TPS3807 Description
The TPS3807 family microprocessor supervisory circuits monitor system voltages as low as 1.225V. These devices assert an open-drain RSTVDD signal when the VDD voltage drops below a preset threshold. The RSTVDD output remains asserted until the VDD voltage returns above its threshold.
