More Information
The TPS312x family of voltage supervisory circuits provides voltage monitoring down to 1.2V rails and timing supervision, primarily for DSP and processor-based systems. All devices in the family monitor the power rail and assert RESET output when the power rail is under the threshold voltage target (VIT-). The threshold voltage is programmed into the device to minimize external components. Built-in hysteresis prevents false triggering. The RESET output is not valid for supply voltage (VDD) under 0.75 V. The TPS312x family includes devices with active high output for use as disable during malfunction and active low outputs for most systems where high output indicates properly functioning system.
