Product Overview

The LTC2943IDD#PBF is a Multi-cell Battery Gas Gauge measures battery charge state, battery voltage, battery current and its own temperature in portable product applications. The wide input voltage range allows use with multicell batteries up to 20V. 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. The LTC2943 features programmable high and low thresholds 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 registers. It requires only a single low value sense resistor to set the measured current range.
  • Measures accumulated battery charge and discharge
  • 14-bit ADC measures voltage, current and temperature
  • 1% Voltage, current and charge accuracy
  • ±50mV Sense voltage range
  • High side sense
  • General purpose measurements for any battery chemistry and capacity
  • I²C/SMBus interface
  • Configurable alert output/charge complete input
  • <120μA Quiescent current
