Overview
The VNH2SP30-E, produced by 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, utilizing STMicroelectronics' proprietary VIPower™ M0 technology for the high-side drivers and the EHD (STripFET™) process for the low-side switches. The components are assembled in a MultiPowerSO-30 package, which offers improved thermal performance and a symmetrical mechanical design suitable for harsh automotive environments.
