LC709201F 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 de tects 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 func tion 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 s econd and calculated with eac h measurement undertaken. ? interface ? i 2 cbus, communication in slave mode up to 100khz supported ? ports ? i 2 c-bus communication pin 2 (sda, scl) ? battery temperature reading control pin 1 (tsw) ? analog voltage input pin for battery temperature 1 (tsense) ? reset pin 1 (resb) ? test pin 1 (test) ? power supply pin 2 (v ss , v dd ) ? package form ? mfp10s (225 mil): LC709201Fm-01/02/03 ? vct16 (2.62.6): LC709201Frd-01/02/03 ordering number : ena2031 cmos ic battery monitor ic
