Manufacturer: STMicroelectronics

Overview: powerSTEP01 System-in-package integrating microstepping controller and 10 A power MOSFETs Datasheet - production data Applications  High power bipolar stepper motor – Stage lighting – Surveillance systems – Textile and.

General Description

The powerSTEP01 is a system-in-package integrating 8 N-channel 16 mΩ MOSFETs for stepper applications up to 85 V with an SPI programmable controller, providing a full digital control of the motion through a speed profile generation and positioning calculations.

It integrates a dual low RDS(on) full-bridge with embedded non-dissipative overcurrent protection.

The device can operate with both voltage mode driving and advanced current control fitting different application needs.
