TLE9180D31QKXUMA1 概述
A half-bridge gate driver is a power-management IC that translates low-power PWM logic signals from a microcontroller into high-current gate-drive voltages capable of rapidly switching large power MOSFETs. It sits between the MCU (control domain) and the inverter power stage (power domain), forming one of the cornerstones of every modern motor-drive or DC-DC converter. The TLE9180 family extends this concept with built-in protection, current sensing and ASIL-aware diagnostics, removing many external components.
Key features include six half-bridge channels, programmable dead-time control, integrated charge-pump ready for 100% PWM duty, 5.5 V to 60 V supply range, current-sense amplifier for shunt-based phase-current measurement, and a comprehensive protection set: under-voltage, over-voltage, over-temperature, short-circuit, and cross-conduction prevention. SPI interface provides configurable fault and diagnostic readback. The LQFP-64-EP package exposes a thermal pad that drops theta_JA well below a standard LQFP, easing thermal design at 1 A continuous gate current.
Typical applications include 12V/24V/48V BLDC and PMSM motor drives for electric water pumps, oil pumps, fans, HVAC blowers, e-bike traction controllers, and mild-hybrid auxiliary drives. Designers also use it for high-current three-phase solenoid drivers and DC-DC converter synchronous-rectifier control. The 90 V transient tolerance provides headroom for load-dump events in 24 V truck systems.
When designing with this IC, ensure the bootstrap capacitors are sized for the maximum PWM period to maintain VGS above the MOSFET Miller plateau. The exposed pad must be soldered to a continuous ground copper pour to keep junction temperature within the -40C to +150C automotive Grade-1 range. Use the SPI window for cyclic diagnostics to meet ASIL requirements.
This page consolidates real-time distributor pricing, qualified drop-in alternatives within the TLE9180 family and competing gate drivers, and practical design notes that complement the Infineon datasheet for faster automotive motor-drive design.

典型应用
TLE9180D31QKXUMA1 适用于 6 应用s: Automotive Electric Water Pump, 48V Mild-Hybrid BLDC Traction Drive, HVAC Blower and Cooling Fan, E-Bike / Light Electric Vehicle Motor Controller, Automotive Oil Pump and Vacuum Pump, Industrial Servo and 3-Phase DC-DC Synchronous Rectifier.
Automotive Electric Water Pump
The TLE9180D31QKXUMA1 is purpose-built for 12V-48V automotive BLDC water pumps where thermal management of the engine and power electronics is critical. Its 1A source/sink gate-drive current switches 60V-100V MOSFETs at high PWM frequency, enabling FOC control with up to 30kHz switching and 100% duty-cycle pump-down operation. The integrated current-sense amplifier eliminates a discrete op-amp and shunt-front-end, reducing BOM and PCB area. ISO 26262 compliance supports ASIL-B/C water-pump safety goals and the -40C to +150C Grade-1 range covers under-hood ambient. Compared with discrete three-phase driver solutions, the TLE9180D31QKXUMA1 shrinks the inverter footprint by roughly 40%.
推荐
48V Mild-Hybrid BLDC Traction Drive
The TLE9180D31QKXUMA1 supports 48V mild-hybrid traction drives up to several kW where 90V transient tolerance and 60V nominal supply are mandatory. Its six half-bridge channels drive the 3-phase inverter of a mild-hybrid e-machine, while the integrated current-sense amplifier provides phase-current feedback for FOC at >20kHz loop bandwidth. The SPI diagnostic interface reports per-channel fault status (over-current, short-to-ground, short-to-battery) for ASIL-rated functional safety. Junction temperature stays in range thanks to the exposed-pad PG-LQFP-64 package, which the design accommodates with a continuous ground copper pour. For higher-power drives, two TLE9180D31QKXUMA1 in paralleled inverter stages are also possible.
推荐
HVAC Blower and Cooling Fan
HVAC blower motors in passenger vehicles increasingly use BLDC for efficiency and silent operation, and the TLE9180D31QKXUMA1 fits perfectly for 12V/24V blower drives. Its non-inverting gate outputs match standard N-channel MOSFET half-bridges, and the programmable dead-time control prevents cross-conduction that would otherwise cause shoot-through and EMI. The integrated charge pump maintains high-side gate drive at 100% duty, so the blower can hold full speed regardless of battery voltage sag. The 1A source/sink capability enables switching frequencies above 25kHz, pushing acoustic noise above the audible range. ASIL-rated diagnostics support HVAC safety goals in modern vehicles.
推荐
E-Bike / Light Electric Vehicle Motor Controller
The TLE9180D31QKXUMA1 is well-suited for 24V/36V/48V e-bike and light-EV traction motor controllers, where 1A gate-drive current switches the inverter MOSFETs at high PWM frequency for smooth torque control. Its integrated current-sense amplifier provides phase-current feedback for torque-vector control algorithms while the SPI interface enables tunable throttle response, regenerative-braking profiles, and diagnostic logging. The exposed-pad LQFP-64 package keeps the junction cool even in sealed enclosures, and the -40C to +150C range handles outdoor summer-winter extremes. A single TLE9180D31QKXUMA1 plus a small MCU replaces discrete three-half-bridge driver ICs.
推荐
Automotive Oil Pump and Vacuum Pump
Variable-speed automotive oil pumps and vacuum pumps benefit from the TLE9180D31QKXUMA1's BLDC drive capability, integrated current sensing, and full automotive Grade-1 qualification. Switching 60V MOSFETs at 1A drive strength delivers fast current-loop response for tight pressure regulation. SPI diagnostics report over-temperature and over-current faults to the ECU for predictive maintenance and limp-home strategies. The wide 5.5V-60V supply range handles cranking transients and load-dump spikes without external protection circuits.
推荐
Industrial Servo and 3-Phase DC-DC Synchronous Rectifier
Beyond automotive, the TLE9180D31QKXUMA1 also drives industrial 3-phase servo inverters up to 60V, and the six half-bridge channels can be re-purposed as synchronous-rectifier drivers for high-current isolated DC-DC converters. Its 1A gate-drive current switches large MOSFET arrays with low loss, and the integrated current-sense amplifier provides accurate cycle-by-cycle current telemetry. The LQFP-64 exposed-pad layout supports continuous industrial duty cycles at elevated ambient temperatures, while the SPI interface enables real-time telemetry of fault status, junction temperature, and supply voltage.

设计说明
The PG-LQFP-64-27 exposed pad must be soldered to a continuous ground copper pour with at least 6 thermal vias (0.3 mm drill, 0.5 mm pitch) under the pad. Estimated: with 4-layer PCB (1oz outer, 2oz inner) and continuous ground plane, theta_JA drops to roughly 25 C/W, supporting continuous 1A gate-drive operation in -40C to +125C environments. For under-hood applications exceeding +105C ambient, verify junction temperature with the Infineon thermal model.
Place the bootstrap capacitors (typically 100 nF to 1 uF X7R ceramic) as close as possible to each BST/VBS pin pair. Keep the high-side gate-drive loop (GH-SH-BST-GND) shorter than 5 mm to minimize parasitic inductance that can otherwise overshoot VGS above the MOSFET VGS(max) rating. Use a star-ground connection from each low-side source sense to the central GND pin to avoid ground bounce in the current-sense amplifier.
Do not exceed 90 V transient on bridge, motor or supply pins even though the nominal VS range is 5.5 V to 60 V; load-dump in 24V truck systems can exceed 90 V. Place a TVS diode (e.g. 66V bidirectional) at the VS pin for 24V systems. The integrated charge pump supports 100% duty, but if the pump is disabled in low-power mode, ensure PWM duty does not exceed the bootstrap refresh interval or the high-side gate will collapse.
Route the SPI signals (CSN, SCLK, SDI, SDO) over a continuous ground reference and away from the gate-drive switching nodes; gate transitions on GH/GL edges can couple into SPI lines and corrupt register writes. Place a 10 kohm pull-up on CSN and 100 ohm series termination on SCLK/SDO/SDI when the SPI bus runs longer than 50 mm. Decouple VS with at least 10 uF X7R ceramic plus a 100 uF electrolytic for bulk hold-up during cold-crank events.
