ACE301
Technology
High-precision Low Voltage Detector
Description
ACE301 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at
Vdd=3.0V). It can work at very low voltage, which makes it perfect for system reset.
ACE301 is composed of high precision voltage reference, comparator, 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.
ACE301 is available in SOT-89-3, SOT-23-3 TO-92, SOT23-5, packages which is Pb free.
Features
• High-precision detection Voltage： ±2%
• Detection Voltage：0.9V~6.0V (in 0.1V steps)
• Precise hysteresis：4% typ.
• 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
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
