LP3470
Tiny Power On Reset Circuit
General Description
The LP3470 is a micropower CMOS voltage supervisory
circuit designed to monitor power supplies in microprocessor
(µP) and other digital systems. It provides maximum adjust-
ability for power-on-reset (POR) and supervisory functions. It
is available in the following six standard reset threshold
voltage (V
4.38V, and 4.63V. If other voltage options between 2.4V and
5.0V are desired please contact your National Semiconduc-
tor representative.
The LP3470 asserts a reset signal whenever the V
voltage falls below a reset threshold. The reset time-out
period is adjustable using an external capacitor. Reset re-
mains asserted for an interval (programmed by an external
capacitor) after V
The device is available in the tiny SOT23-5 package.
