Overview
The VNH7100ASTR is a fully integrated H-bridge motor driver produced by STMicroelectronics. This device is designed for a wide range of automotive applications and features a dual monolithic high-side driver and two low-side switches. The switches are built using STMicroelectronics' proprietary VIPower® M0 technology, which integrates a true Power MOSFET with intelligent signal and protection circuitry. The VNH7100ASTR is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) package, ensuring superior manufacturability at the board level.
