PMIC - Battery Chargers are the key components of any electronic device, helping to keep the battery in check and providing optimum performance. The BQ2002DSNTRG4 is a PMIC - Battery Charger designed for automotive applications and designed to meet the latest requirements for certified designs in modern vehicles.

The BQ2002DSNTRG4 is a DC/DC Charger Converter that provides a high-efficiency, low-noise, low-power solution and a unique approach to extending battery life. The device includes an integrated power conversion circuit and an overvoltage protector. The power conversion circuit converts a low voltage input (10V to 16V) to an output voltage that can be adjusted up to 21V. The integrated overvoltage protector provides an overvoltage threshold of 22V, with an adjustable dead time. This device is designed to provide up to 100A charging performance in a small form factor.

The BQ2002DSNTRG4 provides two different charging modes, a constant current mode and a constant voltage mode. The constant current mode is ideal for fast charging applications, as it is able to support up to 100A of charging current. The constant voltage mode is suitable for battery maintenance or slow charging applications, as it is able to accurately adjust the output voltage to ensure a safe and stable charging performance. Both modes can be programmed with an external external input, ensuring precise control of charge parameters.

The BQ2002DSNTRG4 has a unique safety feature, the Fault-active-low, which protects the battery from overcharging and over-discharging. If the device detects a fault, it will shut down the charging current and enter a low power state, protecting the battery from overcharging and other potential issues. The device also provides high impedance discharge protection, preventing any accidental discharge of the battery.

The BQ2002DSNTRG4 is easily integrated into designs, with a low profile package (22 x 14 mm) and a wide range of operating temperatures (-40 to +125°C). The device includes an on-chip voltage detector and thermal protection so that the device can be connected to both a 5V or a 12V system. This ensures that the device can be integrated into a wide range of applications.

In addition, the BQ2002DSNTRG4 also offers complete protection for the battery. The integrated overvoltage protection ensures that the battery is protected from overcharging and ensures that the battery life is extended. The integrated undervoltage protection ensures that the battery is also protected from overdischarge and that the battery is protected from any other potential issues. The device also includes a soft-start function to enable gentle charging of the battery.

The BQ2002DSNTRG4 makes an excellent choice for automotive applications, providing a reliable, efficient, and cost-effective solution for the charging of batteries. The device is designed for easy integration, with a wide range of operating temperatures, and a low profile package, making it an ideal choice for any application.
