NDESCRIPTION
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 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,
adjustable dead-time control, under-voltage
lockout (UVLO), and thermal shutdown.
The MP1922 is available in a QFN-22
(4mmx5mm) package with an exposed thermal
pad.
