Overview
The VNH7070AYTR from STMicroelectronics is a fully integrated H-bridge motor driver designed for a wide range of automotive applications. This device incorporates a dual monolithic high-side driver and two low-side switches, all built using STMicroelectronics' proven VIPower® M0 technology. This technology allows for the efficient integration of true Power MOSFETs with intelligent signal and protection circuitry on the same die. The VNH7070AYTR is packaged in a PowerSSO-36 package, which includes three exposed islands for optimized thermal dissipation, making it suitable for the harsh automotive environment.
