TS831-3ID

TS831-3ID Description

The TS831-3ID from STMicroelectronics is a single-channel voltage supervisor IC designed for precision monitoring of power supply voltages in electronic systems. Housed in an 8-pin SO package, this surface-mount device ensures reliable operation with a 2.71V threshold voltage and a 20µs typical response time for reset signaling. Its open-drain/open-collector output provides flexibility for interfacing with various logic levels, while the active-low reset function guarantees proper system initialization. Although marked as obsolete, the TS831-3ID remains a robust choice for legacy designs, offering ROHS3 compliance and REACH unaffected status for environmental safety.
