Product details
Overview
IFX27001TF V18 from Infineon Technologies is a high-side power switch IC designed for 12 V automotive load control. It features overtemperature shutdown, overcurrent protection, and reverse battery protection. Typical applications include body control modules and lighting control in passenger vehicles.
For engineers reviewing the IFX27001TF V18 datasheet, IFX27001TF V18 pinout, IFX27001TF V18 application, or IFX27001TF V18 equivalent, key selection criteria include current rating (4.5 A continuous), on-resistance (90 mΩ max), fault reporting via open-drain status pin, and AEC-Q100 Grade 1 qualification.
Technical Context
The IFX27001TF V18 integrates a vertical DMOS high-side switch with integrated charge pump, enabling operation from 5.5 V to 28 V supply. It uses internal current sensing and thermal foldback to limit power dissipation during overload conditions.
Its diagnostic architecture includes an open-drain INH output that signals overtemperature, overcurrent, or short-circuit faults. The device supports PWM switching up to 10 kHz and features fast turn-on/turn-off times (tON = 10 µs, tOFF = 15 µs).
Key Specifications

| Continuous Output Current | 4.5 A - enables direct driving of medium-power solenoids, relays, and LED arrays |
| RDS(on) Max | 90 mΩ at 25 °C - limits conduction loss to ≤1.8 W at 4.5 A, reducing heatsink requirements |
| Fault Reporting | Open-drain INH pin - provides active-low fault indication compatible with 3.3 V/5 V microcontrollers |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for under-hood automotive use without derating |
| ESD Protection | ±2 kV HBM - meets ISO 10605 requirements for automotive electronics robustness |

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 |
|---|---|---|---|
| INFINEON BTS724G | Higher current rating (7.5 A), larger TO-263-7 package, no reverse battery protection | Better suited for higher-power fans or pumps; lacks reverse polarity hardening | Select when load current exceeds 4.5 A and reverse battery risk is mitigated externally |
| NXP MC33883 | Lower RDS(on) (60 mΩ), integrated current sense analog output, no INH pin | Preferred for closed-loop current regulation; requires external fault processing logic | Choose when analog current monitoring is required and microcontroller has ADC resources |
Compared with BTS724G and MC33883, the IFX27001TF V18 offers balanced performance for mid-power automotive loads with built-in reverse battery protection and simple digital fault signaling-reducing system-level component count without sacrificing robustness.

FAQ
What is the maximum allowable junction temperature for IFX27001TF V18?
The IFX27001TF V18 triggers thermal shutdown at 175 °C junction temperature and resumes operation once the die cools to 155 °C. This hysteresis prevents oscillation during sustained overload. The device is rated for continuous operation up to 125 °C ambient when mounted on a 2-layer PCB with 200 cm² copper area per 1 oz copper layer.
Does IFX27001TF V18 require an external flyback diode for inductive loads?
No. The IFX27001TF V18 integrates an internal freewheeling path that safely clamps inductive kickback during turn-off. This eliminates the need for an external flyback diode in most automotive solenoid and relay applications, reducing bill-of-materials cost and board space.
Can IFX27001TF V18 be used in 24 V commercial vehicle applications?
Yes. Its 5.5 V to 28 V supply range supports 24 V nominal systems, including heavy-duty trucks and buses. However, continuous current must be derated to 3.2 A at 24 V due to increased power dissipation; thermal design must account for higher VBB2/RDS(on) losses.
How is the INH pin configured during normal operation?
During normal operation with no fault, the INH pin remains in high-impedance (open-drain) state and must be pulled up externally (typically 3.3 V or 5 V). It pulls low only during overtemperature, overcurrent, or short-circuit events, providing unambiguous fault signaling to the host controller.
