DS1812-15

Supervisors Overview

The DS1812-15 is a microprocessor reset circuit designed for +5V digital systems. It monitors the VCC supply voltage and asserts a reset signal whenever the voltage declines below a preset threshold, ensuring system reliability. The device features an active-high push-pull RESET output and includes an internal pullup resistor to VCC. It guarantees correct logic state output down to +1V and ignores fast transients on VCC through a dedicated reset comparator.
