DESCRIPTION
The MPQ1922 is a 100V, single-channel,integrated circuit (IC) gate driver designed for motor driver applications and other powercontrol applications. The two N-channel powerMOSFETs are set up in a half H-bridge configuration, and operate on power supplies up to 100V. The device is qualified to AEC-Q100 for automotive use.The MPQ1922 combines a bootstrap (BST)capacitor and an internal charge pump togenerate a supply voltage of the high-sideMOSFET (HS-FET) driver. The device’s HS-FET driver generates a voltage above thepower supply, which in many cases indefinitely
maintains a high output at 100% duty cycleoperation.The half-bridge pre-driver features configurableslew rate control, FET desaturation protection,adjustable dead-time control, under-voltagelockout (UVLO), and thermal shutdown.The MPQ1922 is available in a QFN-22(4mmx5mm) package with an exposed thermal
pad.
