ROHM recommends a thermal pad size of at least 2.5mm x 2.5mm, with multiple vias to the ground plane to ensure efficient heat dissipation. A minimum of 3mm clearance around the device is also recommended to prevent thermal interference.
The QH8K26TR requires a stable input voltage (VIN) between 4.5V and 18V, with a recommended operating voltage of 12V. Ensure the input voltage is well-regulated and decoupled with a 10uF capacitor to prevent noise and oscillations.
The maximum power dissipation for the QH8K26TR is 2.5W. Exceeding this limit can cause the device to overheat, leading to reduced performance, reliability issues, or even failure.
The QH8K26TR is rated for operation up to 125°C (TJ). However, it's essential to ensure proper thermal management and derate the power dissipation accordingly to prevent overheating and ensure reliable operation.
Handle the QH8K26TR with ESD-safe materials and tools. Ensure the device is stored in an ESD-protected package, and ground yourself before handling the device. Use an ESD wrist strap or mat during assembly and testing.
