设计说明
The L9396B in PowerSO-20 package requires adequate PCB copper area for heat dissipation. The thermal resistance (junction-to-ambient) is [DATA_NEEDED: thermal resistance]. For high-current applications, use a multi-layer PCB with thermal vias under the exposed pad to improve heat transfer. Ensure the junction temperature stays below the maximum rating of 150C.
Place the input capacitor (e.g., 100nF) close to the VS pin to suppress voltage spikes. For inductive loads, place a flyback diode across the load to protect the device from back-EMF. Keep the control input trace short and away from high-current paths to avoid noise coupling.
Do not exceed the maximum operating voltage or output current ratings. Ensure the diagnostic output is properly pulled up to the microcontroller's logic level. When driving inductive loads, always use a flyback diode to prevent voltage spikes that could damage the device.
