BAT854SWF is a diode-arrays family of devices suitable for automated assembly processes. It was developed to meet the requirements of the improving power efficiency in mobile terminal applications. The rigorous design process delivers superior performance and highest reliability suitable for power ICs, especially in high-voltage and low-voltage applications.

The BAT854SWF is designed with an NAND type integrated circuit using a BiCMOS (Bipolar-CMOS) process. To ensure compact size and reliable performance, the power-handling capability of the device is divided into two parts. The first part, MOSFETs, provides adjustable current-limiting, load-current regulation, and temperature protection. The second part, diodes, provides low-impedance output protection.

BAT854SWF device is comprised of two dual N-channel MOSFETs, four 10V-rated Schottky diodes (four antibounce diodes), a low-noise regulator, a low-current-drop diode, and two capacitors. Both the MOSFETs and the Schottky diodes are integrated into a single package. This device family offers performance improvements in low-voltage and high-voltage applications when compared to discrete components.

The MOSFETs in the BAT854SWF device are designed to regulate current in the system while minimizing switching losses. Moreover, they can be used as power-switch transistors. Besides this, the device utilizes Schottky diodes with low forward voltage drop to decrease current loss in diode conduction. The low-noise regulator controls the output voltage during high-current transients.

In addition to its power-handling capabilities, this device family from STMicroelectronics also offers various protection features. Over-voltage protection prevents system damage from exceeding the safe voltage range. Over-temperature protection monitors the environment temperature and protects the device from exceeding the safe temperature range. Reverse voltage protection and under-voltage protection helps to prevent device failure in case of fault conditions.

The BAT854SWF device is suitable for a wide range of applications, most notably as power switching devices in mobile terminal applications. For instance, it can be used in power supplies, automotive applications, telecommunication systems, and portable devices. This device family has also found applications in consumer, industrial, and medical devices.

To conclude, the BAT854SWF is an innovative device from STMicroelectronics that incorporates two dual N-channel MOSFETs and four 10V-rated Schottky diodes in a single package, which makes it suitable for high-performance, power-sensitive applications. It offers improved power efficiency, numerous protection features, and reliable operation, making it an ideal choice for many applications.
