LC709201F

Ordering number : ENA2031 LC709201F CMOS IC Battery Monitor IC http://onsemi.com Overview The LC709201F is an IC that measures the remaining power level of 1-cell lithium-ion secondary batteries by monitoring the battery voltage without an external sense resistor, and detects the remaining battery power level by current prediction. It monitors the battery voltage and realizes a function that precisely measures the remaining battery charge. In addition, the IC realizes the function for calculating the remaining battery power level even more accurately by utilizing a temperature correction function that makes use of the temperature input from a thermistor. Features Accuracy of remaining battery power level measurement Accuracy of ±5% during discharging from 100% to 0% (at an ambient operating temperature of 0°C to 50°C) Measurement of remaining battery power level The remaining power level is measured four times a second and calculated with each measurement undertaken. Interface I2Cbus, communication in slave mode up to 100kHz supported Ports I2C-bus communication pin Battery temperature reading control pin Analog voltage input pin for battery temperature Reset pin TEST pin Power supply pin 2 (SDA, SCL) 1 (TSW) 1 (TSENSE) 1 (RESB) 1 (TEST) 2 (VSS, VDD) Package form MFP10S (225 mil): LC709201FM-01/02/03 VCT16 (2.6×2.6): LC709201FRD-01/02/03 Semiconductor Components Industries, LLC, 2013 May, 2013 Ver.1.5 32812HKIM 20120307-S00004 No.A2031-1...
