TPIC6C595PWRG4 datasheet by Texas Instruments

TPIC6C595PWRG4 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the clock input?
  The maximum frequency of the clock input is 30 MHz, but it's recommended to operate at 20 MHz or less for reliable operation.
• How do I handle the power-up sequence for the TPIC6C595PWRG4?
  It's recommended to power up the VCC pin first, followed by the VCCIO pin. This ensures that the internal logic is powered up before the output stages.
• What is the maximum current rating for each output pin?
  The maximum current rating for each output pin is 150 mA. However, the total current drawn from the device should not exceed 1.5 A.
• How do I ensure that the output pins are not damaged due to back-EMF?
  It's recommended to use a flyback diode or a freewheeling diode across the output pins to protect against back-EMF. This is especially important when driving inductive loads.
• Can I use the TPIC6C595PWRG4 to drive LEDs?
  Yes, the TPIC6C595PWRG4 can be used to drive LEDs. However, it's recommended to use a series resistor to limit the current to the LED and prevent overheating.
