The recommended operating voltage range for the SN55452BJG is 4.5V to 5.5V, with a typical voltage of 5V.
To ensure proper power-on and power-off, use a power-up and power-down sequence as described in the datasheet, and ensure that the input voltage rises and falls monotonically.
The maximum current rating for the SN55452BJG is 1A per channel, with a total current rating of 2A for both channels.
To handle thermal considerations, ensure good thermal conductivity between the device and the PCB, use thermal vias, and consider using a heat sink if necessary.
For optimal performance, use a 4-layer PCB with a solid ground plane, keep the device close to the power supply, and use short, wide traces for the output lines.
