ST1PS02 - Impedance of logic inputs D0 D1 D2

Guille · ‎2025-09-03

Regarding ST1PS02. Which is current drained from logic inputs D0 D1 D2 when connected to Vin?
Is it safe to pullup them to VOUT, i.e., can it cause startup issues?
Thanks for the attention.

D0, D1 and D2 are high impedance logic inputs, so their input current is generally negligible and should be in the order of nanoamperes.

The same maximum voltage is specified for D0, D1 and D2 as for VIN. Since this is a buck regulator, you can also connect D0, D1 and D2 to VOUT.

Does this answer your questions?
