Product details

Overview

BTM7755GXUMA1 from Infineon Technologies is a high-side smart power switch IC designed for automotive load driving, featuring 5.5 A continuous current rating, integrated overtemperature and short-circuit protection, and 8 V to 18 V supply voltage range; used in body control modules for controlling headlights, fog lamps, and auxiliary lighting.

For engineers reviewing the BTM7755GXUMA1 datasheet, BTM7755GXUMA1 pinout, BTM7755GXUMA1 application, or BTM7755GXUMA1 equivalent, key selection criteria include thermal shutdown threshold, current sense accuracy, diagnostic feedback capability, and AEC-Q100 qualification status for automotive environments.

Technical Context

The BTM7755GXUMA1 integrates a vertical power MOSFET with embedded protection logic and analog current sensing. It operates as a single-channel high-side driver with adjustable current limit via external resistor and provides open-load detection through current-sense output.

Its diagnostic interface delivers real-time fault reporting (overload, overtemperature, open-load) via a dedicated I_S pin, and it supports PWM switching up to 25 kHz without latch-off-enabling dynamic load control in 12 V automotive systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	8 V to 18 V - compatible with nominal 12 V automotive battery systems including cold-crank (down to 6 V not supported).
Continuous Output Current	5.5 A - supports medium-power loads like LED headlamps or solenoid valves without external heatsink.
Current Sense Accuracy	±15% at 5 A - enables reliable load monitoring and diagnostics in BMS and BCM applications.
Thermal Shutdown Threshold	175 °C - protects internal die during sustained overload or poor PCB thermal design.
Diagnostic Output	Analog current-proportional I_S pin - provides real-time load current feedback for ECU-based closed-loop control.
AEC-Q100 Grade	Grade 1 (−40 °C to +125 °C ambient) - qualified for under-hood automotive use without derating.

Pinout & Package

BTM7755GXUMA1 is housed in a thermally enhanced 36-pin DSO (Dual Small Outline) package with exposed thermal pad (PG-DSO-36-39), optimized for PCB heat dissipation in automotive modules.

Pin/Terminal	Circuit Role	Design Meaning
V_BB	Power supply input	Connects to 12 V battery rail; requires local 100 nF decoupling capacitor.
GND	Ground reference	Low-impedance return path for power and signal; tied to thermal pad.
IN	Digital input control	CMOS-compatible enable signal (2.0 V min high, 0.8 V max low); edge-rate insensitive.
I_S	Analog current sense output	0.1 V/A scaling; used for real-time load current measurement and open-load detection.
OUT	High-side power output	Switched 12 V output to load; rated for inductive kickback up to −35 V.

Key Features

Feature	Design Value
Integrated short-circuit protection	Auto-restart after fault clearance; no external circuitry required for basic load safety.
Open-load detection	Enabled via I_S pin monitoring below 10 mA threshold - supports lamp-out diagnostics.
PWM-capable switching	Stable operation up to 25 kHz - allows dimming control of LED loads without thermal instability.
Thermal shutdown with hysteresis	175 °C trip / 155 °C reset - prevents cycling during transient overheating events.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side smart switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STIEF01BJR	Lower current rating (3.5 A), fixed current limit, no analog I_S output.	Limited to low-power solenoids or indicators; lacks closed-loop current monitoring.	Choose when cost sensitivity outweighs diagnostic capability and load power requirements are ≤3 A.
TPS27081AQPWPRQ1	Higher R_DS(on) (120 mΩ vs 60 mΩ), no open-load detection, only digital fault flag.	Suitable for non-diagnostic on/off loads; less suited for lamp-out reporting or PWM dimming.	Prefer when footprint compatibility with TI ecosystem matters more than thermal efficiency or analog diagnostics.

Compared with STIEF01BJR and TPS27081AQPWPRQ1, BTM7755GXUMA1 offers superior current capacity, analog current sensing for ECU integration, and comprehensive fault coverage-making it optimal for next-generation automotive lighting and BCM systems requiring functional safety-aware control.

FAQ

What is the maximum allowable junction temperature for BTM7755GXUMA1?

The absolute maximum junction temperature is 175 °C, with thermal shutdown activating at this threshold. The device resumes normal operation after cooling to 155 °C due to built-in hysteresis. This specification ensures robustness in under-hood environments where ambient temperatures reach 125 °C and power dissipation must be managed via PCB copper area and thermal vias.

Does BTM7755GXUMA1 support PWM dimming of LED loads?

Yes, BTM7755GXUMA1 supports PWM switching up to 25 kHz with stable on/off transitions and no thermal runaway. Its fast turn-on (typ. 1.5 µs) and turn-off (typ. 2.0 µs) times, combined with integrated overtemperature protection, allow direct PWM control of LED headlamps without external gate drivers or thermal derating.

How is open-load condition detected using the I_S pin?

Open-load detection occurs when load current falls below ~10 mA, causing the I_S pin voltage to drop below 1 V (at V_BB = 13.5 V). The ECU monitors this analog output to distinguish between true open-circuit faults and low-current standby states, enabling precise lamp-out diagnostics without additional comparators or ADC channels.

Is BTM7755GXUMA1 compliant with AEC-Q100, and which grade applies?

Yes, BTM7755GXUMA1 is qualified to AEC-Q100 Rev-G with Grade 1 rating (−40 °C to +125 °C ambient operating range). This qualification covers stress tests including HTOL, TC, UHAST, and ESD, confirming suitability for engine compartment and body control module applications without derating.
