1.7 to 1.8V (low voltage mode setup)

[koji]

brownout reset = 1.7V Operating conditions VDD(Supply voltage,internal LDO setup) = 1.8V (by 1822 Product Specification)

In between 1.7V of 1.8V, or it would have been in any state. ( Specification NG? or There is a possibility of damage?)

Hi

The brownout is specified to put the chip in reset mode when supply voltage goes down to 1.7V. The chip should come out of reset again at 1.75V for low voltage mode configuration and at 1.80V for LDO mode configuration.

Thanks.

How should come out of reset again at 1.80V for LDO mode configuration. I should use Pin reset by Voltage Detector ic ?

When voltage drops below 1.7V, the chip goes into reset mode. When the supply voltage again exceeds 1.8V, the chip comes out of reset state automatically.

You're very kind. It was able to be understood.
