This brown-out protection circuit employs
Microchip Technology’s MCP809
microcontroller supervisor. The MCP8XX and
MCP1XX families of supervisors provide
push-pull and open collector outputs with
both high and low active Reset pins. There
are 7 different trip point selections to
accommodate 5V and 3V systems.
