BQ79616PAPRQ1 Battery Monitor Multi-function Controller IC
TheBQ79616PAPRQ1 is a functional safety-compliant automotive 16-series battery monitor, balancer, and integrated hardware protector from Texas Instruments, designed for high-voltage battery management systems in hybrid and electric vehicles. Housed in a robust 64-pin HTQFP package measuring 10mm × 10mm, this device supports 6 to 16 series-connected lithium-ion cells with ±1.5mV ADC accuracy and can measure all cell voltages within 128μs. Operating from a 9V to 80V supply voltage range, it features isolated differential daisy-chain communication with optional ring architecture for fault tolerance, and provides 240mA internal cell balancing current with autonomous thermal management. AEC-Q100 Grade 1 qualified with SafeTI™-26262 ASIL-D compliance for voltage/temperature/communication and ASIL-B for hardware protection, it maintains reliable performance across -40°C to +125°C.
BQ79616PAPRQ1 Applications
• Hybrid and Electric Vehicle Powertrains: High-voltage battery management systems for HEV/EV traction batteries requiring ASIL-D safety compliance
• Energy Storage Systems: Home storage, industrial/commercial ESS, and 1500V power station energy storage with scalable daisy-chain configurations
• 48V Mild Hybrid Systems: Standalone monitoring for 48V battery modules in automotive mild-hybrid architectures
• Battery Pack Management: Multi-module battery packs with up to 35 stackable devices supporting >1.5kV systems
• Grid-Scale Storage: Large-scale renewable energy storage installations requiring reliable cell-level monitoring and balancing
Alternative Compatible Battery Monitors
1. BQ79614PAPRQ1: 14-cell variant sharing identical package, software, and electrical characteristics for applications requiring reduced cell count with full platform compatibility.
2. BQ79612PAPRQ1: 12-cell version with same pinout and feature set for smaller battery modules in cost-optimized designs.
3. BQ75614PAPRQ1: Standalone 48V system monitor with integrated UART/SPI for simplified single-module designs not requiring daisy-chain expansion.
4. BQ79731-Q1: Pack-level monitor for current, contactor, and insulation resistance measurements complementing cell monitors in complete BMS architectures.
5. LTC6813HG-1: Analog Devices' 18-cell stackable monitor with isoSPI interface and 0.8mV accuracy for applications requiring higher cell counts per device.
6. MC33771CTP1AE: NXP's 14-cell Li-ion battery cell controller with CAN interface and ASIL-D support for automotive designs preferring CAN-based communication.
