description

The TPS5510 is designed to minimize external components of personal computer switching power supply

systems. It provides protection circuits, power good indicator, fault protection output (FPO), and a PSON control.

Voltage Protection) monitors 5 V and 3.3 V. When an OV or UV condition is detected, the PGO (power good

output) is asserted low and FPO is latched high. PSON from low to high resets the protection latch. UVP function

will be enabled 75 ms after PSON is set low and debounced.

Power good feature monitors PGI, 5 V and 3.3 V and issues a power good signal when they are ready.
