Presenting the STSPIN9 series

Designed for use in a variety of applications from domestic to industrial systems, STSPIN9 devices feature a wide input voltage range of 5 to 58 V range making it suitable for driving brushed DC motors and bipolar stepper motors.

Embedding system protection features including overcurrent, overtemperature and short-circuit protection, and low bus-voltage detection with under-voltage lockout (UVLO), these devices also integrate two operational amplifiers for current sensing that provide accuracy on design performance. STSPIN9 devices also support up to seven driving methods in parallel mode for higher design flexibility and scalability while streamlining the bill of materials.
