BQ79616PAPRQ1

Battery Management Overview

The BQ79616PAPRQ1 is an automotive-grade, 16-series precision battery monitor, balancer, and integrated protector designed for high-voltage battery management systems in hybrid electric vehicles (HEVs) and electric vehicles (EVs). It operates within a supply voltage range of 9 V to 80 V and supports cell balancing currents up to 240 mA. The device features a 64-pin HTQFP package with an operating temperature range from -40°C to +125°C.

Battery Management Feature Summary

• ASIL-D compliant hardware protection for overvoltage, undervoltage, overtemperature, and undertemperature conditions
• Integrated autonomous cell balancing with automatic thermal pause and resume control
• Isolated bidirectional daisy-chain communication supporting ring architecture for stack redundancy
• High-precision voltage measurement capability with configurable post-ADC digital low-pass filters

Battery Management Applications

• Hybrid electric vehicle (HEV) powertrain battery management systems
• Electric vehicle (EV) propulsion battery packs
• Energy storage system battery modules requiring high reliability

Battery Management Procurement Notes

Verify the specific suffix 'PAPRQ1' against the official Texas Instruments datasheet to confirm the HTQFP-64 package and reel packaging configuration. Ensure the component meets AEC-Q100 Grade 1 requirements for your target ambient temperature range. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability.

Battery Management Selection Notes

Select this component when designing systems requiring ASIL-D safety integrity levels for integrated protection functions. It is suitable for applications needing pin-to-pin compatibility with other devices in the BQ7961x family, such as the BQ79614 or BQ79612, to facilitate hardware reuse across different platform architectures.

Battery Management Part Context

This device belongs to the BQ7961x-Q1 series of automotive battery monitors. It shares a common footprint and software interface with the 14-series (BQ79614) and 12-series (BQ79612) variants, allowing for flexible design scaling while maintaining consistent integration strategies for stacked monitoring architectures.

Battery Management Replacement Considerations

Compatible substitutes include BQ79614PAPRQ1 and BQ79612PAPRQ1, which offer pin-to-pin compatibility with fewer monitored cells. These alternatives support similar software and hardware designs but differ in channel count.
