Digital Isolators Digital isolators are an essential component of any electronic system. A digital isolator is a semiconductor device used to provide an electrical isolation barrier between the electrical components of an electronic system. The most popular design for digital isolators is the ADUM240E0BRIZ. Digital Isolators are widely used in applications such as power supplies, automotive systems, industrial equipment, motor control and medical equipment. The ADUM240E0BRIZ provides the highest level of isolation, superior reliability, and excellent performance. By employing specialized isolation technologies, this isolator ensures the highest levels of electrical isolation and noise suppression. The ADUM240E0BRIZ is designed to provide an isolation barrier between two circuits while maintaining very low levels of power and noise dissipation. The isolator has a galvanic isolation layer that separates the two circuits. The galvanic isolation layer provides isolation of up to 2 kV of direct-current (DC) and 50 kHz of alternating-current (AC) power. Additionally, the ADUM240E0BRIZ has very low power consumption, and low attritted power-up/power-down requirements and low leakage current. The device utilizes CMOS technology and isolated bi-directional signal transfer. It is designed to operate from 8 to 32 volts of DC input power and provides an isolation barrier of up to 1· 5 kV of RMS (root-mean-square) dielectric strength at a frequency of 50 kHz. The ADUM240E0BRIZ features high switching energy efficiency, non-inverting monitoring signal and shunt-mode architecture. The shunt-mode architecture enables the device to maintain electrical isolation between two circuits, even when both of them are tied together. This makes the device suitable for a wide range of applications such as motor control, power supplies and medical equipment.The working principle behind the ADUM240E0BRIZ relies on two core components, the interium bridge and the sensing core. The interium bridge provides isolation by utilizing a negative feedback system. When the voltage across the sensing core is less than a predetermined threshold voltage, the interium bridge is closed (allowing current to pass) and when the voltage is higher, the interium bridge is opened (blocking current).The ADUM240E0BRIZ also features an active monitoring/control cell. This active monitoring/control cell is used to detect any faults or abnormalities that may occur and take the appropriate action. The device also features a soft start/stop circuitry which helps to limit the inrush current, thus providing better protection during power-up.In conclusion, the ADUM240E0BRIZ is a reliable and efficient digital isolator suitable for a wide range of applications. It provides a high level of customer satisfaction due to its innovative design, excellent electrical isolation and low power consumption, as well as its shunt-mode architecture and active monitoring/control cell.
