WT7612T

WT7612T is a switching power supply supervisor which monitors twochannelsof +12VA and +12VBoutputs.The protections include Over Voltage Protection (OVP), UnderVoltage Protection (UVP), Over Current Protection (OCP), VXand VCC Under Voltage Lockout (UVLO). When +12VA or +12VB OVfault condition is detected, FPOB1latched LOW.When +12VA or +12VB OC or VX or UVfault condition is detected, FPOB2 latched LOW.It also provides BE signal for burst mode detected.
