AS5045B-ASST from AMS, in a SSOP-16-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | MagINCn | output | Magnet field magnitude increase indicator; active-low open-drain output; indicates reduction in magnet-to-device distance. |
| 2 | MagDECn | output | Magnet field magnitude decrease indicator; active-low open-drain output; indicates increase in magnet-to-device distance. |
| 3 | A | output | Incremental quadrature output A; 1024 pulses per revolution. |
| 4 | B | output | Incremental quadrature output B; 1024 pulses per revolution. |
| 5 | NC | unconnected | No connect; must be left unconnected. |
| 6 | I | output | Index signal for quadrature output; zero position reference. |
| 7 | VSS | power_in | Ground; negative supply voltage. |
| 8 | PDIO | input | OTP programming input and daisy-chain data input; internal 74kΩ pull-down resistor; connect to VSS if programming disabled. |
| 9 | DO | tri_state | Synchronous serial interface data output; tri-state compatible. |
| 10 | CLK | input | Synchronous serial interface clock input; Schmitt-trigger input. |
| 11 | CSn | input | Chip select; active-low; Schmitt-trigger input; internal 50kΩ pull-up resistor. |
| 12 | PWM | output | Pulse width modulation output; duty cycle 1 to 4096 μs representing 0 to 359.91 degrees. |
| 13 | NC | unconnected | No connect; must be left unconnected. |
| 14 | NC | unconnected | No connect; must be left unconnected. |
| 15 | VDD3V3 | power_out | 3.3V LDO regulator output regulated from VDD5V; internal use only; do not load externally. |
| 16 | VDD5V | power_in | Positive supply voltage; operating range 3.0V to 5.5V. |
