The maximum operating temperature range for the IRLR3103 is -55°C to 150°C, but it's recommended to operate within -40°C to 125°C for optimal performance.
To ensure proper biasing, make sure to provide a stable voltage supply to the gate driver, and ensure the input voltage (VIN) is within the recommended range of 10V to 20V. Also, ensure the bootstrap capacitor (CB) is properly sized and placed close to the IC.
For optimal performance, it's recommended to follow a 2-layer or 4-layer PCB design with a solid ground plane, and keep the high-frequency components (such as the bootstrap capacitor and gate resistors) close to the IC. Also, ensure the PCB traces are short and wide to minimize inductance and resistance.
To protect the IRLR3103 from overvoltage and overcurrent conditions, consider adding overvoltage protection (OVP) and overcurrent protection (OCP) circuits to your design. You can also use a voltage regulator to regulate the input voltage and ensure it stays within the recommended range.
The recommended gate resistance value for the IRLR3103 is typically between 10Ω to 20Ω, but it may vary depending on the specific application and switching frequency. A higher gate resistance can help reduce EMI, but may also increase switching losses.
