CG8525
4-Channel PC Power Supply Supervisors with OCP
Description
The CG8525 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) and under-voltage protection (UVP) monitors V33, V5, V12A and V12B. The
over-current protection (OCP) monitors V33&I33, V5&I5, V12A&I12A /I12AB and V12B&I12B/I12AB. When an OV
or UV or OC 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, OC 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.
