SN75462DR datasheet by Texas Instruments

SN75462DR Frequently Asked Questions (FAQs)

• What is the maximum current that the SN75462DR can handle?
  The SN75462DR can handle a maximum current of 1A per channel, with a total current limit of 2A for all channels combined.
• How do I protect the SN75462DR from back-EMF when driving inductive loads?
  To protect the SN75462DR from back-EMF, you can add a flyback diode (also known as a freewheeling diode) in parallel with the inductive load. This diode allows the energy stored in the inductor to dissipate safely when the switch is turned off.
• What is the minimum input voltage required for the SN75462DR to operate properly?
  The SN75462DR requires a minimum input voltage of 4.5V to operate properly. However, it's recommended to use a voltage of at least 5V to ensure reliable operation.
• Can I use the SN75462DR to drive a relay?
  Yes, the SN75462DR can be used to drive a relay. However, you need to ensure that the relay's coil current is within the SN75462DR's current rating, and that you provide a suitable flyback diode to protect the SN75462DR from back-EMF.
• How do I choose the right pull-up resistors for the SN75462DR's inputs?
  The pull-up resistors for the SN75462DR's inputs should be chosen based on the input signal's frequency and the desired rise time. A general rule of thumb is to use a pull-up resistor value between 1kΩ and 10kΩ.
