LP3470A
- Pin-to-pin compatible with LP3470
- 5-Pin SOT-23 package
- Open-drain RESET output
- Programmable reset time-out period using an external capacitor
- Immune to short VCC transients
- ±1% Reset threshold accuracy (typical)
- Ultra-low quiescent current (0.3 µA typical)
- RESET valid down to VCC = 0.95 V
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.
