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. RESET holds low for 100 ms after both 5V and
3.3V powers recover, or after manual reset signal returns to
high state. The external capacitor on pin 8 adjusts the reset
delay.
