ACE306
Low Voltage Detector with Built-in Delay Circuit / SSD
Description
ACE306 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at
Vdd=3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system
reset.
ACE306 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.
Features
High-precision detection Voltage：2%
Detection Voltage：0.9V~6.0V (in 0.1V steps)
Built-in Power on Reset Delay Time circuit::Refer to Selection Guide
Operating Voltage range：0.7V~10V
Ultra-low current consumption：500nA typ. (at VDD＝3.0V)
Two Output forms
：CMOS
and N-channel open-drain (Active Low)
