PRODUCTION DATA
Each VM terminal must be bypassed to GND using a low-ESR ceramic bypass capacitors with recommended values of 0.1 μF rated for VM. These capacitors should be placed as close to the VM pins as possible with a thick trace or ground plane connection to the device GND pin.
The VM pin must be bypassed to ground using a bulk capacitor rated for VM. This component may be an electrolytic.
A low-ESR ceramic capacitor must be placed in between the CP1 and CP2 pins. TI recommends a value of 0.1 μF rated for VM . 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. TI recommends a value of 0.47 μF rated for 16 V. Place this component as close to the pins as possible. In addition, place a 1 MΩ between VM and VCP.
Bypass V3P3OUT to ground with a ceramic capacitor rated 6.3 V. Place this bypassing capacitor as close to the pin as possible.
The current sense resistor should be placed as close as possible to the device pins to minimize trace inductance between the pin and resistor.
