PRODUCTION DATA
Motors experience large currents at low speed, initial startup, and stalled rotor conditions. The large current at motor startup is sometimes called inrush current. The current regulation feature in the DRV8215 can help to limit these large currents. Additionally, DRV8215's soft-start feature can be used to limit the inrush current by ramping the PWM duty cycle during startup time. Alternatively, the microcontroller may limit the inrush current via a similar procedure.
