Overview for supervisor and reset ICs
TI provides a wide portfolio of supervisors and reset ICs, including watchdog timers, push-button ICs, voltage detectors, and fixed and programmable delay time supervisors. Also known as voltage monitors or reset ICs, these devices monitor system health. These devices pack integration with the right combination of features to provide flexibility for customers across almost any application, including automotive cameras, avionics, servers, notebooks, electricity meters, handsets, tablets and more.
Browse by supervisor type
Coupling a voltage supervisor with a watchdog timer allows supply voltage monitoring of the processor as well as internal fault detection.
Detect overvoltage fault events in addition to undervoltage fault events to alert a system if a voltage rail deviated from its permissible tolerance.
A push-button reset IC can monitor user presses and provides a reset after a given time period has been met.
Browse by supervisor feature
Offers built-in delay time for supervisor before notifying that monitored voltage has returned to safe level.
Offers flexibility of an adjustable delay time for supervisor before notifying that monitored voltage has returned to safe level.
For voltage rails 12V or greater, TI's family of wide-input voltage detectors can both operate from and monitor 12-V, 15-V, 24-V, 36-V rails and more.
TI's family of small-size, low-power supervisors help address PCB size constraints, improve system efficiency and extend battery life.
Latching a voltage supervisor (reset IC)
Learn how to latch the output of the supervisor to keep it in the fault state even when the monitored voltage rail rises back to a normal operating condition.
Latching a watchdog timer
Learn how to latch the output of the watchdog to keep it in the fault event when the watchdog input begins to pulsate again.
Mitigating voltage glitch on the output
Learn how to mitigate an indeterminate output on startup. Voltage supervisors require a minimum voltage on the supply pin before the output can be sampled correctly.
Optimizing resistor dividers at a comparator input
Learn about the tradeoffs to consider when selecting the actual resistor values for the voltage divider used at the input of a supervisor.
