TPIC46L02DBR datasheet by Texas Instruments

TPIC46L02DBR Frequently Asked Questions (FAQs)

• What is the maximum current rating for each channel?
  The maximum current rating for each channel is 1.5A, but it's recommended to derate the current to 1A or less for reliable operation.
• How do I ensure proper thermal management for the device?
  Proper thermal management can be achieved by providing a heat sink or a thermal pad on the exposed pad of the device, and ensuring good airflow around the device. The thermal resistance of the device is 30°C/W.
• What is the minimum input voltage required for the device to function?
  The minimum input voltage required for the device to function is 4.5V, but it's recommended to operate the device at a minimum of 5V for reliable operation.
• Can I use the TPIC46L02DBR as a high-side switch?
  No, the TPIC46L02DBR is a low-side switch, and it's not suitable for high-side switching applications. It's designed to switch the ground connection of a load, not the positive supply voltage.
• How do I protect the device from inductive kickback?
  To protect the device from inductive kickback, a freewheeling diode (also known as a flyback diode) should be connected in parallel with the load. This diode allows the current to continue flowing when the switch is turned off, preventing voltage spikes that could damage the device.
