TPS3510DR +BOM

Supervisor Open Drain or Open Collector 3 Channel 8-SOIC

TPS3510DR General Description

The TPS3510/1 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 (PSON)\ control.

Overvoltage protection (OVP) monitors 3.3 V, 5 V, and 12 V (12-V signal detects via VDD pin). Undervoltage protection (UVP) monitors 3.3 V and 5 V. When an OV or UV condition is detected, the power good output (PGO) is set to low and (FPO)\ is latched high. (PSON)\ from low to high resets the protection latch. UVP function is enabled 75 ms after (PSON)\ is set low and debounced. Furthermore, there is a 2.3-ms delay (and an additional 38-ms debounce) at turnoff. There is no delay during turnon.

Power good feature monitors PGI, 3.3 V and 5 V and issues a power good signal when the output is ready.

The TPS3510/1 is characterized for operation from –40°C to 85°C.
