Description

The TPV710 is a watchdog timer circuit which prevents

system failures caused by certain types of hardware errors

or software errors.

The TPV710 watchdog timer circuit has an input, WDI,

and output WDO. The input is used to clear the

internal watchdog timer periodically within the specified

timeout period tWD. While the system operates correctly, it

periodically toggles the watchdog input, WDI. If the system

fails, the watchdog timer is not reset, and the watchdog

output, WDO, is asserted.

The TPV710 has an enable input, EN, which can enable or

disable the watchdog functionality. The EN is connected to

the internal pull-down resistor. The device is enabled if the

EN pin is left floating.

The TPV710 is available in SOT23-5 package. The

operation temperature range is -40℃ to 125℃.
