The circuits described in this datasheet are covered under US Patent #5,663,878 and other patents pending.

Description

The UCC3751 controller is designed for driving a power stage that generates low frequency, high voltage sinusoidal signals for telephone ringing applications. The controller and the power stage are most suitable for single line applications where low cost, high efficiency and minimum parts count are critical. In addition to providing the sinusoidal ringing signal, the controller and the power stage are designed to provide the required DC voltage across the output when the phone goes off-hook. The DC voltage is also added as the offset to the ringing signal. This feature eliminates the need to have a separate talk battery voltage power supply as well as relays and drivers to switch between the ringing voltage and the talk battery.
