by an internal voltage divider.

The TPS3123-xx and TPS3125-xx devices incorporate a manual reset input, MR. A low level at MR causes

RESET to become active. The TPS3124-xx devices do not have the input MR, but include a high-level output

RESET same as the TPS3125-xx devices. In addition the TPS3123-xx and TPS3124-xx have a watchdog timer

that need to be triggered periodically by a positive or negative transition at WDI. When the supervising system

The circuits are available in a 5-pin SOT23-5 package. The TPS3123, TPS3124, TPS3125 devices are

characterized for operation over a temperature range of – 40

°C to 85°C.
