The MPQ6524 is a four half-bridge, DMOS, output driver with integrated power MOSFETs that can drive up to four different loads.
The four half-bridges can be controlled separately from a standard serial data interface and have various diagnostic functions. The MPQ6524 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 MPQ6524 requires a minimal number of readily available, standard, external components and is available in a QFN-24 (4mmx4mm) package.
