IFX007TAUMA1 - 40A Half-Bridge Motor Driver | Infineon NovalithIC
MPN： IFX007TAUMA1 ✓ 啟用中IFX007TAUMA1 概覽
A half-bridge (H-bridge half) driver is a power-management IC that combines one low-side and one high-side power MOSFET with their gate-drive circuitry on a single die, enabling bidirectional current control through a load (such as a motor winding) using only two external logic-level control signals. The half-bridge belongs to the broader category of full, half-bridge (H-bridge) drivers within PMIC (Power Management IC) products, which sit above discrete MOSFET driver + power MOSFET designs in the power-electronics hierarchy and below fully integrated motor-driver SoCs that include microcontrollers or predrivers.
Key features include 5.5 V to 40 V operating voltage, 12.8 mΩ typical RDS(on) per MOSFET, integrated charge pump for the high-side gate drive, logic-level inputs (IN = 1.6 V to 2 V high / 1.1 V to 1.3 V low), PWM capability up to 25 kHz, status flag output, and protection functions including over-temperature shutdown, over-current latch, under-voltage lockout, and short-circuit detection. The PG-TO263-7-1 package exposes the tab as the power ground/drain thermal pad, providing a low thermal resistance path suitable for continuous high-current operation.
Internally the IFX007T uses Infineon's proprietary smart power technology combining vertical p-channel high-side and vertical n-channel low-side MOSFETs with a CMOS/BCD control section on the same silicon. This monolithic integration eliminates the parasitic inductance and gate-loop inductance found in discrete half-bridge designs, dramatically reducing switching losses, ringing, and EMI. The integrated charge pump generates the high-side gate-drive voltage rail from the logic supply, allowing true 100 % duty-cycle operation and low-side freewheeling. Current sensing is performed by monitoring the low-side MOSFET RDS(on), eliminating an external shunt resistor.
Typical applications include DC motor control (brushed DC and BLDC with external commutation), solenoid and valve drivers, industrial automation actuators, automotive body and powertrain actuators, and battery-powered tools. When designing with this part, ensure adequate copper area on the exposed tab for thermal dissipation - at 30 A continuous the package can dissipate several watts - and follow Infineon's PCB layout guidelines to keep the bootstrap capacitor loop short for reliable high-side switching.

典型應用
IFX007TAUMA1 適用於 7 應用s: Brushed DC Motor Drive (H-Bridge), Automotive Body Actuators, Industrial Solenoid and Valve Driver, Battery-Powered DC Tools and Pumps, BLDC Motor Commutation (External Logic), Robotics and CNC Actuators, Solar Tracking and Tilt Mirrors.
Brushed DC Motor Drive (H-Bridge)
Two IFX007TAUMA1 devices wired as a full H-bridge deliver bidirectional control of a brushed DC motor up to 40 A continuous from a 12 V or 24 V supply. The 12.8 mΩ RDS(on) keeps conduction loss below 5 % at 20 A, while the 25 kHz PWM capability enables smooth torque control. The integrated over-temperature and over-current latch protects the motor and PCB during stall conditions, replacing a discrete design that needs 6 MOSFETs and 2 gate drivers.
推薦
Automotive Body Actuators
The IFX007TAUMA1 is AEC-Q100 qualified and operates from 5.5 V to 40 V, making it ideal for 12 V automotive body actuators such as HVAC doors, seat adjusters, window lifters, and throttle valves. Integrated protection (OT, OC, UVLO) eliminates the need for external fuses on the load, and the PG-TO263-7-1 package with exposed tab handles the thermal load of continuous 15-25 A operation. Per the Arrow listing, this part is explicitly marketed for automotive H-bridge applications.
推薦
Industrial Solenoid and Valve Driver
The IFX007TAUMA1's 40 A peak and low RDS(on) of 12.8 mΩ drive proportional hydraulic and pneumatic solenoid valves directly from a 24 V industrial bus, replacing mechanical relays that suffer from contact bounce. The integrated status output flags open-load and short-circuit faults to the PLC, while PWM control on the IN pin enables dithering for low-stiction valve response. The exposed-tab package handles the thermal dissipation of continuous 100 % duty cycle industrial operation.
推薦
Battery-Powered DC Tools and Pumps
Cordless drills, saws, and water pumps running from 18 V to 36 V battery packs benefit from the IFX007TAUMA1's 5.5 V to 40 V range and 90 %+ efficiency at full load. The integrated reverse-battery protection via the p-channel high-side MOSFET saves a Schottky diode, and 25 kHz PWM capability enables soft-start and current limiting for motor protection. The compact PG-TO263-7-1 footprint fits inside tight tool-handle enclosures.
推薦
BLDC Motor Commutation (External Logic)
Pair the IFX007TAUMA1 with an external microcontroller or sensorless commutation IC to drive brushless DC motors in fans, e-bikes, and small appliances. The half-bridge topology allows three IFX007TAUMA1 devices to form a complete 3-phase inverter for motors up to 40 A phase current. The 1.6 V to 2.0 V logic thresholds are directly compatible with 1.8 V MCUs, eliminating level shifters.
推薦
Robotics and CNC Actuators
The IFX007TAUMA1 drives brushed servo motors, lead-screws, and linear actuators in 24 V robotics and CNC machines. The integrated current sensing via low-side RDS(on) eliminates external shunt resistors, simplifying the BOM, while the open-drain status output enables real-time fault reporting over CAN or RS-485. The 12.8 mΩ RDS(on) keeps heat-sinking requirements modest for the typical 10-15 A continuous currents in this application.
推薦
Solar Tracking and Tilt Mirrors
Solar tracker panels and heliostat mirror arrays use the IFX007TAUMA1 to drive 24 V brushed gear-motors for sun-tracking. The 5.5 V to 40 V range handles variable battery states of charge, and the low quiescent current during off-state reduces night-time battery drain. The PG-TO263-7-1 package survives outdoor thermal cycling from -40 °C to +85 °C ambient when mounted with adequate copper on the tab.

主要差異化特點

設計說明
Estimated: at 24 V supply, 6 V motor drop, and 30 A continuous load, the IFX007TAUMA1 dissipates roughly 30 A × 0.025 V = 0.75 W conduction plus switching losses, totaling ~5 W. With the PG-TO263-7-1 thermal resistance of approximately 40 °C/W on a JEDEC 2s2p board, junction rise is 200 °C, so at least 2 square inches of 2 oz copper on the exposed tab is required. Designers targeting 40 A continuous must use 6+ square inches of copper plus forced-air cooling.
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VS pin to suppress switching ringing, and a 10 µF bulk capacitor on VS to handle motor back-EMF. Route the OUT trace with at least 4 mm width (1 oz copper) or use a copper pour, and stitch vias around the GND tab with 0.3 mm pitch to reduce thermal resistance. The exposed tab MUST be soldered to the PCB for both electrical ground and thermal path - dry solder joints will overheat.
Do not operate below 5.5 V VS - the under-voltage lockout will chatter and the high-side charge pump will not develop sufficient gate voltage. Do not drive the IN pin with a 1.8 V signal whose tolerance could drop below 1.1 V; ensure logic-level drive is firmly above 2.0 V. The status flag (ST pin) is open-drain and requires a pull-up to VCC. Reverse-battery protection is NOT included externally - add a P-MOSFET on VS for reverse-polarity safety on automotive designs.
Keep the IN trace short (≤25 mm) and routed away from the OUT switching node to avoid logic glitches from capacitive coupling. For H-bridge configurations using two IFX007TAUMA1 devices, place them in mirror symmetry around the motor terminal so the high-side return loops (VS→high-side→OUT→load→GND) are physically balanced. Refer to Infineon application note "NovalithIC Layout Guidelines" for the full PCB stack-up recommendation.
