PEB 2026 T-S V1.1

Overview

The Infineon PEB 2026 T-S V1.1 is an ISDN High Voltage Power Controller (IHPC) designed to power two-wire ISDN transmission lines. It utilizes Smart Power Technology (SPT 170) and supports battery voltages up to 130 V. The device integrates current limiting, which is programmable via an external resistor, and thermal protection that reduces feeding current during overtemperature conditions to limit junction temperature to approximately 165 °C. Logic inputs PFEN and PFENQ control power switching, while the APFI output signals active current limiting. The component is available in P-DSO-20 packages.

Feature Summary

• Integrated power controller for one ISDN transmission line with battery voltage support up to 130 V
• Programmable current limiting via external resistor RREF
• Thermal protection automatically reduces feeding current to prevent damage from overloads
• Logic-controlled power switching using PFEN and PFENQ inputs

Applications

• Feeding two-wire ISDN transmission lines
• ISDN subscriber loop interface circuits
• Telecom power management systems requiring high-voltage line powering

Procurement Notes

Verify component authenticity through authorized Infineon channels or certified distributors. Confirm package variant (P-DSO-20-6 or P-DSO-20-10) matches design requirements. Check RoHS compliance status as indicated in official documentation. Ensure storage and handling procedures adhere to ESD sensitivity guidelines for CMOS devices.

Selection Notes

Select the P-DSO-20-6 package for applications where the PCB provides sufficient copper area (at least 900 mm²) for heat dissipation. Choose the P-DSO-20-10 package if higher thermal capacitance is needed for fault conditions without additional heatsinks. Calculate external components RREF, CHP, and CTP based on desired current limits and filter characteristics defined in the datasheet.
