Watchdog Timers

For general use  |  For automotive

A watchdog timer (WDT) is a timer that monitors microcontroller (MCU) programs to see if they are out of control or have stopped operating. It constantly watches over the MCU to ensure it is operating normally.
ABLIC's watchdog timers (WDTs) are equipped with a reset function and feature selectable window or time-out modes. With the industry's top class ultra-low current consumption, our watchdog timers are ideal for monitoring systems of microcontrollers. These features make them suitable for a wide range of applications, including cordless power tools, housing equipment, and industrial equipment.
