TLE9180D32QKXUMA1 - 6-Ch BLDC Gate Driver 90V LQFP-64 | Infineon
MPN: TLE9180D32QKXUMA1 ✓ Hoạt độngTLE9180D32QKXUMA1 Tóm tắt
A gate driver IC (also called a MOSFET driver or predriver) is a power-management building block that translates low-current logic-level control signals from an MCU into the high peak currents required to rapidly charge and discharge a power MOSFET gate. In the system hierarchy, gate drivers sit between the microcontroller and the power stage: MCU -> gate driver -> power MOSFETs -> motor. Compared with discrete bootstrap drivers, an integrated multi-channel gate driver such as the MOTIX TLE9180D-32QK dramatically reduces BOM count, improves timing skew between high-side and low-side channels, and centralizes protection functions.
Key features of this part include support for battery voltages from 5.5 V to 72 V, programmable gate drive currents up to 1 A source/sink, integrated current-shunt amplifier with adjustable gain, and ASIL-C functional safety support per ISO 26262. The device targets safety-relevant applications and is qualified to AEC-Q100 for automotive use.
Typical applications are automotive electric water pumps, oil pumps, e-bike and e-scooter traction drives, 48 V mild-hybrid auxiliary drives, BLDC fans and blowers for HVAC, and small industrial 3-phase pumps. The wide input range allows a single PCB design to support both 12 V passenger-vehicle platforms and 48 V commercial-vehicle or mild-hybrid systems, reducing platform SKU count for tier-1 suppliers.

Ứng dụng tiêu biểu
TLE9180D32QKXUMA1 phù hợp cho 6 Áp dụngs: Automotive Electric Water Pump, 48 V Mild-Hybrid Auxiliary Drives, E-Bike and E-Scooter BLDC Traction, HVAC BLDC Fans and Blowers, Industrial 48 V Three-Phase Pumps, Automotive Engine Oil Pump.
Automotive Electric Water Pump
The TLE9180D32QKXUMA1 is ideal for automotive electric water pumps because its 5.5 V to 72 V supply range covers both 12 V passenger-vehicle and 48 V mild-hybrid cooling loops on a single PCB design. The integrated current-sense amplifier directly interfaces with a low-ohm shunt resistor, eliminating the external op-amp that discrete driver solutions require. SPI diagnostics report over-current, over-temperature, and VS under-voltage to the host MCU, which lets the ECU shut the pump down on coolant overtemperature conditions - critical for ASIL-C functional safety. The 1 A gate drive current source/sink rapidly commutates the 40 V MOSFETs typically used at 12 V or the 80 V MOSFETs required at 48 V, minimizing switching losses at 25 kHz PWM.

48 V Mild-Hybrid Auxiliary Drives
For 48 V mild-hybrid systems, the TLE9180D32QKXUMA1's 90 V transient pin tolerance directly handles load-dump events on the 48 V bus that discrete drivers cannot survive without external TVS clamping. The integrated charge pump supplies the high-side gate drive for 100% duty cycle operation, enabling regenerative braking torque control that bootstrap-based designs cannot achieve. ASIL-C support matches the safety goals of mild-hybrid motor-generator units, and the SPI watchdog allows the safety MCU to verify driver health every 10 ms. Per the Infineon datasheet, junction temperatures up to 150 C support underhood placement.

E-Bike and E-Scooter BLDC Traction
The TLE9180D32QKXUMA1 serves e-bike and e-scooter traction motor controllers because the 5.5 V to 72 V supply range matches both 36 V and 48 V battery packs without changing the PCB. AEC-Q100 qualification gives designers headroom for vibration and thermal stress beyond consumer-grade parts, important for outdoor IP-rated enclosures. The SPI interface supports torque-profile calibration via firmware, enabling different riding modes without changing hardware. The integrated current-shunt amplifier with adjustable gain lets the same board handle 10 A city riding and 30 A peak assist.

HVAC BLDC Fans and Blowers
For HVAC BLDC fans and blowers, the TLE9180D32QKXUMA1's small 10x10 mm LQFP-64 footprint fits the slim housings required by modern instrument-panel and seat-ventilation modules. The 3-phase sinusoidal commutation supported by the SPI-driven PWM inputs produces the low acoustic noise passengers expect from premium cabin comfort systems. Diagnostic features including stall detection via current sense and overtemperature shutdown allow the HVAC ECU to detect a blocked blower wheel without an external sensor, reducing wiring harness cost. The 1 A gate drive handles the 60 V MOSFETs used at 48 V supply.

Industrial 48 V Three-Phase Pumps
Industrial 48 V three-phase pumps benefit from the TLE9180D32QKXUMA1's wide supply range that allows a single SKU to address 24 V forklift hydraulics and 48 V automated guided vehicles. The integrated current-sense amplifier and SPI fault reporting let the industrial PLC implement closed-loop flow control without an external analog front-end. ASIL-C capability exceeds typical industrial functional-safety requirements, future-proofing designs that migrate to higher SIL targets. According to the Infineon datasheet, the part operates from -40 C to +150 C junction, suitable for outdoor pump stations.
Được đề xuất
Automotive Engine Oil Pump
Variable-displacement engine oil pumps require precise torque control to reduce parasitic losses, which the TLE9180D32QKXUMA1 supports through SPI-programmable PWM duty cycle and current-sense feedback. Underhood placement demands the 150 C junction temperature rating and AEC-Q100 qualification this part provides. The 90 V transient tolerance handles inductive spikes from the oil pump motor windings during commutation. Integration of three half-bridge drivers plus a charge pump reduces PCB area by approximately 40% versus discrete bootstrap designs, important for integration into tight engine accessory housings.

Ghi chú thiết kế
Estimated: at continuous 1 A gate drive per channel with 6 channels active at 50% duty, internal gate-drive dissipation is approximately 0.5 W with 20 nC MOSFETs at 25 kHz. The PG-LQFP-64-27 package theta_JA is roughly 35 C/W on a 4-layer JEDEC EIA/JESD51 test board, giving a 17 C rise above ambient. For underhood placement at 85 C ambient, the junction temperature reaches 102 C - well below the 150 C limit. The exposed pad MUST be soldered with at least 8 thermal vias (0.3 mm drill) to the inner ground pour to achieve this performance; omitting the EP solder connection will push theta_JA above 60 C/W.
Per the Infineon datasheet, place the charge pump flying capacitor (CP1-CP2) within 5 mm of pins 4 and 5 with traces shorter than 10 mm to minimize parasitic inductance that reduces charge pump efficiency. Keep the current-sense amplifier traces (CSP, CSN) as a tight differential pair routed away from GH/SH switching nodes - crossover coupling above 30 dB will inject switching noise into the shunt measurement and corrupt torque control. Use 0402 or 0603 components for the gate-source resistors to minimize parasitic inductance.
Do not apply VS voltage before VDD is ramped up - the TLE9180D32QKXUMA1 requires VDD (5 V) stable before VS to avoid undefined SPI states and potential latch-up. Per Infineon, the SPI watchdog timer default is 256 ms - extend to 1024 ms if the host MCU has long interrupt latency. The motor pins (SH1/SH2/SH3) tolerate negative transients up to -7 V but exceeding this will damage the IC; add a TVS clamp on each phase node for highly inductive loads above 30 A peak.
