BQ771602DPJR

Battery Management Overview

The BQ771602DPJR is a battery protection integrated circuit designed for lithium-ion and lithium-polymer battery packs. It supports configurations of two to four series-connected cells. The device operates within a supply voltage range of 3 V to 20 V and functions across an ambient temperature range of -40°C to +110°C. It utilizes an 8-WSON (3x4 mm) surface-mount package with exposed pad. The component provides overvoltage fault protection and features a low operating current of 1 µA.

Battery Management Feature Summary

• Provides overvoltage protection for multi-cell lithium-based battery architectures
• Operates with ultra-low quiescent current to minimize standby power consumption
• Supports standard I2C communication interface for configuration and monitoring

Battery Management Applications

• Portable electronic devices requiring multi-cell battery management
• Power tools utilizing lithium-ion battery packs
• Medical equipment with sealed battery systems
• Consumer electronics with compact form factor constraints

Battery Management Procurement Notes

Verify the specific suffix DPJR corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the RoHS3 compliance status meets environmental regulations for the target market. Ensure the MSL rating aligns with the facility's moisture sensitivity handling procedures during storage and soldering operations.

Battery Management Selection Notes

Select this component when designing systems requiring protection for two to four series cells without active balancing capabilities. Consider the 8-WSON package dimensions for PCB layout constraints. Evaluate the thermal performance requirements given the exposed pad design and specified operating temperature range for the intended application environment.

Battery Management Part Context

This part belongs to the BQ7716xx family of battery protection ICs from Texas Instruments. It shares functional similarities with variants like the BQ771601 and BQ771612, differing primarily in specific pinout configurations or internal threshold settings defined by the datasheet. The family targets cost-sensitive applications needing reliable cell monitoring.

Battery Management Replacement Considerations

Direct substitutes include other members of the BQ7716xx series such as the BQ771601DPJR or BQ771612DPJR, provided pin compatibility and electrical thresholds match the design requirements. Verify package equivalence and ensure any alternative maintains the same communication protocol support.
