Device features Device Description Features MC33HB2000 The MC33HB2000 is a monolithic H-Bridge power IC, enhanced with SPI configurability, and diagnostic capabilities. • Advanced diagnostic reporting via a serial peripheral interface (SPI): charge pump 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 electromagnetic interference (EMI) and thermal performance optimization • Four selectable current limits via the SPI: 5.4 A, 7.0 A, 8.8 A, 10.7 A, covering a wide range of applications • Can be operated without the SPI with a 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 metal‑oxide‑semiconductor field‑effect transistors (MOSFETs): Maximum of 235 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 4.3.2 Modes of operation LOAD V PWR V PWR Load current ON OFF OFF ON OUT1 OUT2 Forward LOAD V PWR V PWR Load current ON OFF ON OFF OUT1 OUT2 Free-wheel high (Forward) LOAD V PWR V PWR Load current OFF ON ON OFF OUT1 OUT2 Reverse LOAD V PWR V PWR Load current OFF ON OFF ON OUT1 OUT2 Free-wheel low (Forward) PGND PGND PGND PGND PGND PGND PGND PGND Figure 2.
