FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
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.
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.
Table 7. A0 Current Source Level Selection 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 Analog
Multiplexer Configuration Bits.
Hall-effect Sensor Input Pin H0
The H0 pin can be configured as general purpose input
(H0MS = 0) or as hall-effect sensor input (H0MS = 1) to be
able to read 3pin / 2pin hall sensors or switches.
