Part Number: TPS650861


Hi,
I would like to use GPO of TPS650861 in Push-Pull mode but the datasheet does not detail the electrical characteristics for this mode.

Could you clarify the following parameters, please :

Voltage : which rail feed theses GPO in push-pull mode : 3V3 or 1V8 ?

VOH ? VOL ? and current limitations ?

Thanks.

    Hi Samuel,

    For push-pull mode GPO1, GPO2, and GPO3 will be supplied by LDO3P3, so it will be 3.3V logic. GPO4 is not able to function in push-pull mode. The following are the expected characteristics for push-pull mode:

    VOL ≤ 0.4V and VOH ≥ 2.9V, when current ≤ 2mA

    Best regards,
