Overview
The VN770KPTR-E is a Quad Smart Power device from STMicroelectronics, classified under Motor / Motion / Ignition Controllers & Drivers. It functions as a brushed DC motor driver with an on-resistance of 225mOhm per channel and a continuous current capacity of 9A. The component operates within a VCC voltage range up to 36V. It holds AEC-Q100 qualification for automotive reliability. The device utilizes a surface-mount package available in Reel, Cut Tape, or MouseReel formats. It exhibits moisture sensitivity and is currently marked as End-of-Life by the manufacturer.
Feature Summary
- Quad smart power architecture providing four independent high-side outputs
- Integrated protection mechanisms including thermal shutdown and overcurrent limiting
- Automotive-grade qualification ensuring robustness in harsh environments
Applications
- Brushed DC motor control in automotive systems
- Ignition system drivers
- General motion control applications requiring high-side switching
Procurement Notes
Verify end-of-life status before integration. Confirm availability through authorized channels as distribution is restricted. Ensure design compatibility with existing thermal and electrical constraints given the discontinued lifecycle stage.
Selection Notes
Consider the 225mOhm on-resistance for power dissipation calculations. Evaluate the 9A current rating against peak load requirements. Check AEC-Q100 compliance if automotive standards are mandatory. Assess package options for manufacturing line compatibility.
Part Context
Part of the VN770KP-E series, designed for high-current switching applications. Competes with other quad smart power solutions offering similar current ratings and protection features in automotive and industrial sectors.
Replacement Considerations
No public confirmed substitute part numbers are available. Designers should evaluate alternative quad smart power devices with comparable 9A current and 36V voltage specifications.
