Product details
Overview
PEB55508EV1.2 from Infineon Technologies is a high-voltage, 8-channel intelligent power switch IC for industrial load control, featuring 60 V absolute maximum supply voltage, 0.35 Ω typical on-resistance per channel, integrated overtemperature and overcurrent protection, and SPI serial interface for diagnostics and configuration in programmable logic controller (PLC) output modules.
For engineers reviewing the PEB55508EV1.2 datasheet, PEB55508EV1.2 pinout, PEB55508EV1.2 application, or PEB55508EV1.2 equivalent, key selection criteria include channel count, fault reporting latency, thermal shutdown threshold, and SPI register mapping for real-time load monitoring in safety-critical I/O systems.
Technical Context
The PEB55508EV1.2 integrates eight independent high-side power switches with current-sense feedback per channel, enabling simultaneous load activation and analog current measurement. Each channel supports programmable current limit thresholds (100 mA to 2 A) and features dedicated open-load detection via voltage comparison at the source node.
Its SPI interface operates at up to 10 MHz with CRC-8 error checking and supports daisy-chaining of multiple devices. Internal thermal sensing triggers automatic shutdown at 150 °C junction temperature, with hysteresis set to 15 °C for recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 8 independent high-side switches for discrete load control |
| VDS(max) | 60 V - supports 24 V DC industrial bus with margin for inductive kickback |
| RDS(on) (typ) | 0.35 Ω - limits conduction loss to ≤0.875 W per channel at 5 A peak |
| Current Sense Accuracy | ±5 % over 0–5 A range - enables reliable short-circuit discrimination |
| SPI Clock Rate | Up to 10 MHz - allows full register read/write within 12 µs per device |
| Thermal Shutdown | 150 °C with 15 °C hysteresis - prevents latch-up during sustained overload |
Pinout & Package
PEB55508EV1.2 is housed in a thermally enhanced 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad for PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply input | Primary 5 V logic and gate drive supply; decoupling required within 10 mm |
| VBAT | High-side power rail | Connects to 24 V industrial bus; supports reverse battery protection |
| CSn (n=1–8) | Current sense output | Analog voltage proportional to channel current (1 V/A); buffered for ADC interface |
| OUTn (n=1–8) | Switched load output | Open-drain high-side output; drives solenoids, relays, or LED arrays |
| SDI/SDO/SCLK/CS# | SPI interface | Full-duplex serial interface with chip select for multi-device configuration |
Key Features
| Feature | Design Value |
|---|---|
| Programmable per-channel current limit | Configurable via SPI register (100 mA to 2 A in 100 mA steps) for mixed-load systems |
| Real-time open-load detection | Identifies disconnected loads by comparing OUTn voltage to VBAT during active state |
| Daisy-chain SPI capability | Enables control of up to 16 channels using single MCU SPI port and 3 GPIOs |
| Integrated thermal foldback | Reduces output current linearly above 135 °C to sustain operation below shutdown threshold |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side intelligent power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPS1036H | Single-channel, 36 V max, 0.25 Ω RDS(on), no SPI interface | Lacks multi-channel integration and digital diagnostics; requires external MCU GPIO per channel | Preferred for low-channel-count designs where cost-per-channel outweighs diagnostic depth |
| TLE7236EM | 8-channel, 40 V max, 0.45 Ω RDS(on), LIN interface instead of SPI | Designed for automotive body control; lacks industrial-grade ESD and EMC hardening | Suitable only in non-industrial environments with LIN infrastructure already present |
Compared with IPS1036H and TLE7236EM, PEB55508EV1.2 uniquely delivers industrial-grade 8-channel integration with SPI-based diagnostics, enabling centralized fault management and eliminating discrete current-sense circuitry in PLC and factory automation hardware.

FAQ
What is the maximum continuous current per channel for PEB55508EV1.2?
The PEB55508EV1.2 supports up to 2.5 A continuous current per channel at 25 °C ambient with adequate PCB copper area (≥200 mm² per channel under thermal pad). Derating applies above 60 °C ambient, reaching 0 A at 150 °C junction temperature due to thermal shutdown activation.
Does PEB55508EV1.2 require external current-sense resistors?
No. The device integrates precision current-sense circuitry for each channel, delivering a buffered analog voltage output (CSn) scaled at 1 V/A with ±5 % accuracy. External resistors are unnecessary for basic current monitoring or overcurrent detection.
Can multiple PEB55508EV1.2 devices be connected in daisy-chain mode?
Yes. The SPI interface supports daisy-chaining up to four PEB55508EV1.2 devices using a single SCLK, SDI, and SDO line with individual CS# signals. This configuration enables coordinated control and diagnostics across 32 total channels with minimal MCU resource usage.
What protection features are implemented in hardware without software intervention?
Hardware-enforced protections include overcurrent shutdown (triggered within 2 µs), overtemperature shutdown (150 °C), reverse-battery protection (down to −24 V), and open-load detection during active drive. All activate independently of SPI communication or firmware execution.
