EST.7627A
4-Channel PC Power Supply Supervisors with OCP
Description
The EST7627A 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 and V12B&I12B. The VX pin provides an extra
protection function. When an OV, UV, OC or VX 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, VX and
PGI are all right, the power good output (PGO) will be issue. A built-in 4ms delay and 38ms debounce for PSONB

FeaturesIFor Detector and Mixer ApplicationsILow Capacitance for Usage Beyond 40 GHzIZBD and Low Barrier DesignsIP-Type and N-Type JunctionsILarge Bond Pad Chip Design
DescriptionAlpha’s product line of silicon Schottky diode chips areintended for use as detector and mixer devices in hybridintegrated circuits at frequencies from below 100 MHz tohigher than 40 GHz.Alpha’s “Universal Chip”designfeatures a 4 mil diameter bond pad that is offset from thesemiconductor junction preventing damage to the activejunction as a result of wire bonding.As power-sensing detectors, these Schottky diode chipsall have the same voltage sensitivity so long as the outputvideo impedance is much higher than the videoresistance of the diode.Figure 1 shows the expecteddetected voltage sensitivity as a function of RF sourceimpedance in an untuned circuit.Note that sensitivity issubstantially increased by transforming the sourceimpedance from 50 Ωto higher values.Maximumsensitivity occurs when the source impedance equals the
