1. Introduction

This user guide supports the evaluation kit for the Motion SPM®7 Series. It should be
used in conjunction with the Motion SPM®7 datasheets as well as Fairchild’s application
notes and technical support team. Please visit Fairchild’s website at

www.fairchildsemi.com.

1.1. Description

Fairchild’s Motion SPM®7 Series provides efficient motor control for energy restricted
small power inverter driven application when space is constrained, such as circulation
pump, compact fan.

Motion SPM®7 series integrates six fast-recovery MOSFETs (FRFET®) and one three­phase High Voltage ICs (HVIC). Motion SPM®7 series reduces board space by utilizing
an ultra-compact 12.9 mm x 12.9 mm package and by incorporating built-in HVIC that
provide single supply MOSFET gate driving capability. The Motion SPM®7 series offers
designers high reliability with integrated Under-Voltage Lockout (UVLO), Thermal
Sensing Function (VTS) and Over-Current Protection (OCP).
