Overview
The NSD7310-Q1HSPR is an automotive-grade single H-bridge brushed DC motor driver designed for applications requiring bidirectional control. It operates within a wide supply voltage range of 5V to 36V and delivers a peak current of 3.6A with a typical on-resistance of 520mΩ (HS+LS). The device features PWM control interface, integrated current chopping regulation, and comprehensive protection mechanisms including UVLO, OCP, and TSD. Qualified under AEC-Q100 standards, it utilizes an 8-pin HSOP package with exposed pad for efficient thermal management.
Feature Summary
- Bidirectional motor control via single H-bridge architecture
- Integrated current chopping regulation for peak current limiting
- Comprehensive fault protection including overcurrent and thermal shutdown
- Automotive qualification compliant with AEC-Q100 Grade 1
Applications
- Automotive VCU and OBC charger inlet locking systems
- Industrial printer motor drives
- Home appliance motor modules
- Robotics actuator control
Procurement Notes
Verify the specific suffix 'HSPR' against official Novosense documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required temperature grade and pinout configuration for your PCB layout. Cross-reference the datasheet revision date to guarantee compatibility with your design's electrical constraints and safety requirements.
Selection Notes
Select this component for designs requiring robust H-bridge control in space-constrained environments. The low on-resistance minimizes conduction losses, while the integrated current sensing capability reduces external BOM costs. Consider the operating temperature range and thermal dissipation capabilities when designing the heat sink or PCB copper area for continuous load conditions.
Part Context
This part belongs to the NSD731x series of brushed DC motor drivers from Novosense. The series includes industrial variants like NSD7310 and automotive-qualified versions such as NSD7312-Q1. These chips are engineered to provide reliable motor control solutions for both consumer electronics and stringent automotive applications, emphasizing efficiency and system-level protection.
Replacement Considerations
Direct substitutes include other NSD731x family members like NSD7312-Q1HSPR, provided pin compatibility and current ratings align with the design requirements. Verify that any replacement maintains the same H-bridge topology and protection feature set to ensure functional equivalence without redesigning the peripheral circuitry.
