The BQ20Z75DBT-V180 is a member of the Battery Management System (BMS) product line from Texas Instruments. The BQ20Z75DBT-V180 is designed for intelligent battery management applications, such as direct-to-battery charge controllers, battery over-voltage protection, and multi-cell battery monitoring. It is ideal for applications that require remote diagnostics, such as those found in medical, transportation and remote power applications. BQ20Z75DBT-V180 is a 5-pin dual-cell Battery Protection IC (BPIC).

Application Field of BQ20Z75DBT-V180

The BQ20Z75DBT-V180 can be used in applications such as medical equipment, transportation, and remote power systems. It provides a high level of protection and safety for batteries used in these applications. It offers overvoltage protection to guard against the possibility of the voltage from an external source exceeding the battery’s maximum rated voltage, as well as overcharge protection to avoid excessive charge currents. In addition, it has protection against over-discharge and an integrated NTC temperature sensor for monitoring battery temperature. The BQ20Z75DBT-V180 also has additional features such as communication interfaces for remote monitoring of the battery status, or for triggering an alert when the battery reaches a certain level or temperature.

Working Principle of BQ20Z75DBT-V180

The BQ20Z75DBT-V180 is a dual-cell protection IC (BPIC). It works by monitoring and managing the charge current, voltage, and temperature of two separate cell packs. Each cell pack is individually monitored by a separate internal sense circuit. When the voltage of either cell pack reaches its upper or lower threshold, an alarm is triggered. This alarm can be used to warn against potential over-discharge events. The BQ20Z75DBT-V180 also integrates an NTC thermistor which can be used to detect the temperature of each cell pack. This feature helps to protect both cells from thermal runaway. The device also has additional features such as a serial communication interface for monitoring or controlling the device over a distance, or for triggering an external alert.

The BQ20Z75DBT-V180 is typically used in battery management systems, as it is able to monitor and protect multiple battery cells from overvoltage, overcharge, overdischarge, and temperature events. It is also capable of providing remote control and diagnostics of the battery through its communication interface. The BQ20Z75DBT-V180 can be used in applications such as medical equipment, transportation systems, and remote power systems.
