On the ISL6131 these inputs provide for a programmable UV threshold referenced to an internal 0.633V. The
related STATUS output will assert once the related input > internal reference voltage.
On the ISL6132, these inputs provide for a programmable UV and OV threshold referenced to an internal 0.633V
reference. In the ‘AB’ pair VMON_A is the UV input and VMON_B is the OV input. In the ‘CD’ pair VMON_C is
the UV input and VMON_D is the OV input.
These inputs have a 30μs glitch filter to prevent PGOOD reset due to a transient.

PGOOD
On the ISL6131, PGOOD is the boolean AND function of all four STATUS outputs.
On the ISL6132, PGOOD is for the AB pair and signals high when the monitored voltage is within the specified
window and the A and B STATUS output states are correct.
This is an open drain output and is to be pulled high to the appropriate level with an external resistor to a V_DD
maximum level.

STATUS_D
PGOOD2 is for the CD pair and signals high when the monitored voltage is within the specified window and when
the C and D STATUS output states are correct.
This is an open drain output and is to be pulled high to the appropriate level with an external resistor to a V_DD
maximum level.
On the ISL6131 each STATUS provides a high signal through pull-up resistors about 160ms after its related
VMON has continuously been > Vuv_vth. This delay is for stabilization of monitored voltages. STATUS will de-
assert and pull low upon VMON not being satisfied for about 30μs.
On the ISL6132 the STATUS outputs indicate compliance with a high output state for each pair of monitors.
