EVQ1922-V-00A

The EVQ1922-V-00A is an evaluation board designed for the MPQ1922, a half-bridge gate driver that can be used in motor drivers and other power control applications. The MPQ1922 drives two N-channel power MOSFETs in a half-bridge configuration, and can operate from power supplies up to 100V.

To prevent shoot-through in the output MOSFETs, the MPQ1922 generates an adaptive dead time (DT) by monitoring the gate driver output voltages. This ensures that each MOSFET gate has been fully discharged before the opposite MOSFET turns on. A longer DT can be generated by adding a delay between the INH and INL input signals.

The EVQ1922-V-00A can operate with a buck converter, and the INH and INL signals are independent of one another. The MPQ1922 is available in a QFN-22 (4mmx5mm) package, and is AEC-Q100 qualified.
