Description and Introduction

Power Minder? IC The BQ2018SN is a battery gas gauge IC manufactured by BQ (Benchmarq). It is designed for monitoring and reporting the charge status of rechargeable battery packs. Key specifications include:

- **Function**: Monitors battery voltage, current, and temperature to provide accurate charge status.
- **Communication Interface**: Uses HDQ (High-Speed Data Transfer) protocol for communication with the host system.
- **Voltage Range**: Typically supports battery packs with a voltage range of 2.5V to 4.5V per cell.
- **Current Measurement**: Integrates a sense resistor for current measurement.
- **Temperature Monitoring**: Includes inputs for external temperature sensing.
- **Memory**: Non-volatile memory for storing battery parameters and usage data.
- **Package**: Available in an 8-pin SOIC package.

This IC is commonly used in portable electronic devices for battery management.
