4.6 Voltage Comparators
There are six comparators that provide high speed comparator
operation for over voltage, over current, and various other
system event detections. For example, the comparators may be
used for zero crossing detection for an AC input line or
monitoring total DC bus current. Programmable internal analog
routing enables these comparators to monitor various analog
signals. These comparators include the following key features:
■
■
■
Six precision voltage comparators are available. The differential
positive and negative inputs of the comparators are routed from
the analog multiplexer and the output goes to the digital multi-
plexer. A programmable inverter is used to select the output
polarity. User selectable hysteresis can be enabled or disabled
to trade-off noise immunity versus comparator sensitivity.
4.7 Reference DACs
The reference DACs are used to generate set points for various
analog modules such as Hysteretic controllers and comparators.
The reference DACs include the following key features:
■
■
■
■
These DACs are available to provide programmable references
for the various analog and comparator functions and are
controlled by memory mapped registers.
DAC[0:7] are embedded in the hysteretic controllers and are
required to set the upper and lower thresholds for channel 0 to 3.
DAC [8:13] are connected to the Power Peripherals Analog
Multiplexer and provide programmable references to the
comparator bank. These are used to set trip points which enable
over voltage, over current, and other system event detection.

4.8 Built-in Switching Regulator
The switching regulator is used to power the low voltage (5V
portion of the PowerPSoC) from the input line. This regulator is
based upon a peak current control loop which can support up to
250 mA of output current. The current not being consumed by
PowerPSoC is used to power additional system peripherals. The
key features of the built-in switching regulator include:

4.9 Analog Multiplexer
The analog multiplexer is used to multiplex signals between the
power peripheral blocks. The CPU configures the Power Periph-
erals Analog Multiplexer connections using memory mapped
registers. The analog multiplexer includes the following key
features:
■
■
■
4.10 Digital Multiplexer
The digital multiplexer is used to multiplex signals between the
power peripheral blocks.The Power Peripherals Digital Multi-
plexer is a configurable switching matrix that connects the power
peripheral digital resources. This Power Peripheral Digital Multi-
plexer is independent of the main PSoC digital buses or global
interconnect of the PSoC core. The digital multiplexer includes
the following key features:
■
■
Ability to self power device from input line
Small filter component sizes
Fast response to transients
Connect signals to ensure needed flexibility
Ensure signal integrity for minimum signal corruption
