Description

The LP3470A device is a micropower voltage supervisory circuit designed to monitor voltages within 1% of reset threshold overtemperature and is pin-to-pin compatible with existing TI device LP3470. The LP3470A device provides accurate, nano-power voltage monitoring with programmable delay. The LP3470A asserts a reset signal whenever the VCC 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 VCC has risen above the threshold voltage plus hysteresis. For information on available reset threshold voltage options, seeMechanical, Packaging, and Orderable Information.
