HB2000

Roll over image to zoom in

In line with the green revolution, electric motor control is moving very quickly in the direction of higher efficiency for motor drivers. The HB2000 features provide:

  • Safety and Protection: First NXP® H-Bridge motor driver designed using ISO 26262 processes in support of ASIL level C and D system qualification.
  • Efficient thermal management: Integrated MOSFETs with temperature dependent current limit scheme to prevent excessive heating of device.
  • Scalability: SPI programmable current limits and slew rates enable the use of the same motor driver for various motor sizes.
