Triple, Half-Bridge Motor Driver with Serial Input Control and AEC1 Qualification
The MPQ6523 from MPS, is a triple, half-bridge, DMOS, output driver with integrated power MOSFETs that can drive up to three different loads.
The three half-bridges can be controlled separately from a standard serial data interface and have various diagnostic functions. The MPQ6523 has very low quiescent current in standby mode, making it suitable for a wide range of applications. Full protection features include short-circuit protection (SCP), under-voltage protection (UVP), and thermal shutdown. The MPQ6523 requires a minimal number of readily available, standard, external components and is available in a QFN-24 (4x4mm) package.
