Product details
Overview
IFX9201SGAUMA1 from Infineon Technologies is a 6 A automotive-grade H-bridge motor driver IC with integrated SPI diagnostics, PWM/DIR control interface, 100 mΩ RDS(on) per switch (Tj = 25 °C), short-circuit and overtemperature latch protection, and open-load detection in both ON/OFF states - used for bidirectional DC motor control in body electronics and HVAC actuators.
For engineers reviewing the IFX9201SGAUMA1 datasheet, IFX9201SGAUMA1 pinout, IFX9201SGAUMA1 application, or IFX9201SGAUMA1 equivalent, key selection considerations include chopper current limitation at 8 A typ., VS undervoltage shutdown, SO logic-level programmability via VSO (3.3 V/5 V), and PG-DSO-12-17 thermal performance with exposed GND heat slug.
Technical Context
The IFX9201SGAUMA1 implements a fully integrated n-channel H-bridge with charge-pump-based high-side gate drive - eliminating need for external bootstrap capacitors. Its control logic accepts PWM/DIR inputs and supports tristate disable via DIS, enabling freewheeling and braking modes per truth table.
SPI interface (SI/SO/SCK/CSN) delivers real-time fault reporting including short-circuit-to-GND/supply, overtemperature, open-load, and undervoltage conditions. Diagnostics can be read as detailed register data or condensed into a single error flag output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 6 A continuous (Tc = 100 °C); enables driving medium-power DC motors without external heatsinking. |
| RDS(on) per Switch | 100 mΩ typ. @ Tj = 25 °C; limits conduction loss to ≤360 mW per channel at 6 A. |
| Current Limit Threshold | 8 A typ.; triggers chopper mode to maintain safe average current under overload or stall. |
| PWM Frequency Support | Up to 20 kHz; avoids audible noise in motor applications while preserving microcontroller timer resources. |
| Logic Compatibility | TTL/CMOS 3.3 V or 5 V on DIR/PWM/DIS/CSN/SCK/SI; SO level set by VSO pin voltage choice. |
| Protection Features | Latched shutdown on short-circuit (GND/supply/load), overtemperature (>175 °C), and VS undervoltage (<4.5 V). |
| Open-Load Detection | Active during PWM operation and static OFF state; distinguishes open circuit from high-impedance load disconnect. |
Pinout & Package
IFX9201SGAUMA1 uses the PG-DSO-12-17 package: thermally enhanced 12-pin DSO with exposed GND heat slug (bottom side), RoHS-compliant, creepage/clearance optimized for automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DIR | Direction control input | Defines motor rotation direction (forward/reverse); TTL/CMOS compatible, no pull-up required. |
| 2 VSO | SO output supply | Sets SO logic level (3.3 V or 5 V); also enables sleep mode when pulled to GND. |
| 3 SO | SPI serial output | Push-pull output; voltage referenced to VSO; carries diagnostic register data or error flag. |
| 4 VS | Main power supply input | 4.5–28 V operating range; powers internal regulators, charge pump, and output stages. |
| 5 OUT1 | H-bridge output 1 | High-current n-channel drain terminal; connects to one side of motor or inductive load. |
| 6 GND | Power and signal ground | Common reference for all circuits; electrically tied to exposed heat slug for thermal path. |
| 7 OUT2 | H-bridge output 2 | High-current n-channel drain terminal; complements OUT1 to complete full H-bridge topology. |
| 8 SI | SPI serial input | Receives command and configuration data (e.g., fault mask settings) from MCU. |
| 9 CSN | SPI chip select (active low) | Enables SPI communication only when low; allows shared SCK/SI/SO bus with other peripherals. |
| 10 SCK | SPI clock input | Drives synchronous data transfer; max 1 MHz supported per datasheet timing specs. |
| 11 DIS | Disable input | Forces all MOSFETs OFF (tristate); overrides PWM/DIR; active-high, CMOS-compatible. |
| 12 PWM | Pulse-width modulation input | Controls duty cycle of motor drive; combined with DIR determines speed and direction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Eliminates external bootstrap capacitor; ensures stable high-side gate drive across full VS range (4.5–28 V). |
| Configurable SO logic level | VSO pin selects 3.3 V or 5 V SO output - matches host MCU I/O voltage without level shifters. |
| Chopper current limitation | Automatically cycles H-bridge at ~10 kHz when load current exceeds 8 A typ., limiting thermal stress. |
| Open-load detection in PWM mode | Detects broken wire or disconnected motor even during active PWM switching - critical for safety-critical actuators. |
| Latched fault protection | Shuts down outputs until DIS or VSO reset; prevents uncontrolled restart after fault condition clears. |
Applications
| Automotive HVAC Actuators | Electronic Power Door Locks |
|---|---|
|
Use Scenario: Precise bidirectional positioning of blend-air flaps and mode doors in climate control systems. IC Role / Device Role / Timing Role: H-bridge driver executing PWM/DIR commands from body controller MCU; provides current feedback and fault status via SPI.

IC Role / Device Role / Timing Role: Bidirectional load driver with fast enable/disable (DIS) and open-load verification before actuation. Use Value: Confirms solenoid integrity prior to energization, preventing false lock/unlock events due to wiring faults. |
| Seat Position Adjusters | Engine Cooling Fan Control |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9201SG | Automotive-qualified (AEC-Q100 Grade 1); identical pinout and SPI register map; higher ESD rating (±8 kV HBM). | Required for production automotive ECUs; supports extended temperature range (−40 to +150 °C ambient). | Select when full automotive qualification and extended temp operation are mandatory. |
| VNH7040ASTR-E | 42 V max VS; higher RDS(on) (140 mΩ); no SPI - only error flag and analog current sense output. | Better suited for 24 V commercial vehicles; lacks register-level diagnostics but offers analog current monitoring. | Choose for cost-sensitive 24 V systems where SPI is unnecessary and analog sensing suffices. |
Compared with TLE9201SG and VNH7040ASTR-E, IFX9201SGAUMA1 balances diagnostic depth and thermal robustness for non-automotive industrial and premium consumer applications - offering SPI visibility without AEC-Q100 overhead or analog-only trade-offs.

FAQ
Can IFX9201SGAUMA1 operate from a 5 V supply?
No - the VS supply range is specified from 4.5 V to 28 V, but operation at 5 V is not recommended due to insufficient headroom for internal regulation and charge-pump operation. Minimum reliable VS is 6 V for stable functionality across temperature and load; typical use starts at 12 V for automotive and industrial 12 V systems.
Does IFX9201SGAUMA1 support regenerative braking?
No - the device lacks synchronous rectification or configurable shoot-through prevention for controlled energy recovery. It supports freewheeling (via PWM=0) and braking (via reverse polarity), but does not provide active current reversal or voltage boosting needed for true regeneration.
How is open-load detection performed during PWM operation?
Open-load detection runs continuously during PWM cycles by injecting brief test pulses into the inactive half-bridge while monitoring voltage decay at OUT1/OUT2. It distinguishes open circuit from high-impedance loads using time-domain response thresholds - validated in both ON and OFF states per datasheet Section 4.11.
Is the PG-DSO-12-17 package lead-free and RoHS compliant?
Yes - the IFX9201SGAUMA1 uses a lead-free PG-DSO-12-17 package conforming to RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), with halogen-free molding compound and NiPdAu lead finish.
