AS5140H
Data Sheet - Detailed Description
Programming Daisy Chained Devices. In Daisy Chain mode, the Prog pin is connected directly to the DO pin of the subsequent device in 
the chain (see Figure 6). During programming (see Programming the AS5140H on page 19), a programming voltage of 7.5V must be applied to
pin Prog. This voltage level exceeds the limits for pin DO, so one of the following precautions must be made during programming:
 Open the connection 
 during programming, (or)
 Add a Schottky diode between DO and Prog (Anode = DO, Cathode = Prog)
Due to the parallel connection of CLK and CSn, all connected devices may be programmed simultaneously.
7.2 Incremental Outputs
Three different incremental output modes are possible with quadrature A/B being the default mode. Figure 8 shows the two-channel quadrature
as well as the step / direction incremental signal (LSB) and the direction bit in clockwise (CW) and counter-clockwise (CCW) direction.
7.2.1   Quadrature A/B Output (Quad A/B Mode)
The phase shift between channel A and B indicates the direction of the magnet movement. Channel A leads channel B at a clockwise rotation of
the magnet (top view) by 90 electrical degrees. Channel B leads channel A at a counter-clockwise rotation.
Figure 8. Incremental Output Modes
7.2.2   LSB Output (Step/Direction Mode)
Output LSB reflects the LSB (least significant bit) of the programmed incremental resolution (OTP Register Bit Div0, Div1). Output Dir provides
information about the rotational direction of the magnet, which may be placed above or below the device (1=clockwise; 0=counter clockwise; top
view). Dir is updated with every LSB change. In both modes (quad A/B, step/direction), the resolution and the index output are user
programmable. The index pulse indicates the zero position and is by default one angular step (1LSB) wide. However, it can be set to three LSBs
by programming the Index-bit of the OTP register accordingly (see Table 20).
