Overview
The VN771KP-E is a Quad Smart Power device from STMicroelectronics, designed for automotive applications and compliant with AEC-Q100 standards. It integrates four independent high-side switches within a single SO-28 package, utilizing VIPower M0-3 technology. The component supports a supply voltage range of 5.5 V to 36 V and delivers a continuous output current of 9 A per channel. Each switch features a typical on-resistance of 95 mΩ. Integrated protection mechanisms include thermal shutdown, linear current limiting, overvoltage clamping, undervoltage lockout, and open-load detection with status flag feedback.
Feature Summary
- Integrates four independent high-side switches in a compact SO-28 package
- Provides comprehensive fault protection including thermal shutdown and short-circuit prevention
- Features diagnostic capabilities with open-load detection and status flag output
- Utilizes VIPower M0-3 technology for robust automotive-grade performance
Applications
- Automotive lighting systems
- Solenoid and relay driving
- Brushed DC motor control
- General low-voltage switching applications
Procurement Notes
Verify the obsolete status of this component before design finalization. Confirm availability through authorized distributors or secondary markets. Ensure replacement strategies are documented if production volumes require long-term supply assurance. Check specific ordering suffixes for packaging variations.
Selection Notes
Select this component when a quad high-side configuration is required for space-constrained designs. Consider the 95 mΩ on-resistance for power dissipation calculations at 9 A loads. Verify that the SO-28 package fits the PCB layout constraints. Ensure the control logic levels are compatible with the input requirements.
Part Context
This part belongs to the VN771 series of Quad Smart Power switches. It shares the same package and basic functionality as the VN770KP-E and VN772KP-E, differing primarily in the on-resistance values of the internal MOSFETs. The series is designed for high-reliability automotive environments requiring integrated diagnostics and protection.
Replacement Considerations
The VN770KP-E and VN772KP-E are direct pin-compatible alternatives within the same family. Selection depends on the specific on-resistance requirements (225 mΩ for VN770, 125 mΩ for VN772). Verify thermal performance differences due to resistance variations.
