Product data sheet
General description
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.

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
