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
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.
