WT7579
WT7579 is a switching power supply supervisor which monitors VX, V33, V5, V12A, V12B,V12C and V12D input voltage level The protections include Over Voltage Protection (OVP),Under Voltage Protection (UVP), Over Current Protection (OCP), External Voltage Protection(VX), and Under Voltage Lockout (UVLO). When fault condition is detected, PGO is asserted to LOW and FPOB latched HIGH.
