SP809/810, 3 Pin Microprocessor Supervisor Circuit
Copyright 2004 Sipex Corporation
3 Pin Microprocessor Supervisor Circuit
SP809 / SP810
DESCRIPTION
FEATURES
■ Ultra Low Supply Current 1
A (typ.)
■ Guaranteed Reset valid to VCC = 0.9V
■ 140 ms Min. Power-On Reset Pulse Width
■ Internally Fixed Threshold 2.3V, 2.6V, 2.9V,
3.1V, 4.0V, 4.4V, 4.6V
■ Tight Voltage Threshold Tolerance: 1.5%
■ Offered in a 3 Pin SOT-23 Package
The SP809/SP810 are low power microprocessor (
P) supervisory circuits used to monitor
power supplies in
P and digital systems. They provide applications with benefits of circuit
reliability and low cost by eliminating external components. If the V
CC supply voltage falls below
preset threshold then a reset signal is asserted for at least 140ms after V
CC has risen above the
reset threshold. Both the SP809 and SP810 were designed with a reset comparator to help
identify invalid signals, which last less than 140ms. The only difference between them is that they
have an active-low RESET output and active-high RESET output, respectively. Low supply
current (1
A) makes SP809/SP810 ideal for portable equipment. The devices are available in
3 pin SOT-23 package.
