ADVANCE INFORMATION
The output stage's (EN1 to EN4), SEQ_DONE and PWRGD are of push-pull, active high type. The pull-up voltage for the push-pull outputs is externally provided by the user. PULL_UP1 (input) is the pull-up voltage domain for all ENx outputs (EN1 to EN4), while PULL_UP2 (input) is the pull-up voltage domain for the SEQ_DONE and PWRGD outputs.
Each output stage consists of a PMOS/NMOS (CMOS) pair. Each leg has an output resistance of typically 7Ω for VPULL_UPx > 3.3V. PULL_UP1 and PULL_UP2, have a voltage range of 1.6V to 7V, and can be independently biased or tied to the same voltage rail, however both most be biased. The output resistance of the PMOS leg has a PULL_UPx voltage dependency. The lower the PULL_UPx voltage, the higher the PMOS resistance.
When VIN < VPOR_IN and VPULL_UPx > VPOR_PULL_UPx (1.4V maximum) the output will be in a known pull-down state. At this condition the outputs have reduced sinking capabilities with VOL ≤ 320mV when the device is sinking 100μA of current into the outputs:
Once the input voltage range is withing the recommended input voltage range of 3V to 14 V, the output will have the full strength capabilities of ±10mA, per output.
