Typical Applications
IFX9201SGAUMA1 is suitable for 7 applications: Power Tool Motor Drive, Home Appliance Pump and Valve Control, Building Automation Damper Actuator, Medical Infusion Pump Motor Control, Battery Management Relay Driver, Industrial Fieldbus Motor Node, Robotic Actuator Module.
Power Tool Motor Drive
The IFX9201SGAUMA1 is well-suited for brushed-DC motor control in cordless power tools such as drills, screwdrivers, and small saws. Its 5 V to 36 V supply range covers 18 V and 36 V battery packs common in professional cordless tool platforms, and the 6 A continuous current rating handles the high inrush loads seen at motor startup. The integrated SPI diagnostics allow the tool's microcontroller to detect stalled-rotor conditions and trigger safety shutoff within milliseconds, protecting both the user and the motor windings from damage.
Recommended
Home Appliance Pump and Valve Control
In washing machines, dishwashers, and refrigerator water dispensers, the IFX9201SGAUMA1 drives small DC pumps and solenoid valves with precise PWM speed control. The 25 kHz PWM capability supports quiet operation above the audible range, and the exposed-pad DSO-12 package fits within the compact motor-control modules mounted on the appliance chassis. The device's undervoltage lockout protects the appliance electronics during brownout conditions, while overtemperature protection prevents damage if the pump is mechanically stalled.
Recommended
Building Automation Damper Actuator
HVAC damper actuators in commercial building automation systems use the IFX9201SGAUMA1 to drive small DC gear motors that open and close air-flow valves. The 36 V maximum supply accommodates 24 V industrial bus rails common in building-management systems, and the SPI interface allows central BMS controllers to poll actuator position and fault status. The device's low quiescent current and wide operating temperature range support 24/7 operation in ceiling-mounted actuator housings.
Recommended
Medical Infusion Pump Motor Control
Portable medical infusion pumps require precise, low-speed DC motor control with redundant safety monitoring - a use case well served by the IFX9201SGAUMA1's SPI diagnostics and short-circuit detection. The exposed-pad PG-DSO-12-17 package fits within the compact pump housing, and the device's medical-relevant reliability features (overtemperature shutdown, undervoltage lockout) support IEC 60601-1 system compliance when properly designed. The 6 A continuous rating covers most small peristaltic and syringe-pump motor requirements in ambulatory devices.
Recommended
Battery Management Relay Driver
In 12 V and 24 V battery management systems for industrial and telecom backup applications, the IFX9201SGAUMA1 drives latching relays that disconnect battery strings during fault conditions or maintenance cycles. The 5 V minimum supply allows direct operation from deeply discharged battery packs, and the integrated current limit protects the relay coils from overcurrent damage. The SPI diagnostics enable the battery management controller to verify successful relay state changes by monitoring current feedback.
Recommended
Industrial Fieldbus Motor Node
Decentralized motor-drive nodes on industrial fieldbus networks (PROFIBUS, CANopen, EtherCAT) use the IFX9201SGAUMA1 as the final power stage driving small DC motors in conveyor diverters, sorting arms, and packaging machinery. The SPI interface connects directly to a fieldbus communication controller for bidirectional diagnostic reporting, while the 36 V supply range matches common 24 V industrial rail voltages. The exposed-pad package supports the sustained 6 A operation typical in 24/7 production environments.
Recommended
Robotic Actuator Module
Small robotic actuators in collaborative robots (cobots) and educational robotics platforms use the IFX9201SGAUMA1 to drive joint motors with precise torque control via PWM. The device's 25 kHz PWM frequency enables smooth torque ripple reduction, while the SPI fault register supports predictive maintenance algorithms that flag bearing wear before catastrophic failure. The compact PG-DSO-12-17 package allows integration directly onto actuator PCBAs alongside the position encoder and fieldbus interface.

- Higher continuous current in same package footprint (vs BTS3046SDRATMA1)
- Wide 5 V to 36 V supply range covers industrial and battery applications (vs TLE9201SGAUMA1)
Design Notes
Estimated: at 6 A continuous load and 24 V supply driving a 12 V motor, the IFX9201SGAUMA1 dissipates approximately (24 V - 12 V) * 6 A = 72 W. With proper PCB layout using the exposed pad tied to at least 6 square centimeters of 2 oz copper, the junction-to-ambient thermal resistance of the PG-DSO-12-17 package allows continuous 6 A operation. Without adequate copper, thermal shutdown will trigger at lower currents. Always verify junction temperature in worst-case load conditions.
Place supply bypass capacitors (10 uF ceramic + 100 nF high-frequency) within 5 mm of the VS pin, and motor output capacitors close to the OUT1 and OUT2 pins. Use wide copper traces (at least 2 mm or 30 mils) for motor current paths to minimize voltage drop and EMI. Connect the exposed pad to a ground pour using multiple thermal vias (at least 9 vias in a 3x3 grid) for efficient heat transfer to internal PCB copper layers.
The IFX9201SGAUMA1 requires logic supply sequencing - the 3.3 V or 5 V logic rails should be stable before VS rises to avoid undefined SPI register states. Do not exceed 36 V on VS even transiently, as the internal MOSFET avalanche rating may be exceeded. Always read the SPI fault register after motor start to detect stalled-rotor conditions, and use the EN pin for safe motor disable during firmware initialization.
PWM chopping at frequencies above 20 kHz keeps switching harmonics above the audible band, reducing acoustic noise in motor applications. For EMI-sensitive designs, add small gate resistors (10-100 ohm) in series with the OUT pins to slow the switching edge and reduce high-frequency emissions. A 100 nF ceramic capacitor across the motor terminals helps suppress conducted EMI on the motor leads.
