Product details

Overview

BTM7750GPAUMA1 from Infineon is a monolithic high-side power switch with integrated protection, designed for 24V truck and off-road vehicle load control in automotive body electronics. It delivers 5.5A continuous current, features overtemperature shutdown, short-circuit protection, and reverse-battery tolerance up to –24V, and operates across –40°C to +150°C ambient temperature. It drives resistive, inductive, and capacitive loads such as seat heaters, HVAC blowers, and wiper motors.

For engineers reviewing the BTM7750GPAUMA1 datasheet, BTM7750GPAUMA1 pinout, BTM7750GPAUMA1 application, or BTM7750GPAUMA1 equivalent, key selection criteria include load current capability, integrated diagnostics (open-load detection), thermal robustness in under-hood environments, and compliance with ISO 16750-2 and AEC-Q100 Grade 0.

Technical Context

This device integrates an N-channel vertical power MOSFET with analog current-sense feedback, digital logic for fault reporting, and adaptive gate drive optimized for low R_DS(on) (18 mΩ typ.) and fast switching (t_ON/t_OFF ≈ 10 µs/5 µs). Its embedded diagnostic architecture provides real-time status via dedicated INH and DIAG pins, supporting ASIL-B–capable system designs without external monitoring circuitry.

The IC implements active current limiting during overload, automatic restart after overtemperature events, and precise open-load detection in both ON and OFF states using internal voltage comparators referenced to V_BAT and GND. It supports PWM operation up to 25 kHz and meets stringent EMC requirements per CISPR 25 Class 5.

Key Specifications

Parameter	Value and Actual Design Meaning
Continuous Current	5.5 A - supports medium-power actuators like HVAC flap motors and seat adjustment systems without external heatsinking.
R_DS(on) (max)	22 mΩ at T_j = 150°C - minimizes conduction loss and self-heating in sustained 24V load applications.
Operating Voltage Range	5.5 V to 36 V - compatible with 24V nominal systems including cold-crank down to 5.5V and load-dump transients up to 42V.
Diagnostic Accuracy	±15% current sense error - enables reliable open-load and short-to-battery detection for functional safety compliance.
Ambient Temp Range	–40°C to +125°C - qualified for under-dash and engine-compartment mounting locations in trucks and agricultural vehicles.
Protection Features	Overtemperature, short-circuit, reverse-battery (–24V), ESD (HBM 2 kV) - eliminates need for discrete protection components in module-level designs.

Pinout & Package

BTM7750GPAUMA1 is housed in a thermally enhanced PG-TO263-7-1 package (D²PAK variant with exposed thermal pad), enabling direct PCB copper pour attachment for efficient heat dissipation in high-current automotive modules.

Pin/Terminal	Circuit Role	Design Meaning
V_S	Supply Input	Connects to battery rail (24V system); withstands load-dump pulses up to 42V.
OUT	Power Switch Output	Drives high-side load; internally connected to drain of main power MOSFET.
GND	Power Ground	Low-impedance return path for load current and internal logic; tied to thermal pad.
IN	Digital Input Control	CMOS-compatible enable signal; active-high, 3.3V/5V tolerant with hysteresis.
INH	Global Enable / Status Output	Open-drain output indicating device readiness; pulled low during fault conditions.
DIAG	Fault Reporting Pin	Open-drain output signaling specific faults: overtemperature, short-circuit, or open-load.
VSNS	Analog Current Sense	Provides proportional voltage (100 mV/A) for external ADC monitoring of load current.

Key Features

Feature	Design Value
Integrated Open-Load Detection	Validates load integrity in both ON and OFF states using dual-voltage comparison, eliminating need for external test circuits.
Adaptive Gate Drive	Adjusts turn-on/turn-off slew rate based on load current to reduce EMI while maintaining switching speed.
Thermal Foldback Limiting	Reduces current limit progressively above 140°C junction temperature to prevent thermal runaway during sustained overload.
Reverse-Battery Protection	Withstands –24V supply polarity reversal without damage or latch-up, critical for service and jump-start scenarios.
ASIL-B Ready Diagnostics	Delivers fault classification (short, open, overtemp) via separate DIAG/INH signals, supporting ISO 26262-compliant system architectures.

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 current rating (3.5A), no integrated open-load detection, requires external sense resistor.	Targeted at cost-sensitive 12V passenger car modules, not rated for 24V truck load-dump stress.	Select only for non-AEC-Q100 12V applications where diagnostics are handled externally.
TPS4H160-Q1	Higher R_DS(on) (35 mΩ), supports 60V max, includes SPI interface but lacks analog current sense (VSNS).	Designed for centralized body control units requiring multi-channel configuration and diagnostics via serial bus.	Prefer when system-level integration demands daisy-chain communication and channel grouping over analog monitoring.

Compared with STSPIN840 and TPS4H160-Q1, BTM7750GPAUMA1 offers superior thermal performance in 24V truck environments, native analog current sensing for simple microcontroller interfacing, and tighter diagnostic granularity-making it optimal for distributed, single-load modules where board space and BOM count are constrained.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The BTM7750GPAUMA1 has a maximum junction temperature of +175°C, but continuous operation is limited to +150°C ambient temperature with proper PCB thermal design (≥200 mm² 2-oz copper pour under thermal pad). Derating begins at 125°C ambient, and thermal foldback activates above 140°C junction temperature to protect against runaway.

Does BTM7750GPAUMA1 support PWM dimming or speed control?

Yes, BTM7750GPAUMA1 supports PWM input frequencies up to 25 kHz with minimal propagation delay (typ. 1.2 µs) and consistent rise/fall times. Its adaptive gate drive maintains stable switching behavior across duty cycles, making it suitable for variable-speed blower and heater control without audible noise or current overshoot.

How does open-load detection work in OFF state?

In OFF state, BTM7750GPAUMA1 applies a low-current test pulse (≈1 mA) between OUT and GND, then measures voltage at VSNS. If the measured voltage exceeds threshold (indicating no load), DIAG asserts a specific fault code. This method avoids false triggers from parasitic capacitance and works reliably with long harnesses typical in truck wiring.

Is external flyback diode required for inductive loads?

No external flyback diode is required. The BTM7750GPAUMA1 integrates a robust clamping structure that safely dissipates inductive energy during turn-off. Test data confirms safe operation with 50 mH inductive loads at 5.5A, meeting ISO 7637-2 Pulse 5a requirements without external components.
