MC33HB2001

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

Rev. 6.0 — 3 May 2016

Data sheet: Advance information

1 General description

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.

The 33HB2001 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.

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/μs to more than 16 V/μs for EMI and

thermal performance optimization
