The MPQ6528 is an H-bridge gate driver IC that can drive two half-bridges with four N-channel power MOSFETs across a wide 5V to 60V input voltage (VIN) range. The device’s integrated, regulated charge pump generates gate driver power (VREG), and a bootstrap (BST) capacitor generates the supply voltage for the high-side MOSFET (HS-FET) driver. An internal trickle-charge circuit maintains a sufficient HS-FET gate driver voltage even at 100% duty cycle.

Full protection features include configurable short-circuit protection (SCP), over-current protection (OCP), under-voltage lockout (UVLO) protection, adjustable dead time (DT) control, and thermal shutdown. The MPQ6528 is available in a QFN-28 (4mmx5mm) package with an exposed thermal pad.
