The LP3470M5-4.00/NOPB is a Voltage Supervisor with open-drain output and programmable delay. The 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.
• Programmable reset time-out period using an external capacitor
• Immune to short VCC transients
• Reset valid down to VCC = 0.5V
• ±1% Reset threshold accuracy over-temperature
• 16µA Typical low quiescent current
• Green product and no Sb/Br
