fault propagation within a group is desired, the
propagation bit needs to be checked in the GUI Fault
Management Window. The parameters can also be
programmed directly via the I 2 C bus by writing into
the PC3 register shown in Figure 41.
When propagation is enabled, the faulty POL pulls its
OK pin low. A low OK line initiates turn-off of other
POLs in the group.

In this case low OK line will signal DPM to pull other
OK lines low to initiate shutdown of other POLs as
programmed in the GUI Fault and Error Propagation
window. If an error is propagated, the DPM can also
generate commands to turn off a front end (a DC-DC
converter generating the intermediate bus voltage)
and trigger an optional crowbar protection to
accelerate removal of the IBV voltage.

Propagation of a fault (OCP, UVP, OTP, and TRP)
initiates regular turn-off of other POLs. The faulty
POL in this case performs either the regular or the
fast turn-off depending on a specific fault as
described in section 8.3.2.
Propagation of an error initiates fast turn-off of other
POLs. The faulty POL performs the fast turn-off and

In addition, the OK lines can be connected to the
DPM to facilitate propagation of faults and errors
between groups. One DPM can control up to 4
independent groups. To enable fault propagation
between groups, the respective bit needs to be
checked in the GUI Fault and Error Propagation
window shown in Figure 42.
turns on its low side switch.
Example of the fault propagation is shown in Figure
43 - Figure 44. In this three-output system (refer to
the block diagram in Figure 23), the POL powering
the output V3 (Ch 1 in the picture) encounters the
undervoltage fault after the turn-on. When the fault
propagation is not enabled, the POL turns off and
generates the UV fault signal. Because the UV fault
triggers the regular turn off, the POL meets its turn-
off delay and falling slew rate settings during the
turn-ff process as shown in Figure 43. Since the UV
fault is programmed to be non-latching, the POL will
attempt to restart every 130ms, repeating the
process described above until the condition causing
the undervoltage is removed.
If the fault propagation between groups is enabled,
the POL powering the output V3 pulls its OK line low
and the DPM propagates the signal to the POL
powering the output V1 that belongs to other group.
