The datasheet provides general guidelines, but onsemi recommends following the application note AN5191 for detailed PCB layout and thermal management recommendations to ensure optimal performance and thermal dissipation.
For troubleshooting POR issues, check the power supply voltage, ensure correct pin connections, and verify the reset pin (RST_N) is properly connected to a pull-up resistor. If issues persist, consult onsemi's technical support or application notes for further guidance.
The maximum allowed voltage on I/O pins is VCC + 0.5V. To protect against overvoltage, use voltage clamping diodes or TVS (transient voltage suppression) diodes, and ensure the I/O pins are not exposed to voltages exceeding the recommended maximum.
Follow the recommended power-down sequence outlined in the datasheet, which typically involves disabling the clock, setting the device to a low-power state, and finally, removing the power supply voltage. Consult onsemi's application notes for specific guidance on power-down sequencing.
Handle the device with ESD-protective equipment, such as wrist straps and mats, and follow proper ESD handling procedures to prevent damage. The device has built-in ESD protection, but additional external protection measures may be necessary depending on the application.
