Overview
The VN5770AKP-E is a quad smart power device from STMicroelectronics, housed in a standard SO-28 package. It integrates three monolithic chips: a double high-side switch and two low-side switches. The high-side switches utilize VIPower M0-5 technology, while the low-side switches are based on VIPower M0-3 OMNIFET II architecture. Designed for automotive applications, it complies with AEC-Q100 standards. The device supports a supply voltage range of 4.5V to 36V and can handle an output current of 8.5A per channel. It features a maximum load voltage of 41V and operates within a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrates double high-side and dual low-side switches for H-bridge or quad-switch configurations
- Provides proportional analog current sense feedback for load monitoring
- Includes built-in non-latching thermal shutdown with hysteresis for both high and low sides
- Features active inrush current management and linear current limitation
Applications
- Driving DC motors in bridge configuration
- Actuating automotive relays
- Controlling general low-voltage loads
- Power distribution in automotive body electronics
Procurement Notes
Verify component authenticity through authorized distributors as this part is marked as Not Recommended for New Designs (NRND). Confirm that the SO-28 tube packaging meets storage requirements due to moisture sensitivity classification. Ensure design reviews account for the end-of-life status when planning long-term production support.
Selection Notes
Select this component when a single IC solution is required for driving brushed DC motors or multiple independent loads. The integrated diagnostic capabilities, including thermal flags and current sensing, simplify system monitoring. Consider the specific VIPower technologies used for high-side versus low-side protection levels when designing fault-tolerant circuits.
Part Context
This device belongs to the VN5770 series of smart power switches. It is part of STMicroelectronics' VIPower family, which combines power MOSFETs with control and protection logic. The VN5770AKP-E specifically targets applications requiring robust automotive-grade reliability and compact integration of multiple switching channels.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the component is designated as NRND, alternative solutions should be evaluated based on pin compatibility and electrical specifications.
