Wide Input Voltage Range High Side
The HV7800, a new high side, current sensing IC has been introduced by  Supertex.
The device has the operating range of 8V-450V DC. The IC operates by sensing the voltage across an external resistor and transmitting this reading to the ground-referenced circuit at a gain of one with a typical accuracy of +/-1%. It also provides a much easier sensing implementation.
“The wide input voltage range of the HV7800 allows it to be used to monitor current in telecom and base station applications, power management applications, and LCD TVs with LED backlight applications in which the HV7800 is recommended for use in conjunction with our recently introduced LED driver IC, the HV9911,” states Ahmed Masood, from Marketing for Supertex. “The IC solves many current sense design problems–high voltage, high precision, fast response time and space considerations.”
