A4809
DESCRIPTION
FEATURES
A4809 is a series of high precision voltage detector with ultra-low current consumption (4.5u A typ. at VIN=3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system reset. A4809 is posed of high precision voltage reference, parator, delay circuit, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming. Two type of output, CMOS and N-channel open-drain are available.
- High-Precision Detection Voltage: ±3%
