Overview
The VN771K-E is a Quad Smart Power device designed for complete H-bridge configurations, manufactured by STMicroelectronics. It integrates three monolithic chips within a standard SO-28 package, comprising double high-side and two low-side switches. The component supports a maximum supply voltage of 36 V and a minimum of 5.5 V. It features an on-resistance of 95 mOhm and handles up to 9 A current. Qualified under AEC-Q100 standards, it serves as a brushed DC motor driver suitable for automotive applications.
Feature Summary
- Integrates double high-side and dual low-side switches in a single SO-28 package
- Qualified for automotive environments under AEC-Q100 standards
- Designed for complete H-bridge motor control configurations
Applications
- Brushed DC motor driving
- Automotive motion control systems
- Ignition controller circuits
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted or discontinued across major channels. Engineers must verify current stock status with authorized suppliers and prioritize alternative solutions due to the termination notification. Sourcing new units may be impossible through standard commercial channels.
Selection Notes
Select this part only if legacy compatibility with the SO-28 package and specific 9A/36V electrical ratings are required. Verify that the 95 mOhm on-resistance meets thermal management requirements for the target load. Ensure the design accommodates the EOL status by planning for long-term supply constraints or immediate migration to supported alternatives.
Part Context
The VN771K-E belongs to the VN771 series of smart power relays from STMicroelectronics. It is functionally related to the VN770KP-E, which shares similar packaging and automotive qualification but differs in internal resistance specifications. Both devices target integrated H-bridge applications in automotive electronics.
Replacement Considerations
Public documentation confirms the VN770KP-E as a related variant within the same family. Designers should evaluate the VN770KP-E for potential substitution, noting differences in on-resistance values while maintaining package and qualification compatibility.
