BD39012EFV-C
System Regulator for microcontroller for automotive

BD39012EFV-C is a power management IC with 1ch DC/DC convertor, 1 ch LDO, reset and watch dog timer. It can supply the power supply to module from battery directly. LDO has reset built-in and always watches that it supplies stable power supply to module. In addition, window watch dog timer is provided to detect the abnormality of the microcomputer. BD39012EFV-C enables a superior heat dissipation and a compact PCB design by HTSSOP-B24 package.
