5.2 Pin Description
Table 1 shows the description of each pin of the standard SSOP16 package (Shrink Small Outline Package, 16
leads, body size: 5.3mm x 6.2mmm; see Figure 2 ).
Pins 7, 15 and 16 supply pins, pins 3, 4, 5, 6, 13 and 14 are for internal use and must not be connected.
Pins 1 and 2 MagINCn and MagDECn are the magnetic field change indicators (magnetic field strength increase or
decrease through variation of the distance between the magnet and the device). These outputs can be used to
detect the valid magnetic field range. Furthermore those indicators can also be used for contact-less push-button
functionality.
Pin 6 Mode allows switching between filtered (slow) and unfiltered (fast mode). This pin must be tied to VSS or
VDD5V, and must not be switched after power up. See chapter 8 Mode Input Pin.
Pin 8 Prog is used to program the zero-position into the OTP (see chapter 11.1 Zero Position Programming).
This pin is also used as digital input to shift serial data through the device in Daisy Chain configuration,
(see chapter 8.2 Daisy Chain Mode).
Pin 11 Chip Select (CSn; active low) selects a device within a network of AS5045 encoders and initiates serial data
transfer. A logic high at CSn puts the data output pin (DO) to tri-state and terminates serial data transfer. This pin is
also used for alignment mode ( Figure 14 ) and programming mode ( Figure 10 ).
Pin 12 PWM allows a single wire output of the 10-bit absolute position value. The value is encoded into a pulse width
modulated signal with 1μs pulse width per step (1μs to 4096μs over a full turn). By using an external low pass filter,
the digital PWM signal is converted into an analog voltage, making a direct replacement of potentiometers possible.
