Provide Original and Genuine Products MP1922 100V, 3A, Single-Channel, Half-Bridge Pre-Driver IC

Description

The MP1922 is a 100V, single-channel, integrated circuit (IC), half-bridge gate driver designed for motor driver applications and other power control applications. The two N-channel power MOSFETs are set up in a half H-bridge configuration, and operate on power supplies up to 100V.

The MP1922 combines a bootstrap (BST) capacitor and an internal charge pump to generate a supply voltage of the high-side MOSFET (HS-FET) driver. The device’s HS-FET driver generates a voltage above the power supply, which in many cases indefinitely maintains a high output at 100% duty cycle operation.

The half-bridge pre-driver features configurable slew rate control, FET desaturation protection, adjustable dead time (DT) control, under-voltage lockout (UVLO) protection, and thermal shutdown.

The MP1922 is available in a QFN-22 (4mmx5mm) package with an exposed thermal pad.
