FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Figure 17. Analog Input and Multiplexer
A0 Current Source
The pin A0 provides a switchable current source, to be
able to read in switches, NTC, etc., without the need of an
additional supply line for the sensor. The overall enable of
this feature is done by setting the PSON bit in the System
Control register. In addition, the pin has to be selected with
the SS[3:0] bits. The current source can be enabled with the
CSON Bit and adjusted with the bits CSSEL[1:0].
With the CSSEL[1:0] bit’s, four different current values can
be selected (40, 120, 320 and 800A). This function is halted
during STOP and SLEEP mode operations.
The current source is derived from the VDD voltage, and is
constant up to an output voltage of ~4.75V.
To calibrate the current sources, an extra pin (A0CST) is
envisioned. On this pin, an accurate resistor can to be
connected. Switching the current sources to this resistor,
allows the user to measure the current and use the measured
value for calculating the current on A0.
Analog Multiplexer / ADOUT pin
The ADOUT pin is the analog output interface to the
Analog-to-digital converter of the MCU. To be able to have
different sources for the MCU with one single signal, an
analog multiplexer is integrated in the analog die. This
multiplexer has eleven different sources, which can be
selected with the SS[3:0] bits in the A0MUCTL register.
Half-bridge (HB1:HB4) Current Recopy
The multiplexer is connected to the four current sense
circuits on the low side FET of the half bridges. This sense
circuits offers a voltage proportional to the current through the
MOSFET. The resolution is depending on the CSA bit in the
A0 and Multiplexer control register (A0MUCTL).
High Side (HS1:HS3) Current Recopy
The multiplexer is connected to the three high side
switches. This sense circuit offers a voltage proportional to
the current through the transistor.
Analog Input A0 and A0CST
A0 and A0CST are directly connected to the analog
multiplexer. It offers the possibility to read analog values from
the periphery.
