Voltage supervisor and reset ICs: tips, tricks and basics
We depend on the reliable and safe operation of countless electronics all around. To ensure that these systems operate correctly in the diverse and sometimes harsh environments found in industrial and automotive applications, system designers must incorporate accurate and redundant monitoring of the critical power supplies that power the systems’ processing and signalchain blocks.
A voltage supervisor (also known as a reset integrated circuit [IC]) is a type of voltage monitor that monitors a system’s power supply. Voltage supervisors are often used with processors, voltage regulators and sequencers – in general, where voltage or current sensing is required.
Supervisors monitor voltage rails to ensure power on, detect faults and communicate with embedded processors to ensure system health. Safety integrity levels (SILs) and automotive SILs (ASILs) in industrial and automotive applications require highly accurate voltage monitoring.
The Texas Instruments (TI) supervisors portfolio includes low-power, small-size, high-accuracy, watchdog timer, wide input voltage, multichannel and push-button reset ICs to help engineers meet design requirements.
