TPIC6B595DWR datasheet by Texas Instruments

TPIC6B595DWR 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 10 MHz or less for reliable operation.
• How do I handle the power-up sequence for the TPIC6B595DWR?
  It's recommended to power up the VCC pin first, followed by the VCCIO pin. This ensures that the internal voltage regulator is powered up correctly.
• 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 TPIC6B595DWR to drive LEDs directly?
  Yes, the TPIC6B595DWR can be used to drive LEDs directly. However, it's recommended to use a current-limiting resistor in series with the LED to prevent overcurrent.
