The wide input voltage range allows use with multicell batteries up to 60V. A precision coulomb counter integrates current through a sense resistor between the battery’s positive terminal and the load or charger. Voltage, current and temperature are measured with an internal 14-bit No Latency ΔΣ™ ADC. The measurements are stored in internal registers accessible via the onboard I2C\/SMBus Interface.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eThe LTC2944 features programmable high and low thresh-olds for all four measured quantities. If a programmed threshold is exceeded, the device communicates an alert using either the SMBus alert protocol or by setting a flag in the internal status register. The LTC2944 requires only a single low value sense resistor to set the measured current range.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e​\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eParameter:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eMeasured accumulated battery charge and discharge\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e3.6V to 60V operating range for multi-cell applications\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eMaximum temperature and current conversion time: 8MS\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eMaximum voltage conversion time: 48MS\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eTemperature sensing range: 236.85 degree\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eVoltage, current and charging accuracy: 1%\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eDetection voltage range: ±50MV\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eI2C \/ SMBUS interface configurable alarm output \/ charge completion input\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eQuiescent current: \u0026lt; 150MA\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eIIC communication frequency: 400 ~ 900KHZ\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\n\u003cspan style=\"font-size:14px;\"\u003e14-bit zero-delay ADC is responsible for measuring voltage, current 12 bits) and temperature (11 bits)\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eIIC hardware address:\u003c\/strong\u003e\u003c\/span\u003e 1100100x (x is the read\/write direction control bit);\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e- VCC: The pull-up resistor common terminal of the three communication ports on the board should be connected to the VCC of the external controller;\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e- ALCC: alarm output or charge completion input, default alarm mode;\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e- S+: SENSE + chip power supply terminal and induced current positive input terminal;\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e- S-: Inductive current negative input terminal and positive terminal of the tested battery power supply;\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e- SDA: IIC data signal line;\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e- SCL: IIC clock signal line\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003ePackage includes:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e3 x Board with pin\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Banggood","offers":[{"title":"Default Title","offer_id":31968912900234,"sku":"U2I-BG-1490943","price":7828.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/79945c79-2ae2-4485-91e2-8219fb2e3866.jpg?v=1580171334","url":"https:\/\/shop2india.com\/products\/3pcs-cjmcu-294-ltc2944-battery-temperature-measuring-module-60v-voltage-and-current-measurement-meter_1490943","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
