The LP3470 device is a micropower voltage supervisory circuit designed to monitor voltages within 1% of reset threshold over temperature. It provides maximum adjustability for power-on-reset (POR) and supervisory functions.

The LP3470 asserts a reset signal whenever the V_CC supply voltage falls below a reset threshold. The reset time-out period is adjustable using an external capacitor. Reset remains asserted for an interval (programmed by an external capacitor) after V_CC has risen above the threshold voltage.

For information on available reset threshold voltage options, see Mechanical, Packaging, and Orderable Information.
