BQ79716B-Q1 概要
A battery monitor is a specialized analog front-end (AFE) IC that measures individual cell voltages and temperatures in a battery pack, and communicates the data to a microcontroller for state-of-charge (SoC) and state-of-health (SoH) estimation. In the hierarchy, the battery monitor sits as the cell supervision AFE, converting analog cell voltages into digital data via an internal ADC.
Key features include support for up to 16S battery modules, pin-to-pin compatibility with other channel options in the same package family, and ASIL-D functional safety compliance. The device also offers a temperature grade up to +125C ambient, robust ESD protection, and the ability to reuse established software and hardware across different platforms.
Technically, the BQ79716B-Q1 employs a state-of-the-art ADC architecture to achieve high measurement accuracy. It supports daisy-chained communication in large battery stacks, enabling scalability to 96S+ systems. The integrated balancer allows redistribution of charge across cells, improving battery pack longevity. However, specific electrical parameters such as supply voltage range and communication protocol are not specified in the current data.
Typical applications include battery management in electric vehicles (EV), hybrid electric vehicles (HEV), energy storage systems, industrial battery backup, and electric two-wheelers. The device's ASIL-D compliance makes it suitable for functional safety-critical systems where cell monitoring is mandatory.
Designers should ensure proper decoupling capacitors and high-voltage isolation for the daisy-chain interface. The HTSSOP-20 (PAP) package requires a thermal pad connection to ground for heat dissipation. Reference designs from TI (e.g., EVM) can guide layout for high-voltage BMS applications.

設計ノート
For high-voltage BMS applications, the BQ79716B-Q1's HTSSOP-20 (PAP) package requires a thermal pad connected to ground. Place a 0.1uF decoupling capacitor close to each VDD pin and a 10uF bulk capacitor. The daisy-chain interface should be routed with proper isolation to prevent noise coupling.
Do not exceed the maximum cell voltage rating. Ensure the ADC input filters are properly sized to reduce noise. When using the integrated balancer, confirm the balancing current does not cause excessive thermal rise.
The HTSSOP-20 has a thermal pad that must be soldered to a large copper region for heat dissipation. In a 16S BMS, the device's power dissipation is low, but balancing currents can produce heat. Use vias to the ground plane for thermal relief.
