R7510A

® R7510A PC Power Supply Supervisor General Description R7510A is a supervisor IC especially designed for PC power supplies with 3.3V, 5V and 12V outputs. The R7510A integrates a remote ON/OFF control input (PSONB), noise de-bounce/deglitch circuits, timing-and-fault control logics, an output power good indicator (PGO), an input power good input (PGI) and full output protections which include a fault indicator (FPOB), under voltage and over voltage protections. R7510A minimizes external component count and makes the designs of power supply easier. As the PSONB receives a valid ON/OFF signal from a PC motherboard, the FPOB voltage goes low to start a poweron process. When the power-on process is completed, all of protections are enabled and the PGO voltage goes high to indicate that the output voltages are all in regulation ranges.
