MC33HB2001EK

马达/运动/点火控制器和驱动器 H-Bridge, SPI, 5-28V 10A, Cur FB, SM-8

10 A H-Bridge, SPI programmable brushed DC motor driver

General description MC33HB2001EK

The 33HB2001 is a SMARTMOS monolithic H-Bridge Power IC, enhanced with SPI configurability and diagnostic capabilities. It is designed primarily for DC motor or servo motor control applications within the specified current and voltage limits.

This part is designed to specifically address the ISO 26262 safety requirements.

Features and benefits MC33HB2001EK

• Advanced diagnostic reporting via a serial peripheral interface (SPI): charge pump undervoltage, overvoltage, and undervoltage on VPWR, short to ground and short to VPWR for each output, open load, temperature warning and overtemperature shutdown

• Thermal management: Excellent thermal resistance of <1.0 °C/W between junction and case (exposed pad)

• Eight selectable slew rates via the SPI: 0.25 V/μs to more than 16 V/μs for EMI and thermal performance optimization

• Four selectable current limits via the SPI: 5.4/7.0/8.8/10.7 A covering a wide range of applications

Applications MC33HB2001EK

• Electronic throttle control

• Exhaust gas recirculation control (EGR)

• Turbo flap control

• Electric pumps, motor control and auxiliaries
