Overview
The VNH3SP30-E is a full-bridge motor driver designed by STMicroelectronics for a wide range of automotive applications. This device integrates a dual monolithic high-side driver (HSD) and two low-side switches, utilizing STMicroelectronics' proprietary VIPower™ M0-3 technology and STripFET™ process. The HSD switch combines a true Power MOSFET with an intelligent signal/protection circuit on the same die, while the low-side switches are vertical MOSFETs. The component is packaged in a MultiPowerSO-30 package, which offers improved thermal performance and superior manufacturability due to its fully symmetrical mechanical design and exposed die pads.
