ACE301
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.
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 V
DD
＝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
