DEU9SBB is an integrated circuit for power electronics applications. It is a reliable and cost effective solution for power conversion, motor control, and other industrial motor applications. This article will cover the application field and working principle of the DEU9SBB integrated circuit.

Applications of DEU9SBB

The DEU9SBB has been successfully used in a variety of power electronics applications. It is most commonly used in motor control applications, specifically for three-phase brushless DC (BLDC) motor control. The device provides a comprehensive set of features designed to ease system development and minimize system cost. It supports the common space vector modulation (SVM) techniques used for BLDC motor control, as well as linear voltage mode control and pulse width modulation (PWM) control. It also supports angle-measurement for magnetic-encoder based pid-type motor control.

The DEU9SBB also used in power converters such as DC/DC, AC/DC, and DC/AC converters. It offers ten independent digital-to-analog converters (DACs) providing programmable output voltage ranging from 0.6V to 8V. Furthermore, it integrates all the components needed to design a complete four-quadrant chopper such as waveform generator, PWM comparator, power-on reset circuit, and current sense amplifier.

Working Principle of DEU9SBB

The DEU9SBB is based on advanced CMOS process technology with integrated power switches operating up to 500V with current up to 20A. It is protected against intrinsic faults with efficient integrated protection features including short circuit, over voltage, over current, under voltage, and over temperature. The CEU9SBB can be operated in three modes: single-phase full bridge mode, two-phase full bridge mode, and single-phase half bridge mode.

The DEU9SBB is capable of high PWM frequencies and low dead time to ensure optimal motor performance. It features two synchronization options for external PWM and supports a variety of control algorithms. For sensorless applications, it supports auto-commutation with phase advance, current zero angle feeding, back electromotive force (BEMF) detection, and slope control.

The DEU9SBB also supports various protection features. It features integrated undervoltage lockouts, overvoltage protection, and thermal shutdown. It also supports an analog current limiter and is capable of detecting a permanent short in the load circuit.

In summary, the DEU9SBB is a reliable and cost-effective solution for power conversion, motor control, and other industrial motor applications. Its integrated features make it a powerful and versatile solution for a wide range of applications.
