DESCRIPTION
The VNH3SP30 is a full bridge motor driver
intended for a wide range of automotive
applications. The device incorporates a dual
monolithic HSD and two Low-Side switches. The
HSD switch is designed using STMicroelectronics
VIPower M0-3 technology that allows to efficiently
integrate on the same die a true Power MOSFET
with an intelligent signal/protection circuitry. The
Low-Side switches are vertical MOSFETs
manufactured using STMicroelectronics
proprietary EHD (“STripFET™”) process.
