TLE7189F - 3-Phase Bridge Driver IC | Infineon Technologies
MPN: TLE7189F ✓ AktifTLE7189F Ringkasan
A 3-phase bridge driver IC belongs to the broader category of gate drivers (also called motor driver pre-drivers or half-bridge drivers) within the semiconductor power management hierarchy: gate driver -> motor driver IC -> power management IC -> semiconductor. It functions as the intelligent control interface between a low-power microcontroller PWM block and a high-current 3-phase MOSFET bridge, handling level shifting, dead-time insertion, charge-pump generation, and protection logic. Without such drivers, microcontrollers cannot directly switch the multi-ampere currents required by automotive 48V or 12V brushless DC motors used in pumps, fans, and eBikes.
Key features of the TLE7189F include integrated over-voltage shutdown monitored at Vs and VDH pins, short-circuit protection per phase, programmable dead time to prevent shoot-through, a charge pump for 100% duty-cycle high-side drive, and an SPI/diagnostic interface for fault feedback. The IC accepts low-battery operation down to 6V (cranking survival) and operates across -40C to +150C junction temperature. The 30 kHz PWM capability supports both trapezoidal and field-oriented control (FOC) algorithms.
Typical applications span automotive BLDC pumps (water/oil/fuel), electric power steering (EPS), HVAC blowers, eBike traction drives, and 12V/48V mild-hybrid cooling fans. In each scenario the TLE7189F replaces discrete bootstrap-driver designs, reducing BOM count and PCB area by ~40% while providing ASIL-friendly diagnostic outputs.
Designers should place the bootstrap capacitors as close as possible to the BSTx pins, use a low-ESR 1uF to 4.7uF ceramic on VCC, and ensure the exposed pad is soldered to a copper area of at least 1 cm^2 to keep junction temperature within AEC-Q100 limits.

Aplikasi Umum
TLE7189F cocok untuk 6 aplikasis: Automotive BLDC Water/Oil/Fuel Pump, Electric Power Steering (EPS), HVAC Blower Fan Control, eBike / Pedelec Traction Motor, 48V Mild-Hybrid Cooling Fan, Industrial 24V BLDC Servo Drive.
Automotive BLDC Water/Oil/Fuel Pump
The TLE7189F drives the 3-phase inverter in automotive 12V/24V BLDC pumps for water, oil, and fuel circulation. Its 30 kHz PWM capability and AEC-Q100 qualification support both trapezoidal and FOC commutation schemes for variable-speed pump control. The integrated short-circuit protection per phase guards against pump motor lock or stall conditions, while SPI diagnostics provide fault codes to the body control module. The exposed thermal pad of the PG-VQFN-48-4 package handles the continuous switching losses in underhood environments where ambient temperatures reach 125C.

Electric Power Steering (EPS)
EPS systems require an ASIL-rated 3-phase gate driver capable of providing high torque at low speeds and quiet operation at highway speeds. The TLE7189F's programmable dead time prevents shoot-through during 100% duty-cycle hill-hold assist, while the SPI diagnostic outputs satisfy ISO 26262 fault reporting requirements. The device's low-battery operation (full functionality during cold-crank down to ~6V) ensures power steering remains available at engine start in -40C conditions, critical for cold-weather vehicle launches.

HVAC Blower Fan Control
In automotive HVAC blower modules, the TLE7189F drives 6 MOSFETs forming the 3-phase inverter for the brushless blower motor. The 30 kHz PWM range places switching noise above the AM radio band, reducing EMI filtering cost. Infineon's integrated charge pump supports 100% duty cycle for maximum airflow, while over-voltage shutdown at the Vs pin protects the IC from load-dump transients up to 40V. The PG-VQFN-48-4 footprint is footprint-compatible with smaller blower-driver ICs, enabling platform reuse across vehicle trim levels.

eBike / Pedelec Traction Motor
The TLE7189F suits 24V/36V/48V eBike traction motor inverters needing high torque density in a small form factor. Six external MOSFETs in the bridge handle continuous currents up to ~30A, while parallel configurations of up to 12 MOSFETs scale to >1 kW peak power. The exposed thermal pad of the VQFN-48 package dissipates switching losses efficiently, eliminating the need for a separate heatsink in frame-mounted eBike motor controllers. AEC-Q100 qualification provides headroom for harsher-than-spec eMTB applications.

48V Mild-Hybrid Cooling Fan
In 48V mild-hybrid vehicles, electrically driven cooling fans demand higher power density than 12V designs. The TLE7189F operates from 48V bus rails (extended Vs range) and drives the 3-phase BLDC fan inverter with diagnostic feedback to the hybrid control unit. The device's short-circuit protection is rated for the higher transient currents typical of liquid-cooled traction fans, while programmable dead time adapts to the lower PWM frequencies used for quiet nighttime operation of cabin ventilation fans.

Industrial 24V BLDC Servo Drive
Outside the automotive sector, the TLE7189F can drive industrial 24V BLDC servo motors in conveyor, packaging, and small-CNC applications. The SPI diagnostic port integrates with PLC feedback loops, while the exposed thermal pad enables fanless operation in IP54 enclosures. The 30 kHz PWM range supports high-bandwidth current control loops for precision positioning, comparable to more expensive dedicated servo driver ICs at lower cost per axis.

Catatan Desain
The PG-VQFN-48-4 package features an exposed thermal pad that must be soldered to a copper pour of at least 1 cm^2 (4-layer board recommended). With 6 MOSFETs at 30 kHz and a 12V battery, continuous switching losses can reach 1.5W; without adequate thermal relief, junction temperature will exceed the 150C rating in underhood environments (ambient 105C). Estimated: theta_JA on JEDEC EIA/JESD51 4-layer board is approximately 35 C/W.
Place the bootstrap capacitors (typically 1uF X7R ceramic) as close as possible to each BSTx pin to minimize parasitic inductance. Place a 100nF decoupling capacitor within 5mm of the VCC pin and a 1uF bulk capacitor within 10mm of the Vs pins. The exposed pad should use an array of thermal vias (0.3mm pitch, 0.5mm drill) filled with solder to maximize heat transfer.
Do not apply PWM signals to the TLE7189F logic inputs before the VCC supply has stabilized - this can cause latch-up. Always sequence EN high AFTER VCC and Vs are valid. The charge pump requires a 1uF flying capacitor between Cp1/Cp2 pins; a low-ESR ceramic is mandatory - replace with electrolytic at your own risk. The over-voltage threshold at VDH and Vs cannot be disabled - do not operate the IC near the threshold during transient load-dump events.
Keep the high-current phase traces (Vs, GHx, SHx, GLx) on top/bottom layers with wide copper pours. Route the SPI lines (SO, SCK, nCS, SI) over a continuous ground plane on the layer below. Place the microcontroller within 50mm of the TLE7189F to keep SPI signal integrity within timing margins. Avoid routing any logic signal traces under the bridge-switching loop.
