3. Continue operating for a given delay period, followed by
shutdown if the fault still exists.
4. Continue operating through the fault (this could result in
permanent damage to the power supply).
5. Initiate an immediate shutdown.
The default response from an overcurrent fault is an immediate
shutdown of the controller. The controller continuously checks for
the presence of the fault condition, and if the fault condition no
longer exists, the device is re-enabled.
Please refer to Application Note AN2033 for details on how to
select specific overcurrent fault response options via I 2 C/SMBus.
Thermal Overload Protection
The ZL9101M includes a thermal sensor that continuously
measures the internal temperature of the module and shuts
down the controller when the temperature exceeds the preset
limit. The default temperature limit is set to +125°C in the
factory, but the user may set the limit to a different value if
desired. See Application Note AN2033 for details. Note that
setting a higher thermal limit via the I 2 C/SMBus interface may
result in permanent damage to the controller. Once the module
has been disabled due to an internal temperature fault, the user
may select one of several fault response options as follows:
1. Initiate a shutdown and attempt to restart an infinite number
of times with a preset delay period between attempts.
FIGURE 13. OUTPUT RESPONSES TO PRE-BIAS VOLTAGES
If a pre-bias voltage higher than the target voltage exists after the
pre-configured delay period has expired, the target voltage is set
to match the existing pre-bias voltage, and both drivers are
enabled with a PWM duty cycle that would ideally create the
pre-bias voltage.
Once the pre-configured soft-start ramp period has expired, the
PG pin is asserted (assuming the pre-bias voltage is not higher
than the overvoltage limit). The PWM then adjusts its duty cycle
to match the original target voltage, and the output ramps down
to the preconfigured output voltage.
If a pre-bias voltage higher than the overvoltage limit exists, the
device does not initiate a turn-on sequence and declares an
overvoltage fault condition to exist. In this case, the device
responds based on the output overvoltage fault response method
that has been selected. See “Output Overvoltage Protection” on
page 10 for response options due to an overvoltage condition.
Note that pre-bias protection is not offered for current sharing
groups that also have tracking enabled. V DD must be tied to V IN
for proper prebias start-up in single module operation.
Output Overcurrent Protection
The ZL9101M can protect the power supply from damage if the
output is shorted to ground or if an overload condition is imposed
on the output. The following overcurrent protection response
options are available:
1. Initiate a shutdown and attempt to restart an infinite number
of times with a preset delay period between attempts.
2. Initiate a shutdown and attempt to restart a preset number of
times with a preset delay period between attempts.

2. Initiate a shutdown and attempt to restart a preset number of
times with a preset delay period between attempts.
3. Continue operating for a given delay period, followed by
shutdown if the fault still exists.
4. Continue operating through the fault (this could result in
permanent damage to the power supply).
5. Initiate an immediate shutdown.
If the user has configured the module to restart, the controller
waits the preset delay period (if configured to do so) and then
checks the module temperature. If the temperature has dropped
below a threshold that is approximately +15°C lower than the
selected temperature fault limit, the controller attempts to
re-start. If the temperature still exceeds the fault limit, the
controller waits the preset delay period and retries again.
The default response from a temperature fault is an immediate
shutdown of the module. The controller continuously checks for
the fault condition, and once the fault has cleared, the ZL9101M
is re-enabled.
Please refer to Application Note AN2033 for details on how to
select specific temperature fault response options via
I 2 C/SMBus.
I 2 C/SMBus Module Address Selection
Each module must have its own unique serial address to
distinguish between other devices on the bus. The module
address is set by connecting a resistor between the SA pin and
SGND. Table 2 lists the available module addresses.
