HB2002: SPI-Programmable H-Bridge Brushed DC Motor Driver

Overview

The HB2002 meets shifting demands for motor control applications in automotive and industrial spaces, delivering the efficient and robust performance necessary for tomorrow's safety-critical solutions.

Safety and Protection: H-Bridge motor driver designed using ISO 26262 processes to support ASIL C and D system qualifications.
Scalability: SPI-programmable current limits, slew rates, fault reporting, and control schemes enable the same IC to service various applications and motor sizes.
Thermal Management: Integrated power MOSFETs have temperature-dependent current limit foldback to reduce power and prevent excessive device heating.

Features

Advanced diagnostic and fault reporting, via SPI
Accuracy for real-time current feedback (5%)
Low RDS(on) integrated MOSFETs: 235 mΩ per device MAX (TJ = 150^°C)
Thermally-efficient QFN package: RΘJC < 1.0 ^°C/W
Wide operating range: 5 V to 28 V, 40 V transient
Eight slew rate options, selectable by SPI: 0.25 to > 16 V/µs
Four current limit options, selectable by SPI: 5.4/7.0/8.8/10.7 A
Configurable for full bridge or half-bridge mode
