SN75452BDR datasheet by Texas Instruments

SN75452BDR Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the SN75452BDR?
  The SN75452BDR can operate from -40°C to 125°C, making it suitable for a wide range of applications.
• How do I ensure the SN75452BDR is properly powered?
  The SN75452BDR requires a dual power supply, with VCC1 ranging from 4.5V to 5.5V and VCC2 ranging from 4.5V to 18V. Ensure that the power supply is decoupled with capacitors to minimize noise and voltage drops.
• What is the maximum current rating for the SN75452BDR?
  The SN75452BDR can handle a maximum continuous current of 1A per channel, with a peak current rating of 2A per channel.
• How do I protect the SN75452BDR from back-EMF?
  Use a flyback diode (such as 1N4001-1N4007) in parallel with the relay coil to protect the SN75452BDR from back-EMF generated by the relay coil when it is turned off.
• Can I use the SN75452BDR to drive inductive loads?
  Yes, the SN75452BDR is designed to drive inductive loads such as relays, solenoids, and motors. However, ensure that the load is properly decoupled and that the SN75452BDR is properly powered to handle the inductive kickback.
