HEV/EV inverter & motor control

Isolated gate drivers

The gate driver provides galvanic isolation between input and output, drives the SiC or IGBT-based three-phase motor half bridges and enables monitoring of and protection against various fault conditions.

Benefits:

• Improve system-level efficiency: minimize switching and conduction losses that include turnon and turnoff energy.
• Increase power density: high drive strength helps lower the gate driver’s case temperature, mitigating the need for more expensive heat sinks or additional PCB ground. 
• Enhance reliability and safety: integrated IGBT/SiC health monitoring identifies early failures in power switches. Optimized diagnostics support highest functional safety rating (up to ASIL-D). 

Real-time control MCUs

Enable new architectures in the next generation of electrified vehicles with high-performance real-time control MCUs. These capabilities with < 4-us control loops (including resolver) and compute performance of 3.2k DMIPS enable:

• Increased driving range: Higher motor speeds (>20,000 RPM) reduce motor size and can extend driving distance per charge.
  
• Improved power density and efficiency: Better control loop bandwidth use and support for higher switching frequencies (>20kHz) unlocks the potential to use wide-bandgap technologies such as silicon carbide (SiC). 
• Streamlined functional safety certification: Functional safety features enable up to ASIL-D/SIL3 compliance, E-Safety Vehicle Intrusion Protected Applications (EVITA) and AUTOSAR support.

The right bias power supply solution

Optimize system cost while improving power density and efficiency to meet your system requirements. Choose from a comprehensive portfolio of devices with integrated FETs and magnetics, or integrated FETs and external magnetics and external FETs and external magnetics.

Benefits:

• Improve power density and efficiency with small footprint, >150V/ns CMTI, and superior EMI performance.
• Streamline functional safety with ISO26262 compliance and system level diagnostics and protection.
• Protect power modules with high load regulation accuracy and thermal performance.

Position sensing, isolated voltage and current sensing

Achieve accurate, low-latency current and voltage measurements with high common-mode transient immunity (CMTI) and working voltages, thereby improving system efficiency, reliability and performance of traction inverter systems.

Benefits:

• State-of-the-art capacitive isolation enhances safety and lowers system cost.
• Isolation amplifiers and modulators offer high bandwidth for faster control and reaction time that enables higher system reliability and better performance.
• High power amplifiers specifically designed for resolver excitation reduce the PCB footprint and eliminate the need for external protection.
