Figure 5: AS5045 Adapter PCB schematic
For normal operation, the only required external components are the buffer cap at VDD3V3 (C4) and the pull-down
resistor for CSn (R7; 0
Ω
….4k7).
The PCB operates at several power supply levels:
Power Supply options:
Supply
voltage
apply at ext. voltage regulator
IC2 or IC3
digital I/O
level
remark
3,0….3,6V VDD5V and VDD3V3 not required *) 3.0….3.6V short VDD5V and VDD3V3
4,5….5,5V VDD5V not required *) 4.5….5.5V
7,5…20V ext. voltage regulator
(pin 1, J2)
3.3V type, e.g. LE33C
(ST Micro)
3.3V short VDD5V and VDD3V3
7,5…20V ext. voltage regulator
(pin 1, J2)
5.0V type
e.g. 75L05
5.0V PCB delivery status
*) if already installed, external voltage regulator can be left installed.
