L6474PD Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 40V, but it's recommended to keep it below 35V for reliable operation.
  • The current sense resistors (R Sense) should be chosen based on the maximum current rating of the motor and the desired current sense threshold. A good starting point is to use a 0.1 ohm resistor for currents up to 2A and a 0.05 ohm resistor for currents up to 4A.
  • The ENN pin is an active-low enable input that allows the user to enable or disable the L6474PD. When ENN is low, the device is enabled, and when ENN is high, the device is disabled. This pin can be used to shut down the motor driver during idle periods to reduce power consumption.
  • The L6474PD can be configured for half-bridge or full-bridge operation by setting the BRG pin high or low, respectively. For half-bridge operation, BRG should be tied to VCC, and for full-bridge operation, BRG should be tied to GND.
  • The DIAG/FLAG pin is an open-drain output that indicates the occurrence of a fault condition, such as overcurrent, overtemperature, or undervoltage. The pin can be connected to a microcontroller or other logic circuit to detect and respond to fault conditions.
