Overview
The NSD7312-Q1HSPR is an automotive-grade single H-bridge driver for brushed DC motors, designed for applications such as EV charger inlet locking and industrial VCU systems. It operates within a 5V to 36V supply range and delivers up to 3.6A peak current with 1.5A continuous drive capability. The device features a typical 520mΩ resistance (HS+LS) and supports PWM control via current chopping. Integrated protections include UVLO, OCP, and TSD, with automatic fault recovery and nFAULT indication.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- Integrated current regulation using internal reference and ISEN pin voltage
- Comprehensive protection against undervoltage, overcurrent, and overtemperature conditions
- Automatic fault recovery mechanism upon removal of fault conditions
Applications
- Electric vehicle onboard charger inlet locking mechanisms
- Vehicle Control Unit (VCU) motor drives
- Industrial small machine actuation
- Appliance and robotics motor control
Procurement Notes
Verify the specific suffix 'HSPR' against official Novosense documentation to confirm tape-and-reel packaging specifications and exact marking codes. Ensure the component meets the required AEC-Q100 Grade 1 classification for the target automotive application environment. Cross-reference the HSOP8 package dimensions with the mechanical drawing to ensure PCB footprint compatibility.
Selection Notes
Select this component for brushed DC motor applications requiring high reliability in automotive environments. The integrated current chopping reduces system power requirements and bulk capacitance needs during startup or stall. The exposed pad design aids thermal dissipation, while the low quiescent current in sleep mode optimizes energy efficiency for battery-supplied systems.
Part Context
This part belongs to the NSD731x series of brushed DC motor drivers from Novosense. The series includes variants like NSD7310 and NSD7312, with the '-Q1' suffix denoting automotive qualification. The NSD7312 specifically offers higher peak current compared to lower-current variants, making it suitable for demanding actuator loads in electric vehicles and industrial machinery.
Replacement Considerations
NSD7312: Industrial grade equivalent without automotive certification.
FAQ
How does the device handle fault conditions?
The device provides automatic fault recovery when the fault condition is removed. It also features a dedicated n_FAULT pin to indicate fault status to the microcontroller.
What is the function of the ISEN pin?
The ISEN pin allows for current chopping regulation based on the internal reference and the voltage on the pin, which is proportional to the current flowing through the motor.
