Heating & cooling

Maximize driving range and lower cost of electric vehicles (EVs) with efficient system solutions for evolving EV thermal management architectures

In hybrid EVs (HEVs) and EVs, thermal-management systems are second only to powertrain systems in power consumption. Improving system-level efficiency for heating and cooling systems thus has a direct impact on driving range. Our technology and expertise help optimize energy-conversion efficiency and reduce power losses while improving the overall driving experience.

Why choose TI for your automotive heating and cooling system?

Scale across different platforms and reduce development cost

Scaling across different system voltages (48 V, 400 V and 800 V) is easier with real-time control MCUs, isolated gate drivers and power bias supplies, ranging from cost-efficient to high-performance.

Achieve low acoustic noise

A peripheral architecture allows designers to implement advanced commutation algorithms, resulting in low pulsation and low acoustic noise.

Enabling technologies

Real-time control MCUs

A range of memory footprints, packages, safety and cybersecurity enablers provide a scalable and compatible platform for automotive designers. Design smaller, more affordable automotive systems for a wide range of applications, from heating, ventilation and air-conditioning (HVAC) compressors to positive temperature coefficient (PTC) heater.

Microcontroller (MCU) benefits include:

  • Low noise, low vibration and high startup torque for sensorless motor-control applications.
  • Fast time-to-market and ease-of-use through software and hardware such as TIDM-02012 and InstaSPIN™ solutions.
  • A lockstep core that simplifies functional safety without software overhead.

Reliable gate drivers

We offer isolated and nonisolated gate drivers to reliably drive insulated-gate bipolar transistor (IGBT)- or silicon carbide (SiC)-based three-phase compressor half bridges and positive temperature coefficient load-control circuits.

Gate driver benefits include:

  • Isolation from unwanted transients and DC voltages for high-voltage systems.
  • Dual-channel drivers that reduce overall printed circuit board area and component count compared to single-channel devices.
  • Integrated Miller clamps that protect the system from false turnons caused by Miller current.
  • Extended supply-voltage ranges that provide sufficient margin for overshoot protection.
