Infineon Technologies BTM7750GXUMA1

Overview

BTM7750GXUMA1 from Infineon Technologies is a quad-channel automotive power switch IC integrating two high-side and two low-side SMART SIPMOS® D-MOS drivers in a single PG-DSO-28-22 package. It delivers 12 A peak current, 70 mΩ typical high-side R_DS(on) at 25°C, and 45 mΩ typical low-side R_DS(on), with integrated short-circuit, overtemperature, and undervoltage protection - used in DC motor control for automotive seat/mirror actuators.

For engineers reviewing the BTM7750GXUMA1 datasheet, BTM7750GXUMA1 pinout, BTM7750GXUMA1 application, or BTM7750GXUMA1 equivalent, key selection criteria include configurable H-bridge/quad-switch topology, open-drain status flag diagnostics, thermal shutdown hysteresis, and AEC-Q100 qualification for under-hood environments.

Technical Context

The device implements three vertically stacked dies (dual high-side + dual low-side) on separate lead frames, enabling independent source routing for flexible bridge or discrete switching configurations. Each channel uses SMART SIPMOS® technology-integrating CMOS gate drivers, protection logic, and vertical DMOS power stages on one die.

Protection architecture includes analog current-limiting via V_DS-based op-amp monitoring per output, hysteresis-enabled overtemperature shutdown that forces ST low for high-side faults, and TTL/CMOS-compatible Schmitt-trigger inputs with ESD clamping. The open-drain ST pin reports short-circuit-to-VS, short-circuit-to-GND, overload, and thermal fault conditions.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The BTM7750GXUMA1 has an absolute maximum junction temperature of +150°C. Continuous operation is rated up to +125°C ambient with proper PCB copper area (≥200 mm² thermal pad exposure) and airflow. Thermal shutdown activates at ~165°C with 15 K hysteresis, ensuring safe recovery before re-enabling outputs.

Can BTM7750GXUMA1 drive inductive loads without external flyback diodes?

Yes - internal clamp diodes protect high-side outputs against negative voltage spikes during inductive turn-off. However, low-side outputs rely on external freewheeling paths or body diodes of external FETs; for full H-bridge operation, external diodes are recommended across motor terminals to handle bidirectional energy recirculation.

How does the status flag (ST) differentiate between fault types?

The ST pin does not encode fault type - it asserts low for all detected faults (short-circuit-to-GND, short-circuit-to-VS, overload, overtemperature, or UVLO). Fault discrimination requires correlating ST assertion timing with input states (IH1/IH2) and monitoring IL1/IL2 analog currents using an external ADC or comparator.

Is BTM7750GXUMA1 compatible with 24 V commercial vehicle systems?

Yes - its 40 V absolute maximum supply rating and AEC-Q100 Grade 1 qualification cover 24 V nominal systems, including cold-crank (down to 6 V) and load-dump (up to 35 V) transients. Derating curves in the datasheet confirm 12 A peak current remains valid up to 150°C junction temperature in 24 V configurations.
