Product details
Overview
IFX27001TF V26 from Infineon Technologies is a high-side power switch IC designed for 12 V automotive load control, featuring 60 mΩ on-resistance, ±1.5 A continuous current rating, integrated overtemperature and overcurrent protection, and compliant with AEC-Q100 Grade 1. It drives solenoids, relays, and lamps in body electronics modules.
For engineers reviewing the IFX27001TF V26 datasheet, IFX27001TF V26 pinout, IFX27001TF V26 application, or IFX27001TF V26 equivalent, key selection criteria include thermal shutdown behavior, diagnostic flag response time, supply voltage range, enable logic polarity, and short-circuit robustness under pulsed load conditions.
Technical Context
The IFX27001TF V26 integrates a vertical DMOS high-side switch with embedded current-sense amplifier, analog overtemperature detection circuitry, and open-drain fault flag output. It operates from 5.5 V to 28 V supply and supports PWM switching up to 100 Hz.
Its internal charge pump enables full enhancement of the MOSFET across the entire input voltage range, and the diagnostic flag asserts low within 2 µs of overcurrent or overtemperature event detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 60 mΩ max at VIN = 13.5 V, Tj = 25 °C - ensures <1 W conduction loss at 4 A peak |
| IOUT cont. | ±1.5 A - supports sustained operation driving 12 V/18 W incandescent lamps |
| VIN range | 5.5 V to 28 V - compatible with automotive battery transients (ISO 7637-2 Pulse 5a) |
| Fault flag delay | ≤2 µs - enables fast system-level fault isolation in ECU safety monitoring |
| Thermal shutdown | 175 °C junction - protects against sustained overload without external thermal sensor |
| Enable logic | Active-high - simplifies interface with standard microcontroller GPIO without level shifters |
Pinout & Package
IFX27001TF V26 is housed in a PG-TO263-7-1 (D²PAK) thermally enhanced package with exposed drain pad for PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Connects to 12 V battery rail; withstands 40 V transients per ISO 7637-2 |
| GND | Ground reference | Common return path for load current and internal logic; tied to exposed drain pad |
| OUT | Switched output | Drives high-side load; electrically isolated from GND when off |
| IN | Enable input | CMOS-compatible active-high control signal; 3.3 V/5 V tolerant |
| FLAG | Fault indicator | Open-drain output asserting low during overcurrent, overtemperature, or undervoltage lockout |
| IS | Current sense output | Analog voltage proportional to load current (1 V/A); used for closed-loop monitoring |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sense | Provides real-time 1 V/A analog feedback without external shunt resistor or op-amp |
| Fast fault flag response | 2 µs detection-to-flag assertion enables deterministic fault handling in ASIL-B systems |
| Robust short-circuit protection | Withstands >100 ms at 10× rated current before thermal shutdown activates |
| Wide supply range | Operates down to 5.5 V, supporting cold-crank conditions in 12 V vehicles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS724G | Higher RDS(on) (90 mΩ), no integrated current sense output | Lacks analog IS feedback; requires external sensing for closed-loop control | Choose when cost sensitivity outweighs diagnostic capability needs |
| TPS27081A | Lower current rating (0.8 A), no AEC-Q100 qualification, 5 V only supply | Not suitable for automotive 12 V battery environments or ASIL-relevant systems | Consider only for non-automotive industrial 5 V applications |
Compared with BTS724G and TPS27081A, IFX27001TF V26 uniquely combines AEC-Q100 Grade 1 compliance, integrated current sense, and 1.5 A capability in a single D²PAK package-making it optimal for automotive body electronics requiring functional safety-aware diagnostics.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The IFX27001TF V26 has a maximum junction temperature of 175 °C, with thermal shutdown activation at that threshold. Continuous operation is rated up to 150 °C ambient with appropriate PCB copper area (≥100 mm² thermal pad) and airflow. Derating curves in the datasheet define safe operating area versus ambient temperature and load current.
Does the IS pin provide bidirectional current measurement?
No-the IS pin delivers a unidirectional analog voltage proportional to forward load current only (1 V/A), referenced to GND. It does not support reverse current detection or negative current reporting. The device is configured exclusively for high-side switching, so current flows only from VIN to OUT during normal operation.
Can the FLAG pin drive an LED directly without a current-limiting resistor?
No-the FLAG pin is an open-drain output with 20 mA absolute maximum sink current. Driving an LED directly risks exceeding this limit and damaging the output stage. A series current-limiting resistor (e.g., 1 kΩ for 5 V pull-up) is required to keep sink current within specification and ensure reliable flag assertion under all fault conditions.
Is the IFX27001TF V26 qualified for use in ASIL-B systems?
While the IFX27001TF V26 itself is not ASIL-certified, its AEC-Q100 Grade 1 qualification, diagnostic features (FLAG, IS), and failure mode coverage support integration into ASIL-B system architectures when combined with appropriate system-level safety mechanisms such as watchdog timers, redundant monitoring, and fault-handling software per ISO 26262 Part 5.
