Pericom Semiconductor PT7M6837
The PT7M6832–6840 are microprocessor (µP) supervisory circuits used to monitor low-voltage power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +1.2V to +1.8V powered circuits. These devices assert a reset signal whenever the VCC supply voltage declines below a preset threshold or whenever manual reset (MR) is asserted.| Part No. | PT7M6837 |

DESCRIPTION
Reset remains asserted for a fixed timeout delay after VCC has risen above the reset threshold or when manual reset is deasserted.
