Description

Ground

Active-low reset output. RESETN remains low while VDD is

below the reset threshold and for tTP after VDD rises above

the reset threshold. RESETN is open-drain on the AS1906

and push-pull on the AS1904.

Active-high reset output. RESET remains high while VDD is

below the reset threshold and for tTP after VDD rises above

the reset threshold.
