FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
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 twelve 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. These sense circuits offer 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.
Temperature Sensor
The analog die includes an on chip temperature sensor.
This sensor offers a voltage which is proportional to the
actual mean chip junction temperature.
VSUP Prescaler
The VSUP prescaler offers a possibility to measure the
external supply voltage. The output of this voltage is VSUP /
RATIOVSUP.
EC Output
The EC output is directly connected to the multiplexer to
be able to read the actual voltage on the EC pin.
A0 and Multiplexer Control Register (A0MUCTL)
CSON — Current Source on/off
This read/write bit enables the current source for the A0 or
A0CST inputs. Reset clears CSON bit.
1 = Current Source enabled
0 = Current Source disabled
CSSEL[1:0] — Current Source Select Bits
These read/write bits select the current source values for
A0 or A0CST input. Reset clears CSSEL[1:0] bits.
CSA — H-Bridges Current Sense Amplification Select Bit
This read/write bit selects the current sense amplification
of the H-bridges HB1:HB4 current recopy. Reset clears the
CSA bit.
1 = low current sense amplification
0 = high current sense amplification
SS[3:0] — Analog Source Input Select Bits
These read/write bits selects the analog input source for
the ADOUT pin. Reset clears the SS[3:0] bits
