MC33HB2000 10 A H-bridge, SPI programmable brushed DC motor driver Rev. 8 24 February 2020 Product data sheet 1 General description The MC33HB2000 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 MC33HB2000 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. 2 Simplified application diagram Figure 1.Simplified application diagram 3 Features and benefits 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/s to more than 16 V/s for EMI and thermal performance optimizationNXP Semiconductors MC33HB2000 10 A H-bridge, SPI programmable brushed DC motor driver Four selectable current limits via the SPI: 5.4/7.0/8.8/10.7 A covering a wide range of applications Three package sizes available in SOIC, PQFN and HVQFN to meet footprint and application requirement Can be operated without SPI with default slew rate of 2.0 V/s 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 R integrated MOSFETs: Maximum of 235 m (T = 150 C) for each DS(on) J 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 4 Applications Electronic throttle control Exhaust gas recirculation control (EGR) Turbo, swirl and whirl and waste flap control Electric pumps, motor control and auxiliaries 5 Ordering information This section describes the part numbers available to be purchased along with their differences.
