TLE9561QXXUMA1 Overview
A motor driver IC is an integrated circuit that combines gate drivers, power MOSFETs, protection circuits, and a digital control interface (typically SPI) into a single package. Motor drivers sit at the bottom of the power-management hierarchy: BLDC driver IC -> motor driver -> power management IC -> semiconductor. By integrating the half-bridge stages and a 5V/3.3V supply, the TLE9561QX eliminates the need for separate gate-driver ICs and external LDO regulators in compact mechatronic modules.
Key features include SPI-controlled half-bridges for three-phase BLDC motors, an integrated linear voltage regulator supplying 5V at up to 250 mA, watchdog and fail-safe logic, low quiescent current in stop mode, and AEC-Q100 qualification for automotive environments. The device operates across a wide 5.5V to 28V battery supply range with transient tolerance up to 40V, supporting 12V automotive rails.
At the architecture level, the device combines an ARM-compatible embedded power controller with high-side and low-side charge-pump-driven N-channel MOSFET outputs. The SPI interface allows parametrization of current limits, dead times, slew rates, and diagnostic thresholds. Thermal shutdown, overcurrent, open-load, and short-to-ground/battery diagnostics are multiplexed back to the microcontroller through the same SPI bus, enabling predictive maintenance.
Typical applications include HVAC blowers, engine cooling fans, water/oil pumps, e-compressors, electric power steering (EPS) auxiliary drives, and any small three-phase BLDC actuator in a 12V automotive board net. The wide Vin range also supports 24V mild-hybrid subsystems.
When designing with this device, ensure that the exposed pad is soldered to a sufficient copper area for thermal dissipation. Use the SPI watchdog to detect microcontroller lockups and place the decoupling capacitors as close as possible to the supply pins to suppress switching noise.

Typical Applications
TLE9561QXXUMA1 is suitable for 7 applications: Automotive HVAC Blower Motor, Engine Cooling Fan (Radiator Fan), Electric Water/Oil Pump, HVAC E-Compressor (Refrigerant Compressor), Auxiliary Electric Power Steering (EPS) Drives, Industrial 24V Three-Phase Small Drives, Electric Two-Wheeler / E-Bike Drive (12V Aux Motor).
Automotive HVAC Blower Motor
The TLE9561QXXUMA1 directly drives a three-phase BLDC blower motor in HVAC modules from a 12V board net. With three integrated half-bridges, SPI-commanded PWM, and a 5V/250 mA LDO that powers the host MCU, the IC eliminates the external gate-driver and LDO typically required for such designs. Per the Infineon datasheet, the 5.5-28V supply range (40V transient) tolerates load-dump events on the 12V rail, while the -40 to +150 C junction rating supports under-dash mounting. Integrated diagnostics (open-load, short-to-GND, short-to-VBAT) feed back through SPI for ASIL-aware fault handling.
Recommended
Engine Cooling Fan (Radiator Fan)
The TLE9561QXXUMA1 drives a high-current three-phase radiator-cooling fan up to several amps per phase (datasheet figure). Its integrated charge pump and gate drive supply ensure full enhancement of the N-channel high-side MOSFETs at low battery voltage (cold-crank at 5.5V). AEC-Q100 qualification and the wide Vin tolerance make the part suitable for under-hood mounting, where ambient temperatures exceed 125 C. The IC's overcurrent and overtemperature protection helps the ECU implement graceful degradation when airflow is restricted by debris or bearing wear.
Recommended
Electric Water/Oil Pump
The TLE9561QXXUMA1 is well-suited to three-phase BLDC coolant and oil pumps in 12V automotive systems. Its 5V LDO can power a small host MCU or CAN-transceiver companion, reducing BOM by one regulator. The exposed-pad PG-VQFN-48-31 package dissipates pump-class currents when mounted on a PCB thermal land of >=50 mm^2 of 2 oz copper. SPI-programmable current limits let the ECU adapt torque to coolant temperature, while open-load detection identifies air-pocket or cavitation events without external sensors.
Recommended
HVAC E-Compressor (Refrigerant Compressor)
For 12V e-compressors in electric-vehicle HVAC loops, the TLE9561QXXUMA1 integrates the three half-bridges, charge pump, and 5V supply needed to drive a high-speed three-phase BLDC compressor. AEC-Q100 and 150 C operation suit the under-bonnet thermal environment. The SPI interface allows the inverter controller to command torque at kilohertz PWM rates, while the device's short-to-ground and short-to-battery diagnostics protect the power stage during compressor stall events, which are common at refrigerant startup.
Recommended
Auxiliary Electric Power Steering (EPS) Drives
The TLE9561QXXUMA1 supports small three-phase auxiliary EPS motors in 12V systems, such as column-adjust or steering-wheel vibration actuators. Its integrated half-bridges and SPI provide a compact inverter footprint, while the 5V LDO powers a host MCU that runs the position-control loop. Although the device is not a primary ASIL-D EPS part, it serves in auxiliary steering subsystems where AEC-Q100 reliability and -40 to +150 C operation are required.
Recommended
Industrial 24V Three-Phase Small Drives
Beyond automotive, the TLE9561QXXUMA1's 5.5-28V (40V transient) supply range fits small industrial 24V three-phase BLDC drives such as small pumps, blowers, and conveyor rollers. The 5V LDO supplies an external MCU or sensor, and the SPI interface enables parameter storage and firmware updates on the factory floor. The exposed-pad VQFN-48 supports surface-mount assembly on FR4 PCBs, making it a candidate for compact industrial modules where automotive-grade reliability is a bonus.
Recommended
Electric Two-Wheeler / E-Bike Drive (12V Aux Motor)
The TLE9561QXXUMA1 drives small three-phase 12V BLDC auxiliary drives in electric two-wheelers, such as headlamp coolers, fan motors, or small hydraulic pumps. The SPI interface allows the central ECU to command torque and read back diagnostics over the vehicle CAN bridge. The PG-VQFN-48-31 surface-mount package supports compact control boards, while AEC-Q100-grade reliability handles the vibration and thermal stress typical of two-wheeler body integration.

Key Differentiators
- All-in-one BLDC motor driver IC with integrated 5V LDO and SPI in a single PG-VQFN-48-31 package (vs Discrete gate-driver + external LDO + half-bridge MOSFET approach)
- AEC-Q100 qualified for automotive 12V board-net BLDC applications (vs TLE42062GXUMA2 (brushed DC driver))
- Wide Vin tolerance (5.5-28 V, 40 V transient) covers cold-crank and load-dump on 12V rails (vs Discrete MOSFET bridges without integrated transient protection)
Design Notes
Estimated: at continuous per-phase current of 2 A and 12V supply into a BLDC motor at 50% duty, the TLE9561QXXUMA1 dissipates roughly 1-2 W internally. The PG-VQFN-48-31 package relies on the exposed pad; solder it to a PCB thermal land of at least 50 mm^2 of 2 oz copper. Without this copper area, junction temperature can exceed the 150 C limit and trigger thermal shutdown.
Place the supply decoupling capacitors (typically 100 nF ceramic plus 10 uF bulk) as close as possible to the VS and VCC pins of the TLE9561QXXUMA1. Keep the high-current half-bridge traces short and wide to minimize parasitic inductance; otherwise, the 40 V transient rating may be exceeded during PWM switching. Use a four-layer PCB with a dedicated ground plane directly beneath the IC to provide both thermal spreading and low-impedance return paths.
Do not omit the SPI watchdog configuration in firmware; without it, a host-MCU lockup will leave the motor driver in its last state, which can be hazardous for pumps or fans. The exposed pad must be soldered - a dry solder joint will cause the thermal resistance to rise dramatically and may lead to thermal-shutdown cycling under load. Confirm the charge-pump capacitor value matches the datasheet's recommended 100 nF to 220 nF X7R ceramic, since undersized capacitance reduces gate-drive headroom at low battery voltage.
Route the SPI traces (SDI, SDO, SCLK, CSN) as a bus with controlled impedance and keep them away from the high-current half-bridge traces. Place a small RC filter (e.g., 100 ohm + 100 pF) on the CSN line if the SPI bus is long (>50 mm) to suppress ringing. The CSN pin doubles as the device enable; ensure the host MCU drives CSN high in its reset state to disable the driver until firmware is ready.
