ABP
No Connection. Not internally connected.
Internal Supply Bypass Input. Bypass ABP with a 1µF capacitor to
GND. ABP maintains the device supply voltage during rapid power-
down conditions.
Externally Adjusted IN_ Undervoltage Lockout Threshold. Connect
SET_ to an external resistor-divider network to set the desired
undervoltage threshold for each IN_ supply (see the Typical
Application Circuit). All SET_ inputs must be above the internal
SET_ threshold (0.5V) to enable sequencing functionality.
Logic-Enable Input or Undervoltage Lockout Monitor Input. EN/UV
must be high (EN/UV > V
power-up operation. OUT_ begins tracking down when EN/UV <
V
the external UVLO threshold.
Ground
Sequence Delay Select Input. Connect a capacitor from DELAY
to GND to select the desired delay period before sequencing is
enabled (after all SET_ inputs and EN/UV are above their respective
thresholds) or between supply sequences. Leave DELAY
unconnected for the default 200µs delay period.
Slew-Rate Adjustment Input. Connect a capacitor from SLEW
to GND to select the desired OUT_ slew rate.
PG/RST Timeout Period Adjust Input. PG/RST asserts high after the
timeout period when all OUT_ exceed their IN_ referenced
threshold. Connect a capacitor from TIMEOUT to GND to set the
desired timeout period. Leave TIMEOUT unconnected for the
default 200µs delay period.
Margin Input, Active-Low. Drive MARGIN low to enable margin
mode (see the Margin Input ( MARGIN ) (MAX6880/MAX6882)
section). The MARGIN functionality is disabled (returns to normal
monitoring mode) after MARGIN returns high. MARGIN is internally
pulled up to ABP through a 10µA current source.
