LC75890W-2H Frequently Asked Questions (FAQs)

  • A good PCB layout for the LC75890W-2H should ensure that the power supply lines (VCC and GND) are separated from the signal lines, and that the decoupling capacitors are placed close to the IC. Additionally, the layout should minimize the loop area of the high-frequency signals to reduce EMI.
  • The value of RSET determines the internal oscillator frequency of the LC75890W-2H. A smaller RSET value results in a higher oscillator frequency, while a larger value results in a lower frequency. The recommended value for RSET is between 1 kΩ and 10 kΩ, depending on the specific application requirements.
  • The maximum allowable voltage on the output pins of the LC75890W-2H is VCC + 0.3 V. Exceeding this voltage may damage the IC.
  • To ensure proper reset, the RST pin should be pulled low for at least 10 μs during power-on. This can be achieved using an external reset circuit or by connecting the RST pin to the power supply line through a resistor and capacitor.
  • The recommended operating temperature range for the LC75890W-2H is -40°C to +85°C. Operating the IC outside this range may affect its performance and reliability.
