LC9018 Low Voltage Detector With Built-in Delay Circuit DESCRIPTION FEATURES LC9018 is a series of high precision voltage High-precision detection voltage: 2% detector with ultra-low current consumption Detection voltage: 2.63V and 2.93V (4.5uA typ. at Vin=3.0V) and a built-in delay (customized other voltages) circuit. It can work at very low voltage, which Built-in power on reset delay time circuit: makes it perfect for system reset. Refer to selection guide Operating voltage range: 1.2V~6V LC9018 is composed of high precision voltage Ultra-low current consumption: reference, comparator, delay circuit, output 4.5uA typ. (at Vin=3.0V) driver and resistor array. Internally preset detect Two output forms: CMOS (active low) and N- voltage has a low temperature drift and requires channel open-drain (active low) no external trimming. APPLICATIONS Two type of output, CMOS and N-channel open- drain are available. Power monitor for portable equipment such as PDA, DSC, mobile phone, notebook, MP3 LC9018 is available in TSOT-23 package which is CPU and logic circuit reset Pb free.
