Working Principle of SN72PV195DBTR

The SN72PV195DBTR consists of three major blocks: a battery balancer, a battery monitor and a power switch. The battery balancer is responsible for monitoring the charging/discharging current, and for scaling the charge capacity of each cell in multi-cell battery configurations. The battery monitor block is responsible for monitoring the voltage of each cell, and for providing over-voltage and under-voltage fault detection. The power switch implements the ON/OFF control of the charging and discharging paths, as well as low power operating modes.

The SN72PV195DBTR uses a predictive cell-balancing algorithm, which autonomously control the charge capacities of each cells and allows for a non-uniform distribution of charge. This balancing logic also provides a scalable solution for battery-powered systems, helping to improve total system efficiency. The SN72PV195DBTR also features a programmable current-limit, which allows the system to be configured with a wide range of charge/discharge conditions. The chip also includes an advanced multi-level safety protection to guard against overloads, overcharge, over-temperature and reverse current conditions, ensuring that the system is reliable and safe to operate.

The SN72PV195DBTR also provides programmable battery charge/discharge control functions, which can be configured to support a range of applications and operating modes. The chip has a high current capacity, and can be used to charge and discharge batteries at high rates, while providing a fast response time in transient conditions. Finally, the chip includes a wide input voltage range and accepts an input voltage of up to 26V, making it an ideal solution for automotive systems.
