A5973ADTR Frequently Asked Questions (FAQs)

  • The A5973ADTR can operate from -40°C to 150°C, but the recommended operating temperature range is -20°C to 125°C for optimal performance.
  • The A5973ADTR requires a single 5V supply voltage (VCC) and a separate ground pin (GND). Ensure that the power supply is stable and decoupled with a 10uF capacitor to prevent noise and oscillations.
  • The maximum current rating for the A5973ADTR is 1.5A per channel, but it's recommended to limit the current to 1A per channel for optimal performance and to prevent overheating.
  • The A5973ADTR can be configured for different motor types by adjusting the input pins (IN1, IN2, IN3, and IN4) and the enable pins (EN1 and EN2). Refer to the application note AN4872 for specific configuration examples.
  • The diagnostic pins (nFAULT and nOTW) provide fault detection and over-temperature warning signals. nFAULT indicates a fault condition, such as overcurrent or undervoltage, while nOTW indicates an over-temperature condition.
