MC33567D-3R2 Description

The MC33567D-3R2 Dual Linear Power Supply Controller is designed to facilitate power management for motherboard applications where reliable regulation of high current supply planes is required. It provides the Drive, Sense, and Control signals to interface two external, N?channel MOSFETs for regulating two different supply planes. Undervoltage short circuit detection places the operation of the system into a protected mode pending removal of the short.
