LMC6953 - PCI Local Bus Power Supervisor

Description

The LMC6953 is a voltage supervisory chip designed to meet PCI (Peripheral Component Interconnect) Specifications Revision 2.1.

It monitors 5V and 3.3V power supplies.

In cases of power-up, power-down, brown-out, power failure and manual reset interrupt, the LMC6953 provides an active low reset.

Features

1.
2 Compliant to PCI Specifications Revision 2.1.
