Tracking Protection
value of the difference exceeds 250mV, the tracking
Tracking protection is active only when the output
voltage is ramping up. The purpose of the protection
is to ensure that the voltage differential between
multiple rails being tracked does not exceed 250mV.
This protection eliminates the need for external
clamping diodes between different voltage rails
which are frequently recommended by ASIC
manufacturers.
When the tracking protection is enabled, the POL
continuously compares actual value of the output
voltage to its programmed value as defined by the
output voltage and its rising slew rate. If absolute
Vo

fault signal is generated, the POL turns off, and the
TR bit in the register ST is changed to 0. Both high
side and low side switches of the POL are turned off
instantly (fast turn-off).
The tracking protection can be disabled, if it
contradicts requirements of a particular system (for
example turning into high capacitive load where
rising slew rate is not important). It can be disabled
in the GUI Fault Management window or directly via
the I 2 C bus by writing into the PC1 register.

8.3.3 Errors
The group includes overvoltage protection and the
phase voltage error. The phase voltage error is not
available in ZY7015.
8.3.3.1 Overvoltage Protection
The overvoltage protection is active whenever the
output voltage of the POL exceeds the pre-bias
voltage (if any). If the output voltage exceeds the
overvoltage protection threshold, the overvoltage
error signal is generated, the POL turns off, and the
OV bit in the register ST is changed to 0. The high
side switch is turned off instantly, and simultaneously
the low side switch is turned on to ensure reliable
protection of sensitive loads. The low side switch
provides low impedance path to quickly dissipate
energy stored in the output filter and achieve
effective voltage limitation.
The OV threshold can be programmed from 110% to
130% of the output voltage setpoint, but not lower
than 1.0V.
8.3.4 Faults and Errors Propagation
The feature adds flexibility to the fault management
scheme by giving users control over propagation of
fault signals within and outside of the system. The
propagation means that a fault in one POL can be
programmed to turn off other POLs and devices in
the system, even if they are not directly affected by
the fault.
8.3.4.1 Grouping of POLs
Z-Series POLs can be arranged in several groups to
simplify fault management. A group of POLs is
defined as a number of POLs with interconnected
OK pins. A group can include from 1 to 32 POLs. If
