BQ79616PAPRQ1 概要
A battery monitor IC is a specialized integrated circuit that measures the voltage of individual cells in a series lithium-ion stack. It is the core sensing element of a battery management system (BMS), which sits within the broader power-management IC hierarchy. BMS devices ensure safe and efficient battery-pack operation in electric vehicles, hybrid vehicles, and grid energy-storage systems by providing data for state-of-charge and state-of-health estimation and by triggering protective actions.
Key differentiating features include ASIL-D functional-safety compliance for ISO 26262-oriented designs, AEC-Q100 Grade 1 qualification, and integrated overvoltage, undervoltage, and overtemperature protection plus passive cell balancing. Pin-to-pin compatibility with the BQ79614-Q1 (14S) and BQ79612-Q1 (12S) variants enables hardware and software reuse across platforms with different cell counts. The integrated front-end supports simple low-voltage differential RC filters on cell input channels, reducing BOM cost versus designs that require high-voltage rated external components.
Technically, the BQ79616PAPRQ1 uses a precision ADC architecture to measure all 16 cell voltages in less than 200 microseconds, enabling real-time protection decisions during high-rate charge and discharge events. A daisy-chain communication interface supports stacking multiple devices for higher total cell counts in large packs, and the 64-pin HTQFP package exposes a thermal pad that must be soldered with adequate thermal vias to keep junction temperature within limits during continuous balancing.
Typical applications include automotive HEV/EV battery management for 16S modules, ASIL-level energy storage, and lithium-ion backup power stacks. In each case the fast total measurement time and high accuracy support real-time monitoring under demanding automotive conditions, and the shared 64-HTQFP footprint with the 14S and 12S family members enables one PCB to ship three product variants.
A key design consideration is the differential RC filter sizing on cell inputs: filter values directly affect measurement settling time and accuracy, so follow the datasheet recommendations and place the device with adequate thermal vias under the HTQFP thermal pad.

主な用途
BQ79616PAPRQ1 の用途: 6 件s: Automotive HEV/EV 16S Battery Management, Grid-Scale Energy Storage Systems (ESS), Industrial Backup Power (UPS) Battery Monitoring, E-Bike and Light Electric Vehicle 16S Packs, Battery Formation and Test Equipment, Robotics and AGV Battery Packs.
Automotive HEV/EV 16S Battery Management
The BQ79616PAPRQ1 is the core sensing element of a 16S HEV/EV battery management module, where its <200 us full-stack measurement time supports real-time OV/UV detection during high-rate charge and discharge pulses. ASIL-D compliance and AEC-Q100 Grade 1 qualification match ISO 26262-oriented traction-pack designs, and the integrated passive balancer removes the need for an external balancing IC. Placed adjacent to the cell-tap harness with differential RC filters sized per datasheet guidance, the device feeds cell voltages to the host MCU through the daisy-chain UART, simplifying HV isolation versus parallel-per-cell architectures.
おすすめ
Grid-Scale Energy Storage Systems (ESS)
For stationary lithium-ion ESS racks, the BQ79616PAPRQ1's 16S channel count fits common LFP rack voltages around 48-60 V nominal, and its ASIL-D compliance is increasingly required by utility-grade safety standards. The <200 us full-stack measurement time supports fast disconnect on cell-level faults, while the daisy-chain interface allows stacking of multiple BQ79616PAPRQ1 devices for high-voltage packs. Thermal vias under the HTQFP pad are critical because continuous balancing at high SOC can dissipate several watts per device.
おすすめ
Industrial Backup Power (UPS) Battery Monitoring
In telecom and datacenter UPS strings built from 16S lithium-ion stacks, the BQ79616PAPRQ1 provides ASIL-D-grade cell monitoring with hardware OV/UV/OT protection that can directly drive contactors without host intervention. The integrated protector function shortens the fault-to-disconnect time, which is essential for backup systems where a single cell overvoltage can cascade into thermal runaway. Use the BQ79600-Q1 to bridge the daisy-chain UART to the rack controller's isolated SPI.
おすすめ
E-Bike and Light Electric Vehicle 16S Packs
Compact 16S e-bike and light-EV packs benefit from the BQ79616PAPRQ1's small 64-HTQFP 10x10 mm footprint and integrated passive balancing, which removes the space-consuming discrete balancing resistors. AEC-Q100 Grade 1 qualification, while not required for non-automotive, gives extra margin against vibration and thermal stress on e-bike duty cycles. Pair with a host MCU running the BQ79616-Q1 reference software for rapid product development.
おすすめ
Battery Formation and Test Equipment
Cell-formation racks and end-of-line battery testers use the BQ79616PAPRQ1 to acquire high-accuracy voltage data on 16S packs under controlled charge/discharge cycles. The <200 us full-stack measurement time supports high-throughput formation lines, and ASIL-D compliance allows the same hardware to be reused in automotive-grade qualification lines. Daisy-chain multiple BQ79616PAPRQ1 devices to monitor multi-pack fixtures without extra isolators.
おすすめ
Robotics and AGV Battery Packs
Autonomous mobile robots and automated guided vehicles typically use 48-60 V 16S lithium packs where the BQ79616PAPRQ1's hardware protector ensures immediate disconnect on cell faults without depending on host software, a critical safety feature for human-collaborative environments. The 64-HTQFP package's small footprint suits space-constrained robot battery bays, and daisy-chain enables packs to be monitored in parallel. Pair with the BQ79600-Q1 bridge for isolated communication to the robot's central controller.

主な差別化要因
- Highest cell-count pin-compatible member of the BQ7961x-Q1 family in the same 64-HTQFP (PAP) footprint （vs BQ79614PAPRQ1 / BQ79612PAPRQ1)
- Integrated hardware protector plus passive balancer in a single IC （vs BQ76952PFBR (non-automotive monitor))
- True cross-brand 64-HTQFP 14S ASIL-D monitor with same package footprint family （vs L9963 (STMicroelectronics))
設計ノート
The 64-HTQFP (PAP) package relies on the exposed thermal pad for heat removal. Estimated: at continuous balancing current of 100 mA per cell across all 16 cells, internal dissipation can reach 1-2 W; provide a thermal pad land area of at least 100 mm^2 with a 4x4 thermal-via array (0.3 mm drill, 1 mm pitch) tied to an internal ground plane to keep junction below 125 C at 85 C ambient.
Per TI, place differential RC low-pass filters on each VCx cell input pin (typical 100 ohm + 100 nF). Keep filter components within 5 mm of the IC pins and route the differential traces as a coupled pair to reject common-mode noise from the HV traction pack. The HV-side resistor divider values are family-specific and must be derived against the BQ79616-Q1 datasheet, not guessed.
Do not skip the daisy-chain isolation barrier between BQ79616PAPRQ1 and the low-voltage host MCU: TI recommends the BQ79600-Q1 (or equivalent) UART-to-isolated-SPI bridge to withstand the HV transient of the traction pack. Tie the WAKE/SHUTDN lines per the datasheet power-up sequence to avoid the device latching in an undefined state on cold-crank events.
