CG8513 Data Sheet Type Description: 3-Channel PC Power Supply Supervisors Product Name: CG8513 Reversion: 1.00 Reversion Date: April 26, 2010 Page: 6 Pages Issue Date: 2010/05/14 April 26, 2010 – Rev. 1.00 CG8513 3-Channel PC Power Supply Supervisors Description The CG8513 is a PC switching power supply monitor with minimum external components. It provides protection circuits, power-good output (PGO), fault protection output (FPOB) and on/off control (PSONB). The over-voltage protection (OVP) monitors 3.3V, 5V and 12V (12V supplies voltage detects via VDD pin). The under-voltage protection (UVP) monitors 3.3V and 5V. When an OV or UV condition is detected, the fault protection output (FPOB) is latched high and the power good output (PGO) go low. PSONB from low to high resets the latch. When OV, UV and PGI are all right, the power good output (PGO) will be issue. A built-in 4ms delay and 38ms debounce for PSONB turn off FPOB.
