The inhibit function can be used for a variety of applications, such as
The interrupt inputs should be controlled with open collector devices. The propagation delay between
the external device pulling the interrupt input low and the DPM pulling down OK lines and triggering the
turn-off process is approximately 10μs.
10.5.4.2
An interrupt that is programmed as a group reprogramming trigger always acts only on one group of
POL converters. Interrupt 0 acts on Group A, Interrupt 1 acts on Group B and so on. The assignment is
fixed and cannot be changed by the user.
When the interrupt is pulled low, the DPM will program the group of POL converters. Upon completion
of the programming, the DPM will turn-on the POL converters, if the Auto Turn-On is enabled. When
the interrupt input is released, the DPM will pull the appropriate OK line low. The POL converters in the
group will execute regular turn-off ramping their output voltages down according to the turn-off delay
and falling slew rate settings. In addition, the DPM will clear all bits in the POL Programming Status
registers.
The group reprogramming trigger is mostly used to support hot swap of boards and daughter cards that
do not have a DPM installed on them as shown in Figure 19.

Group Reprogramming Trigger
Hardware-based control of groups of POL converters and Auxiliary Devices
Delayed turn-on at power-up (Automatic Turn-On is enabled but the interrupts are held
low during power-up. Note that POL converters can be programmed even when an
interrupt is held low.)
