Technical Specifications:

The PEF22554HTV13 is a single-channel SLIC that provides all the necessary functions to interface with an analog telephone line. It features low power consumption, making it suitable for energy-efficient systems. The integrated DC-DC converter generates the required voltages for the SLIC from a single supply voltage. The SLIC provides programmable loop feed characteristics, allowing it to be adapted to different loop conditions. The PEF22554HTV13 generates ringing signals to alert the telephone user of an incoming call. It also provides battery feed to power the telephone set and performs line supervision to detect on-hook and off-hook conditions.

The SLIC includes short circuit protection to prevent damage to the device in the event of a line fault. Overvoltage protection is also included to protect the SLIC from voltage spikes on the telephone line. The PEF22554HTV13 is commonly used in VoIP gateways and ATAs to connect analog telephones to a digital communication network. It is also used in PBXs and CO line cards to provide analog telephone line interfaces.

The integrated functions and protection features of the PEF22554HTV13 simplify system design and improve system reliability. The SLIC's flexible programmability allows it to be used in a variety of applications and environments. Infineon's VINETIC® SLIC family is a well-established and reliable solution for analog telephone line interfaces.
