Description and Introduction

1A Battery Gas Gauge with Internal Sense Resistor and Temperature/Voltage Measurement The LTC2942CDCB-1#PBF is a battery gas gauge IC manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Battery Monitoring:** Measures charge, voltage, and current for single-cell Li-Ion/Polymer batteries.  
- **Voltage Range:** 3.6V to 20V (with an external divider for higher voltages).  
- **Current Measurement:** Uses an external sense resistor (50mV full-scale range).  
- **Charge Measurement:** 14-bit ADC with ±1% accuracy.  
- **Temperature Measurement:** Internal sensor (±3°C accuracy).  
- **Communication Interface:** I²C (up to 400kHz).  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** 6-Lead DFN (2mm × 3mm).  

### **Descriptions:**  
- Monitors battery state-of-charge (SOC) with high precision.  
- Supports automatic sleep mode for low power consumption.  
- Includes an integrated sense amplifier for current measurement.  

### **Features:**  
- **Accurate Charge Tracking:** 14-bit ADC for precise SOC calculation.  
- **Wide Voltage Range:** Compatible with various battery chemistries.  
- **Low Power Operation:** Consumes minimal current in sleep mode.  
- **I²C Interface:** Allows easy communication with microcontrollers.  
- **Internal Temperature Sensor:** Monitors battery temperature.  

This IC is commonly used in portable electronics, medical devices, and energy storage systems for accurate battery monitoring.
