The IC has a very wide 8V-450V DC operation and can operate with 2V, 24V, and 48V DC power systems and 85V to 265V offline AC systems. According to Ahmed Masood, vice president of marketing at Supertex, the HV7800's wide input voltage range can be used to monitor current, power management applications and LCD TV applications that use LEDs as backlights. The HV7800 is recommended for use in conjunction with the recently introduced HV9911. This IC solves many current sensing design problems - high voltage, high accuracy, fast response time and space considerations. The HV7800 is available in a SOT23-5 package. In line with "green" and RoHS requirements, samples are available now, with shipments of 4 to 6 weeks, and the number of HV7800K1-G is $0.56 when the number reaches 1000. About Supertex Supertex is a mixed-signal semiconductor manufacturer focused on high-voltage products for telecommunications, networking systems, flat panel displays, the medical and electronics industries.
