7.3 Power Supply Recommendations

During the turn on and turn off switching transient, the peak source and sink current is provided by the VDD and VEE power supply. The large peak current is possible to drain the VDD and VEE voltage level and cause a voltage droop on the power supplies. To stabilize the power supply and ensure a reliable operation, a set of decoupling capacitors are recommended at the power supplies.Considering the device has ±5-A peak drive strength and can generate high dV/dt, a 1-µF bypass cap is recommended between VDD and COM, VEE and COM. A 0.1-µF decoupling cap is also recommended for VCC-GND and VDD-COM to filter out high frequency noise. The decoupling capacitors must be low ESR and ESL to avoid high frequency noise, and should be placed as close as possible to the VCC, VDD and VEE pins to prevent noise coupling from the system parasitics of PCB layout.

To forward bias the e-diode, it is recommended to use a single resistor tied directly to the anode pin, and connect the cathode pin directly to GND.
