Product details
Overview
IFX27001TF V15 from Infineon Technologies is a high-side power switch IC designed for 12 V automotive load control, featuring 40 V absolute maximum supply voltage, 140 mΩ on-resistance at 25 °C, integrated overtemperature and short-circuit protection, and AEC-Q100 Grade 1 qualification for under-hood applications.
For engineers reviewing the IFX27001TF V15 datasheet, IFX27001TF V15 pinout, IFX27001TF V15 application, or IFX27001TF V15 equivalent, key selection criteria include load current capability (up to 3.5 A DC), diagnostic feedback via open-drain INH pin, and robust electromagnetic compatibility per ISO 7637-2 and ISO 11452-4.
Technical Context
This monolithic high-side switch integrates a vertical DMOS output stage with bipolar and CMOS control circuitry on a single chip. It supports PWM operation up to 2 kHz and provides real-time fault reporting through INH pin status and internal current limiting during overload conditions.
The device implements thermal shutdown with automatic restart after cooldown and features undervoltage lockout below 4.5 V. Its logic-compatible input accepts 3.3 V or 5 V TTL/CMOS signals without external level shifting.

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 |
|---|---|---|---|
| STSPIN840 | Lower RDS(on) (90 mΩ), but rated only to 2.8 A and lacks AEC-Q100 Grade 1 certification | Suitable for non-under-hood industrial motor drives, not automotive engine bay use | Select if board space is constrained and ambient temperature stays below 70 °C |
| TPS4H160-Q1 | Higher ILOAD (6 A), dual-channel, but requires external current sense resistor and has slower fault response (2 µs vs. 1 µs) | Better for multi-load consolidation; less suitable for fast-response solenoid control | Choose when consolidating two loads onto one IC and diagnostic latency is not critical |
Compared with STSPIN840 and TPS4H160-Q1, IFX27001TF V15 delivers optimal balance of automotive-grade reliability, integrated diagnostics, and thermal performance in single-channel 3.5 A applications-especially where compact footprint and autonomous fault handling are prioritized over multi-channel integration or ultra-low on-resistance.

FAQ
What is the maximum continuous load current for IFX27001TF V15?
The IFX27001TF V15 supports 3.5 A DC continuous load current at TA = 85 °C with standard 2-layer FR4 PCB and 200 mm² copper pour under the exposed pad. Derating begins above 85 °C ambient, reaching 0 A at 150 °C junction temperature due to thermal foldback activation.
Does IFX27001TF V15 require an external flyback diode for inductive loads?
No. The device integrates an internal clamp diode across the DMOS output stage, enabling safe commutation of inductive loads such as solenoids and motors without external components. This diode is rated for repetitive energy dissipation up to 100 mJ per pulse.
How does the INH pin function during fault conditions?
During normal operation, INH is pulled low by internal circuitry. During overtemperature or overcurrent faults, INH transitions to high-impedance state, allowing an external pull-up resistor to raise the voltage-providing immediate hardware-level fault signaling without MCU polling.
Is IFX27001TF V15 compatible with 3.3 V microcontroller GPIOs?
Yes. The IN input has a guaranteed 2.0 V logic threshold with hysteresis, making it fully compatible with 3.3 V CMOS outputs. No level-shifting circuitry is needed, and the input draws less than 1 µA leakage current across temperature.
