NXP MC33HB2001FKR2

The MC33HB2001 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. The MC33HB2001 is able to control inductive loads with peak currents greater than 10 A. The nominal continuous average load current is 3.0 A. A current mirror output provides an analog feedback signal proportional to the load current. This part is designed to specifically address the ISO 26262 safety requirements. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified.

• 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
• Can be operated without SPI with default slew rate of 2.0 V/μs and a 7.0 A current limit threshold
• Highly accurate real-time current feedback through a current mirror output signal with less than 5.0 % error
• Drives inductive loads in a full H-bridge or Half-bridge configuration
• Overvoltage protection places the load in high-side recirculation (braking) mode with notification in H-bridge mode
• Wide operating range: 5.0 V to 28 V operation
• Low RDS(on) integrated MOSFETs: Maximum of 125 mΩ (TJ = 150 °C) for each MOSFET
• Internal protection for overtemperature, undervoltage, and short-circuit by signaling the error condition and disabling the outputs
• I/O pins can withstand up to 36 V
• AEC-Q100 grade 1 qualified

• Electronic throttle control
• Exhaust gas recirculation control (EGR)
• Turbo, swirl and whirl and waste flap control
• Electric pumps, motor control and auxiliaries
