SG6510X1 is a PC power supply voltage supervisor chip produced by System General Corp., with over-voltage and under-voltage protection functions, output pins include PGO and FPO, PGO is a power good signal, and FPO is a fault protection signal.
The System General SG6510X1 is an integrated circuit designed to provide voltage supervision functions for PC power supply systems. It monitors over-voltage (OVP) conditions for 3.3V, 5V, and 12V lines, as well as under-voltage sense (UVS) and protection (UVP) for the 3.3V and 5V rails to prevent damage during power fluctuations.
The device features remote on/off control via a PSON pin with programmable delays and provides fault protection outputs (FPO) that can latch or unlatch based on specific voltage thresholds. It includes open-drain outputs for Power Good (PGO) and Fault Protection Output (FPO) signals, along with noise deglitching to ensure stability against transient spikes.
