L6228N datasheet by STMicroelectronics

L6228N Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the L6228N?
  The L6228N can operate from -40°C to 150°C, making it suitable for high-reliability applications.
• How do I ensure the L6228N is properly powered?
  The L6228N requires a single 5V supply voltage (VCC) and a separate voltage supply (VREG) for the internal regulator. Ensure both supplies are properly decoupled and filtered to prevent noise and oscillations.
• What is the purpose of the EN (enable) pin?
  The EN pin is an active-high input that enables or disables the L6228N. When EN is high, the device is enabled, and when EN is low, the device is in shutdown mode, reducing power consumption.
• How do I configure the L6228N for half-bridge or full-bridge operation?
  The L6228N can be configured for half-bridge or full-bridge operation by connecting the appropriate pins. For half-bridge, connect the HB pin to VCC, and for full-bridge, connect the FB pin to VCC. Refer to the datasheet for specific pin connections.
• What is the maximum current rating for the L6228N?
  The L6228N can handle a maximum current of 2.5A per channel, making it suitable for high-current applications.
