MPQ1922 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 MPQ1922 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 HSFET 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. The MPQ1922 is available in a QFN-22 (4mmx5mm) package with an exposed thermal pad. Applications include brushless DC (BLDC) motors and permanent magnet synchronous motor (PMSM) drives, high current brushed DC motor drives, automotive pumps, fans, superchargers, actuators, power drills and E-bikes.
