Description
The MP1923 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 controlled independently, and are matched with a <5ns 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 MP1923 also features an integrated bootstrap (BST) diode to reduce the external component count.
The MP1923 is available in QFN-10 (4mmx4mm), QFN-8 (4mmx4mm), and SOIC-8 packages.

APPLICATION NOTE
AN216 - BRUSHLESS DC (BLDC) MOTOR PHASE UNDERSHOOTAPPLICATION NOTEIn brushless DC (BLDC) motor drive circuits, parasitic inductances on the PCB can often result in the motor phase nodes being driven to a negative voltage for a short period of time during switching. This issue is worse with high-current, low-inductance motors, where the dI/dt during switching can be very high. MPS’s BLDC pre-drivers, such as the MP653x family, are tolerant of negative transients...
