LC709201F

Ordering number : ENA2031 LC709201F Overview CMOS IC Battery Monitor IC 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 Package form • MFP10S (225 mil): LC709201FM-01/02/03 • VCT16 (2.6×2.6): LC709201FRD-01/02/03 2 (SDA, SCL) 1 (TSW) 1 (TSENSE) 1 (RESB) 1 (TEST) 2 (VSS, VDD) Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment.
