-00A Evaluation Kit 100V, 4A, High-Frequency, Half-Bridge Gate Driver Evaluation Board

The EVQ1925-RE-00A evaluation board is designed to demonstrate the capabilities of the MPQ1925HR, a high-frequency, half-bridge gate driver. The MPQ1925HR has a 3A source current and a 4.5A sink current at 12V V_DD. The quiescent current (I_Q) is below 150μA.

The MPQ1925HR’s integrated bootstrap (BST) diode reduces the external component count. The device’s low-side MOSFET (LS-FET) and high-side MOSFET (HS-FET) driver channels are independently controlled, and are matched with less than 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 MPQ1925HR is available in a small QFN-8 (4mmx4mm) package. It is designed for motor drivers and other power control applications, such as telecommunication half-bridge power supplies, avionics DC/DC converters, two-switch forward converters, and active-clamp forward converters.

The EVQ1925-R-00A is configured as a buck converter. INH and INL are independent signals that require complementary pulse-width modulations (PWMs) and a proper dead time (DT).
