Description: The MC33567 Dual Linear Controller is designed for motherboard/mainboard applications requiring reliab...
The MC33567 Dual Linear Controller is designed for motherboard/mainboard applications requiring reliable regulation of high current supply planes. This advanced linear IC provides the necessary drive, sense, and control signals to interface two separate Nchannel MOSFETs as individual series pass elements regulating two different supply planes.
Use of this device lowers costs as well as ameliorates layout problems on pc motherboard products. Additionally, an under voltagebased short circuit detection and protection feature is provided which places system operation into a protected mode pending removal of the short.

• Detects under voltage condition (short circuit condition) and places regulation into a protective "hiccup" mode, thus preventing damage and permitting recovery after short circuit condition is corrected
• Drive capability for SOT223, DPAK, and D2PAK MOSFETs
• MC335671 controls two separate series pass transistors to provide regulation for separate 1.5V and a 1.8V supply planes. MC335672 controls two separate series pass transistors to provide regulation for separate 2.5V supply planes
