L99SM81V Programmable Stepper Motor Drivers

STMicroelectronics L99SM81V Programmable Stepper Motor Drivers are automotive-grade integrated drivers for two-phase bipolar stepper motors capable of current-controlled micro-stepping with programmable amplitude. These L99SM81V motor drivers feature programmable step and decay modes, integrated ADC, PWM frequency wobbling, 5V voltage regulator, integrated Serial Peripheral Interface (SPI), thermal warning, and shutdown. The L99SM81V programmable stepper motor drivers consist of an integrated ADC for coil voltage measurement and stall detection. These L99SM81V motor drivers regulate the current through the integrated PWM control with fully integrated current sensing.
