EVQ1922-V-00A

EVQ1922-V-00A is an evaluation board designed for the MPQ1922, a half-bridge gate driver that can be used in motor driver and other power control applications. The device drives two N-channel power MOSFETs in a half-bridge configuration, and operates on power supplies up to 100V. To prevent shoot-through in the output MOSFETs, the MPQ1922 generates an adaptive dead time by monitoring the gate driver output voltages. This ensures that each MOSFET gate has been fully discharged before the opposing MOSFET turns on. A longer dead time can be generated by providing a delay between the INH and INL input signals. The EVQ1922-V-00A is confirmed for a buck converter. The INH and INL signals are independent of one another. The MPQ1922 is available in a QFN-22 (4mmx5mm) package.
