SPI-Programmable H-Bridge Brushed DC Motor Driver

HB2002

Roll over image to zoom in

The HB2002 meets shifting demands for motor control applications in automotive and industrial spaces, delivering the efficient and robust performance necessary for tomorrow's safety-critical solutions.

  • Safety and Protection: H-Bridge motor driver designed using ISO 26262 processes to support ASIL C and D system qualifications.
  • Scalability: SPI-programmable current limits, slew rates, fault reporting, and control schemes enable the same IC to service various applications and motor sizes.
  • Thermal Management: Integrated power MOSFETs have temperature-dependent current limit foldback to reduce power and prevent excessive device heating.
