GPI1–GPI4 (MAX6874)/GPI1–GPI3 (MAX6875)
The GPI1–GPI4 programmable logic inputs control
power-supply sequencing (programmable outputs),
reset/interrupt signaling, and watchdog functions (see
the Configuring the Watchdog Timer (Registers
3Ch–3Dh) section). Configure GPI1–GPI4 for active-low
or active-high logic (Table 5). GPI1–GPI4 internally pull
down to GND through a 10A current sink.
MR
The manual reset (MR) input initiates a reset condition.
Register 40h determines the programmable outputs that
assert while MR is low (Table 6). All affected program-
mable outputs remain asserted (see the Programmable
Outputs section) for their PO_ timeout periods after MR
releases high. An internal 10A current source pulls MR
to DBP. Leave MR unconnected or connect to DBP if
unused. A programmable output cannot depend solely
on MR.
MARGIN
MARGIN allows system-level testing while power supplies
exceed the normal ranges. Drive MARGIN low to hold the
programmable outputs in their state while system-level
testing occurs. Leave MARGIN unconnected or connect
to DBP if unused. An internal 10A current source pulls
MARGIN to DBP. The state of each programmable output
does not change while MARGIN = GND. MARGIN over-
rides MR if both assert at the same time.
Programmable Outputs
The MAX6874 features eight programmable outputs
while the MAX6875 features five programmable outputs.
Program the open-drain outputs as active-high or
active-low. During power-up, the programmable outputs
pull to GND with an internal 10A current sink for 1V <
VABP < VUVLO. The programmable outputs remain in
their active states until their respective timeout periods
(PO_) expire and all of the programmed conditions are
met for each output. Any output programmed to depend
