PRODUCTION DATA
The VM pin should be bypassed to PGND using a low-ESR ceramic bypass capacitor with a recommended value of 0.01 μF rated for VM. This capacitor should be placed as close to the VM pin as possible with a thick trace or ground plane connection to the device PGND pin.
The VM pin must be bypassed to ground 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 0.022 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 0.22 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 0.47 μF rated for 6.3 V is recommended. Place this bypassing capacitor as close to the pin as possible..
