Power Management IC (PMIC) is a kind of integrated circuit designed to manage power supply in electronic systems. In particular, Battery Management (BM) systems are responsible for the safe and efficient operation of electronic systems powered by batteries, such as mobile phones, laptop computers, and other devices. The BQ20Z90DBTR-V150 is a battery management solution developed by Texas Instruments to provide reliable and efficient control of Li-ion and Li-po batteries.

The device is designed as an integrated package, including a digital controller, high side switches and a range of built-in safety features. It has the capability to measure and control numerous variables, such as current, temperature, voltage, and battery capacity. Additionally, the device incorporates an Advanced Encryption Standard (AES) accelerator for high-level security. It is an extension of the BQ20Z90 battery management family and is ideal for applications such as energy-related products, wireless headsets, and personal medical devices.

The BQ20Z90DBTR-V150 uses a combined programmable logic and controller architecture to provide comprehensive and efficient power management. The built-in 16-bit processor contains both hardware and interface logic to facilitate efficient operation. It also offers a series of protection features, such as over-voltage, over-temperature, and over-charge protection, making it a robust and reliable solution. The device also supports several power management modes, such as full-cycle, under-voltage, and sleep. All these features make the BQ20Z90DBTR-V150 an ideal choice for managing power in a range of consumer and industrial applications.

The working principle behind the BQ20Z90DBTR-V150 is fairly simple. It uses digital logic to sample the battery voltage and current and then send a signal to the controller. Depending on the power-management mode, the controller then instructs the SIOV (Selective Input/Output Viewer) to control the charging and discharging of the battery. The SIOV is the interface between the controller, voltage supervisor, and high side switches. The SIOV enables the device to monitor the system\'s current, voltage, and temperature, as well as to control its charging and discharging.

One of the main benefits of the BQ20Z90DBTR-V150 is its low power consumption, which allows it to be used in a variety of battery-powered applications. Another advantage is its flexibility, as it can be customized to meet specific application requirements. The device also features a wide operating temperature range, making it suitable for both indoor and outdoor applications. Additionally, the device is designed to be highly reliable, offering robust protection in the event of a fault.

In conclusion, the BQ20Z90DBTR-V150 is an integrated battery management solution that provides comprehensive control of Li-ion and Li-po batteries. It has a built-in processor and a range of protection features, as well as additional features for enhanced security and flexibility. The device is ideal for applications such as energy-related products, wireless headsets, and personal medical devices. Finally, its low power consumption, wide operating temperature range, and high reliability make it a great choice for power management in a range of applications.
