The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.
350-nA nano power voltage supervisor with programmable delay, MR pin and up to 10-V VIN.
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
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 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.
