A5303SLETR-T Frequently Asked Questions (FAQ)

  • A good PCB layout for the A5303SLETR-T involves keeping the sense lines (VS, VM, and VG) as short as possible, using a ground plane, and minimizing the distance between the IC and the sense resistors. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.

  • The choice of sense resistors depends on the current range and the desired accuracy. A good starting point is to use resistors with a value between 0.01 ohms and 0.1 ohms. The datasheet provides a formula to calculate the sense resistor value based on the desired current range and the IC's internal resistance.

  • The A5303SLETR-T has an operating temperature range of -40°C to 150°C. However, the device's accuracy and reliability may degrade at extreme temperatures. It's recommended to operate the device within a temperature range of -20°C to 125°C for optimal performance.

  • To minimize EMI, use a shielded cable for the sense lines, keep the sense lines away from noise sources, and use a common-mode choke or ferrite bead on the sense lines. Additionally, ensure that the PCB layout is designed to minimize radiation and susceptibility to EMI.

  • The recommended power-up sequence is to apply the power supply voltage (VCC) first, followed by the input voltage (VIN). This ensures that the internal voltage regulator is powered up before the input voltage is applied.
