In recent years, the trend of increasing energy efficiency, household appliances energy-saving standards continue to be revised, compared to the traditional focus on power load larger equipment start and under the rated conditions of energy conservation, in recent years require a smaller load of normal operation more energy-saving trend increasingly Rising up. Allegedly, in the global electricity demand, nearly 50% is used to drive the motor, with the popularity of air conditioning in emerging countries, the global power situation year after year grim. In this context, ROHM developed PrestoMOS, very suitable for low-power-efficient air conditioning and other white goods and industrial equipment such as motor drive, can greatly reduce the application of normal power consumption, to meet the social energy needs.
As a leader in home appliances, ROHM's high-speed trr 600V super-junction MOSFET PrestoMOS product group has added "R60xxMNx series", is ideal for low power consumption of white goods and industrial equipment, such as motor drive. PrestoMOS is the industry's fastest trr performance power MOSFET, known for the industry's smallest switching losses. Because the inverter equipped with white appliances, lower power consumption and get highly acclaimed.
General MOSFET with high-speed switching and low current range of the advantages of low conduction loss, the normal operation of the device can effectively reduce power consumption. "R60xxMNx series" using ROHM's unique Lifetime control technology, not only to maintain the industry's fastest trr performance, and Ron and Qg lower, very helpful to the energy-saving circuit. In the protection of performance at the same time, security has also been further improved, usually, in the event of a short circuit, that is, with a circuit malfunction, flow through the design value of the high current, causing abnormal heat, and even damage the possibility of components. It has been very difficult to ensure superior short-circuit withstand capability due to the relationship between performance and short circuit, and the "R60xxMNx series" utilizes the advantages of ROHM's analog technology to the cause of thermal runaway - parasitic bipolar transistors Has been successfully optimized to ensure that the motor drive must be short-circuit tolerance, help to improve the reliability of the application.You can buy the electronic parts from here.
Self-conduction refers to the MOSFET in the off state, the high-side main switch once turned on, the low-side MOSFET drain-source voltage increases sharply, the voltage is the gate sensor, the gate voltage rise, MOSFET malfunction. This phenomenon causes the MOSFET to generate its own power loss. The "R60xxMNx series" by optimizing the parasitic capacitance, the loss can be controlled in a very small minimum range.
The R60xxMNx series, which is the development of the ROHM MOSFET product family, has also successfully made Ron and Qg significantly on the basis of maintaining the special chip structure of ROHM and maintaining the characteristics of PrestoMOS "high-speed trr performance" reduce. Thus, in the case of motor-driven applications such as inverter air conditioner, the power loss at light load is reduced by about 56% compared with the conventional IGBT, and the energy saving effect is remarkable.
Not only that, "R60xxMNx series" using ROHM years of accumulated advantages of analog technology, but also to achieve a super short circuit tolerance, to reduce the circuit malfunction caused by abnormal heat caused by the risk of damage, help to improve the application reliability.
