- SPI interface for advanced diagnostics （对比 MC33887)
设计说明
The L9960TR can dissipate significant power at high currents. For example, at 6A per channel with RDS(on) of 0.15 ohm, each channel dissipates 5.4W (I^2 * R). With two channels, total dissipation can reach 10.8W. The PowerSSO-36 package has a thermal resistance of 30 C/W (theta_JA) with proper PCB copper area. Ensure at least 2 square inches of copper on the exposed pad for adequate heat sinking. For continuous operation above 3A per channel, consider adding a heatsink or forced air cooling.
Place 100nF and 10uF ceramic capacitors close to the VS and VCC pins to decouple high-frequency noise. Use a star-ground topology to minimize ground bounce between the power stage and logic. Route the SPI lines (SCLK, SDI, SDO, CSN) away from high-current traces to prevent noise coupling. Keep the exposed pad connected to a large copper pour for thermal and electrical grounding.
Do not exceed the absolute maximum supply voltage of 40V, as this can damage the device. Ensure the logic supply (VCC) is within the specified range (typically 3.3V or 5V) to avoid improper SPI communication. When using PWM control, set the slew rate via SPI to match the motor's inductance to minimize EMI. Always enable the device (EN pin high) before sending PWM signals to avoid undefined states.
