TLC7703QD datasheet by Texas Instruments

TLC7703QD Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC7703QD?
  The recommended operating voltage range for TLC7703QD is 2.7V to 5.5V. However, it can operate down to 2.3V with reduced performance.
• How do I ensure reliable operation of TLC7703QD in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to derate the output current and voltage according to the thermal derating curve provided in the datasheet. Additionally, ensure proper thermal management and heat sinking to keep the junction temperature below 150°C.
• What is the maximum output current that TLC7703QD can handle?
  The maximum output current that TLC7703QD can handle is 1.5A per channel. However, it is recommended to limit the output current to 1A per channel for reliable operation and to prevent overheating.
• How do I implement overcurrent protection using TLC7703QD?
  TLC7703QD has built-in overcurrent protection. To implement it, connect a sense resistor (Rs) between the output pin and ground. The device will limit the output current to 1.5A per channel when the voltage across Rs exceeds 0.5V.
• Can I use TLC7703QD as a high-side switch?
  Yes, TLC7703QD can be used as a high-side switch. However, it requires an external pull-up resistor to VCC to ensure proper operation. The pull-up resistor value should be chosen based on the output capacitance and the desired turn-on time.
