General Description
The Supertex HV440 is a monolithic integrated circuit capable of generating up to 70V RMS sine wave output at frequencies of 15 to 60Hz with a load of 5 North American RENs. Its out putrating can be enhanced to 20 North American RENs with the addition of two Supertex MOSFETs: one N-Channel MOSFET, the TN2524N8, and one P-Channel MOSFET, the TP2522N8.

Features
► 220V maximum operating voltage
► Integrated high voltage transistors
► Up to 70VRMS ring signal
► Pulse by pulse output over current protection
► 5 REN output capability
► External MOSFETs enhance output rating to 20 REN

Applications
► Microcontroller or microprocessor controlled high voltage ring generator
► Set-top/street box ring generator
► Pair gain ring generator
► Wireless local loops
► Fibre in the loop/to the curb
► Coax cable loop
