LP3470A Ultra-Low Power Voltage Supervisor

Texas Instruments LP3470A Ultra-Low Power Voltage Supervisor is designed to monitor voltages within 1% of reset threshold overtemperature. This device is pin-to-pin compatible with the existing TI LP3470. The LP3470A device provides accurate, nano-power voltage monitoring with programmable delay. The device 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. The reset remains asserted for an interval (programmed by an external capacitor) after VCC has risen above the threshold voltage plus hysteresis.
