A4809
SUPERVISOR (RESET IC)
ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE
DETECTOR WITH DELAY CIRCUIT
DESCRIPTION
FEATURES
A4809 is a series of high precision voltage
detector with ultra low current consumption
(500nA typ. at VDD=VTH+1V) and a built-in delay
circuit. It can work at very low voltage, which
makes it perfect for system reset.
A4809 is composed of high precision voltage
reference, comparator, 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: ±2%
Detection Voltage: 1.6V~5.0V (in 0.1V steps)
Built-in Power on Reset Delay Time circuit:
Refer to Selection Guide
Operating Voltage range: 1.0V~6.0V
Ultra-low current consumption: 0.9uA typ.
(at VDD=3V)
Two Output forms: CMOS and N-channel
open-drain (Active Low)
Available in SOT-23 and SOT-23S packages
APPLICATION
A4809 is available in SOT-23 and SOT-23S
packages.
