PCA9535 I2C module lock-up issue

Hi,

We’ve been observing intermittent issues with the I2C GPIO extender IC, PCA9535. Have you observed/ know of any existing issues with this IC, wherein the I2C module “locks-up” and doesn’t come out of that state until a power reset? If there’s any application note/ design improvements about the same, please do share with us

Thanks and regards,

Srivatsa
