Low Voltage Detector with Built-in Delay Circuit
Description
ACE302 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.
ACE302 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.
ACE302 is available in SOT-23-3 which is Pb free.
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)
Application
• Power monitor for portable equipment such as PDA,DSC,Mobile phone,Notebook,MP3
• CPU and Logic Circuit Reset
• Battery Checker
• Battery Back-up Circuit
• Power Failure Detector

Technology Low Voltage Detector with Built-in Delay Circuit
Function description
High precision low temperature co-efficiency reference voltage is applied to the negative input of a
comparator. Input voltage, divided by resistor array of Ra and Rb, is applied to the positive input of the
comparator. Output of the comparator passes a delay circuit and a series of buffer to drive the output
CMOS pair.
