SET2
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 EN_R ) to enable voltage sequencing

SLEW
Slew-Rate Adjustment Input. Connect a capacitor from SLEW

monitoring mode) after MARGIN returns high. MARGIN is internally
pulled up to ABP through a 10μA current source.
