Component

Description

A

 Device enable. Set slider to GREEN position to enable the driver.

B
  1. Firmware Version: EVM firmware version.
  2. VM voltage: supply voltage value.
  3. IMODE: current regulation mode (OFF: regulation disabled; ON: regulation always enabled; INRUSH: enabled only during inrush).
  4. SMODE: stall mode (LOW: latched nFAULT with outputs disabled; HIGH: nFAULT indication only with outputs remaining enabled; Hi-Z: NFAULT indication only with internal VREF=500mV).
  5. VREF: VREF value (range of 0V-3.3V).
  6. GAINSEL: current sense amplifier gain selection.
  7. PWM frequency: Switching PWM frequency selector. Default value is 25kHz and up to 100kHz.

Col
  1. Bridge Current: Output current (currently not functional. GUI to be updated)
  2. nFAULT: Fault status. Mirrors nFAULT LED (D11).
  3. CLEAR: click to clear fault or stall warning.
  4. STALL DETECTION: turns yellow when stall is detected. Cleared by pressing CLEAR button.
D IN1 and IN2 duty cycle control widget. Duty cycle ranges from 0-100 at the user selected PWM frequency. The duty cycle is adjustable by using the slider or writing to the input box.
E IN1 and IN2 ramp rate. The PWM slowly ramps up or down the duty cycle to avoid sudden speed changes. The ramp rate is adjustable from 0-25 with 0=no ramp and 25=slowest ramp rate.
