SN75451BPSR datasheet by Texas Instruments

SN75451BPSR Frequently Asked Questions (FAQs)

• What is the maximum current that the SN75451BPSR can handle?
  The SN75451BPSR 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 SN75451BPSR from back-EMF when driving inductive loads?
  To protect the SN75451BPSR from back-EMF, you can add a freewheeling diode in parallel with the inductive load, or use a snubber circuit to absorb the back-EMF energy.
• What is the minimum input voltage required for the SN75451BPSR to operate?
  The minimum input voltage required for the SN75451BPSR to operate is 4.5V, but it's recommended to use a minimum of 5V for reliable operation.
• Can I use the SN75451BPSR to drive a relay?
  Yes, the SN75451BPSR can be used to drive a relay, but you need to ensure that the relay's coil voltage and current ratings are within the SN75451BPSR's specifications.
• How do I reduce the power dissipation of the SN75451BPSR?
  To reduce the power dissipation of the SN75451BPSR, you can use a heat sink, reduce the input voltage, or use a lower RDS(on) device.
