Layout Guidelines

  • The VM pins should be bypassed to PGND pins using low-ESR ceramic bypass capacitors with a recommended value of 0.01 µF rated for VM. The capacitors should be placed as close to the VM pins as possible with a thick trace or ground plane connection to the device PGND pins.

  • The VM pins should be bypassed to PGND using a bulk capacitor rated for VM. This component can be an electrolytic capacitor.

  • A low-ESR ceramic capacitor must be placed in between the CPL and CPH pins. A value of 0.1 µF rated for VM is recommended. Place this component as close to the pins as possible.

  • A low-ESR ceramic capacitor must be placed in between the VM and VCP pins. A value of 1 µF rated for 16 V is recommended. Place this component as close to the pins as possible.

  • Bypass the DVDD pin to ground with a low-ESR ceramic capacitor. A value of 1 µF rated for 6.3 V is recommended. Place this bypassing capacitor as close to the pin as possible.

  • Bypass the VCC pin to ground with a low-ESR ceramic capacitor. A value of 0.1 µF rated for 6.3 V is recommended. Place this bypassing capacitor as close to the pin as possible.

  • In general, inductance between the power supply pins and decoupling capacitors must be avoided.

  • The thermal PAD of the DDW package must be connected to system ground.

    • It is recommended to use a big unbroken single ground plane for the whole system / board. The ground plane can be made at bottom PCB layer.

    • In order to minimize the impedance and inductance, the traces from ground pins should be as short and wide as possible, before connecting to bottom layer ground plane through vias.

    • Multiple vias are suggested to reduce the impedance.

    • Try to clear the space around the device as much as possible especially at bottom PCB layer to improve the heat spreading.

    • Single or multiple internal ground planes connected to the thermal PAD will also help spreading the heat and reduce the thermal resistance.
