TLC393ID datasheet by Texas Instruments

TLC393ID Frequently Asked Questions (FAQs)

• What is the maximum current that the TLC393ID can handle?
  The TLC393ID can handle a maximum current of 1.5A per channel, making it suitable for a wide range of applications.
• How do I ensure that the TLC393ID is properly thermally managed?
  To ensure proper thermal management, it is recommended to provide a heat sink or a thermal pad to dissipate heat, especially in high-current applications. Additionally, ensure good airflow around the device and avoid blocking airflow to the heat sink.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled. This pin can be used to turn the device on and off, or to implement a shutdown function.
• How do I choose the right sense resistor value for my application?
  The sense resistor value depends on the current sensing requirements of your application. A smaller sense resistor value provides higher sensitivity, but may also increase the noise sensitivity. A larger sense resistor value provides lower sensitivity, but may also reduce the noise sensitivity. Typically, a sense resistor value between 0.1 ohm and 1 ohm is suitable for most applications.
• What is the purpose of the FLT pin, and how do I use it?
  The FLT (fault) pin is an open-drain output that indicates an overcurrent or overtemperature fault condition. When a fault occurs, the FLT pin is pulled low. This pin can be connected to a microcontroller or other logic circuit to detect and respond to fault conditions.
