Design Notes

The L9960-TR can dissipate significant power when driving high currents. For example, at 6A per bridge with a 0.3 ohm RDS(on), each MOSFET dissipates about 10.8W (P = I^2 * R). The PowerSSO-36 package has an exposed pad that must be soldered to a large copper area on the PCB to achieve the specified thermal resistance. Use multiple vias to connect the pad to inner and bottom layers for effective heat spreading. Ensure the junction temperature stays below 150C by providing adequate cooling, especially in high-ambient-temperature automotive environments.

Place 100nF ceramic capacitors close to each VS pin and a bulk electrolytic capacitor (e.g., 100uF) near the supply input to handle current transients during motor switching. The SPI lines should be kept short and routed away from high-current traces to avoid noise coupling. Use a ground plane to minimize inductance and provide a low-impedance return path. The exposed pad should be connected to the ground plane with multiple vias to enhance thermal and electrical performance.

Do not exceed the absolute maximum supply voltage of 28V, as this can damage the device. Ensure the SPI interface is properly initialized before enabling the outputs to avoid unintended motor movement. The enable pin (EN) must be pulled high to activate the outputs; leaving it floating can cause unpredictable behavior. Also, verify that the motor's back-EMF does not exceed the supply voltage, as this could trigger overvoltage protection or damage the device. Use freewheeling diodes or the integrated body diodes to handle inductive kickback.
