Product details

Overview

PEB 2026 T-S V1.1 from Infineon Technologies is an ISDN High Voltage Power Controller (IHPC) designed to supply and protect a single two-wire ISDN transmission line. It supports battery voltage up to 130 V, provides programmable current limiting via external resistor R_REF, features overtemperature-triggered current reduction, and integrates Smart Power Technology (SPT 170) for reliable 170 V operation in telecom line feeding applications.

For engineers reviewing the PEB 2026 T-S V1.1 datasheet, PEB 2026 T-S V1.1 pinout, PEB 2026 T-S V1.1 application, or PEB 2026 T-S V1.1 equivalent, this device serves as a dedicated high-voltage line feed controller with thermal protection, longitudinal disturbance immunity, and logic-controlled enable/disable functionality for ISDN BRI interfaces.

Technical Context

The PEB 2026 implements a CMOS-based high-voltage power controller with integrated bipolar/DMOS SPT 170 process technology, enabling safe operation at up to 130 V battery supply. Its functional core includes a programmable current-limit circuit, temperature-sensing circuitry that reduces line current above threshold, and dual low-pass filtering paths-one for status output (APFI) delay and one for longitudinal AC rejection.

It operates in two primary modes: normal line feeding and current-limited thermal protection mode. The APFI output signals active current limiting with a user-defined delay set by external capacitor C_HP, while a second capacitor suppresses false triggering from longitudinal interference-critical for ISDN line stability under real-world telephony conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Battery voltage range	Up to 130 V DC - supports full ISDN line feed voltage headroom including transients
Current limit programming	Set by external R_REF - enables precise line current tuning from ~20 mA to >100 mA
Thermal foldback threshold	Activates automatically above chip temperature - prevents latch-up or destruction during sustained overload
APFI status delay	Configurable via external C_HP - provides adjustable response time for fault reporting and system coordination
Longitudinal AC rejection	Enabled by second external capacitor - blocks false current limiting from induced AC on twisted-pair lines
Process technology	SPT 170 Smart Power - integrates high-voltage DMOS with CMOS logic for robust 170 V breakdown margin

Pinout & Package

PEB 2026 T-S V1.1 is available in two surface-mount SO-20 variants: P-DSO-20-6 and P-DSO-20-10, differing in leadframe configuration and thermal resistance. Both packages support industrial temperature operation and are optimized for PCB space-constrained ISDN line card designs.

Pin/Terminal	Circuit Role	Design Meaning
V_BAT	Battery supply input	High-voltage DC input (up to 130 V); connects to ISDN line feed rail
V_CC	Logic supply input	5 V CMOS-compatible supply for internal control logic
PFEN / PFENQ	Power enable inputs	Dual complementary logic inputs controlling line feed activation/deactivation
APFI	Active current-limit indicator	Open-drain output with low-pass filtered assertion; signals when ILimit is engaged
R_REF	Current limit reference	Connects external resistor defining nominal line current limit value
C_HP	High-pass filter capacitor terminal	Defines corner frequency and delay of APFI status signal low-pass filter
C_LP	Longitudinal protection capacitor	Filters induced AC to prevent false current limiting on twisted-pair lines
GND	Ground reference	Common return for logic, power, and sensing circuits

Key Features

Feature	Design Value
Programmable line current limit	Adjustable from 20 mA to >100 mA using single external resistor R_REF
Overtemperature current foldback	Automatic reduction of line current above safe junction temperature - avoids thermal runaway
Dual-capacitor filtering architecture	Separate C_HP (status delay) and C_LP (longitudinal immunity) - ensures accurate fault signaling and noise resilience

Equivalent & Alternatives

The following parts are listed as comparable options for similar ISDN high-voltage line feed controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PEF 2026	Same functional block diagram and pinout but rated for extended temperature range (−40°C to +105°C vs. −25°C to +85°C)	Required for outdoor or uncooled central office deployments where ambient exceeds 85°C	Select PEF 2026 when operating beyond industrial temperature limits; otherwise PEB 2026 suffices for standard line cards
PEB 2027	Includes integrated line driver amplifier and differential receiver for full ISDN U-interface transceiver function	Replaces separate SLIC + controller combinations; adds signal path capability	Choose PEB 2027 only if both line feeding and physical layer signal conditioning are needed in same package

Compared with PEF 2026 and PEB 2027, the PEB 2026 T-S V1.1 offers optimal cost and thermal performance for dedicated line feed-only applications within standard industrial temperature ranges, avoiding unnecessary integration overhead or extended qualification costs.

FAQ

What is the maximum allowable battery voltage for PEB 2026 T-S V1.1?

The absolute maximum battery voltage is 130 V DC, as specified in Table 7-1 of the 09.99 datasheet. This rating reflects the device's SPT 170 process capability and includes margin for transient surges common in ISDN line environments. Operation above this voltage risks permanent damage to the internal high-side switch.

How does the PEB 2026 implement thermal protection?

Thermal protection activates when junction temperature exceeds threshold, causing automatic reduction of line current limit-distinct from shutdown. This foldback behavior maintains partial functionality while preventing thermal runaway. The effect is observable in Figure 7-2 (Maximal Line Currents) and documented in Section 3.3 of the datasheet.

Can PEB 2026 T-S V1.1 be used without external capacitors?

No. Two external capacitors are mandatory: C_HP sets APFI status delay and C_LP suppresses longitudinal AC-induced false limiting. Omitting either compromises fault signaling accuracy or causes spurious current limiting during line noise events, violating ISDN reliability requirements per I.430 Annex A.

What is the purpose of the PFEN and PFENQ inputs?

PFEN and PFENQ are complementary logic inputs that together control line feed enable/disable. Both must be asserted (PFEN = high, PFENQ = low) to activate feeding. This dual-signal interface prevents accidental activation due to floating or noisy control lines and supports direct connection to microcontroller GPIOs without additional logic.
