WT7542

The WT7542 is designed for LCD TV power supervisor application, it provides fault protection latch (FPOB) and a protection detector function (PSONB) control. The Over Voltage Protection (OVP) monitors VS12 and VS24 input voltage level. The Over Current Protection (OCP) monitors IS12 and IS24 input current sense. Especially Short Circuit Protection (SCP) monitors VS12 and VS24 waveforms When OVP or OCP or SCP detected the fault voltage level, it will latch the fault condition and let FPOB pin goes to Hi-Z. Latch is reset only when PSON goes to low or VCC lower than UVLO voltage.
