Processor Supervisor 2.94V 2.9V 4-Pin SOT-143 T/R

The series are designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments, and a debounced manual reset input. This device performs a single function: it asserts a reset signal whenever the VCC supply voltage falls below a preset threshold or whenever manual reset is asserted. Reset remains asserted for an internally programmed interval (reset timeout period) after VCC has risen above the reset threshold or manual reset is deasserted. The PT7M6315USxx are open-drain RESET output. They can be pulled up to a voltage higher than VCC. The serials come with factory-trimmed reset threshold voltages in 100mV increments from 1.8V to 5V. Preset timeout periods of 200ms (typ.) for PT7M6315USxxD3, 1570ms (typ.) for PT7M6315USxxD4, and 26ms for PT7M6315USxxD2 are available.
