PCI Local Bus Power Supervisor
General DescriptionThe LMC6953isa voltage supervisory chip designedto
meet PCI (Peripheral Component Interconnect) Specifica-
tions Revision 2.1.It monitors5V and 3.3V power supplies. casesof power-up, power-down, brown-out, power failure
and manual reset interrupt,the LMC6953 providesan active
low reset. RESET holds lowfor 100ms after both5V and
3.3V powers recover,or after manual reset signal returnsto
high state. The external capacitoronpin8 adjuststhe reset
delay.
This partis idealon PCI motherboardsor add-in cardsto
ensurethe integrityofthe entire system when thereisa fault
condition. The active low reset sets the microprocessoror
local deviceina known state.
The LMC6953 hasa built-in bandgap reference that accu-
rately determinesall the threshold voltages. The internal
reset delay circuitry eliminates additional discrete compo-
nents.
Features Compliantto PCI specifications revision 2.1. Under and over voltage detectorsfor5V and 3.3V Power failure detection (5V falling under 3.3Vby
300 mV max) Manual reset inputpin Guaranteed RESET assertionat VDD= 1.5V Integrated reset delay circuitry Open drain output Adjustable reset delay Response timefor over and under voltage detection:
490ns Max Power failure response time: 90ns Max Requires minimal external components
