The maximum operating temperature range for the TB67H302HG is -40°C to 125°C, but it's recommended to operate within -20°C to 85°C for optimal performance.
The TB67H302HG has a built-in thermal shutdown protection that turns off the output when the junction temperature exceeds 150°C. To handle this, ensure proper heat sinking, reduce the load current, or implement a thermal monitoring system to prevent overheating.
To minimize EMI, it's recommended to follow a 4-layer PCB layout with a solid ground plane, keep the high-frequency components away from the edges, and use a shielded layout for the motor connections. Additionally, use a common mode choke and a capacitor to filter the motor current.
Select external components based on the motor characteristics, operating frequency, and voltage. For example, choose a capacitor with a suitable voltage rating and capacitance value, and select a resistor with a suitable power rating and resistance value. Refer to the application notes and design guides for more information.
The maximum allowable voltage for the VCC pin of the TB67H302HG is 16V, but it's recommended to operate within 10V to 15V for optimal performance and to prevent damage to the internal voltage regulator.
