TPS5510D

3通道电源监控 3-CHANNEL POWER SUPPLY SUPERVISOR

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.

OVP Over Voltage Protection monitors 5 V, 3.3 V, and 12 V 12 V OV detects via VCC terminal. UVP Under 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.

The TPS5510 is characterised for operation from TJ = –40°C to 125°C junction temperature.
