SO and TSSOP HVQFN<br />
• Based on PCA9535 die with metal mask option to tie A2 high internally and bring<br />
out <strong>the</strong> POR circuit to <strong>the</strong> hardware reset pin.<br />
• Polling for input changes is not required since Interrupt output signals master.<br />
• Reset pin is needed for higher bus reliability to allow all devices to be reset should<br />
<strong>the</strong> bus hang up.<br />
