TPS65988: GPIO Level in TPS65988

Baghiya Lakshmi

Part Number: TPS65988

Hi,

I am working on TPS65988 based design.

I need to know whether the GPIOs in TPS65988 has an input level of 1.8V alone or can it accepts 3.3V GPIO input level also?

Hello,

The absolute maximum rating for the GPIO pins is 3.6 V, as shown in Table 6.1 of the datasheet. The recommended maximum GPIO voltage is to the LDO_3V3 rail. In addition, the high level input voltage GPIO_VH has a minimum of 1.8 V. I see no problem using 3.3 V for the GPIOs.

Thanks,

Mike Emanuel
