AS5047P-ATSM from AMS, in a TSSOP-14. 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 | CSn | input | SPI chip select, active low. Digital input. If SPI is not used, a pull-up resistor on CSn is required. |
| 2 | CLK | input | SPI clock input. Digital input. If SPI is not used, a pull-down resistor on CLK is required. |
| 3 | MISO | output | SPI master data input, slave output. Digital output. Can be left open if SPI is not used. |
| 4 | MOSI | input | SPI master data output, slave input. Digital input. If SPI is not used, a pull-down resistor on MOSI is required. |
| 5 | TEST | input | Test pin. Must be connected to ground for normal operation. |
| 6 | B | output | Incremental encoder signal B (quadrature). Digital output. Can be left open if ABI is not used. |
| 7 | A | output | Incremental encoder signal A (quadrature). Digital output. Can be left open if ABI is not used. |
| 8 | W/PWM | output | Commutation signal W for BLDC UVW commutation, or PWM-encoded absolute-angle output. Digital output. Function is selectable via configuration register. |
| 9 | V | output | Commutation signal V for BLDC UVW commutation. Digital output. Can be left open if UVW is not used. |
| 10 | U | output | Commutation signal U for BLDC UVW commutation. Digital output. Can be left open if UVW is not used. |
| 11 | VDD | power_in | 5 V power supply input to on-chip regulator. Absolute max 7.0 V; operating range covers 5.0 V supply mode. Decoupling capacitor recommended. |
| 12 | VDD3V3 | power_out | 3.3 V on-chip low-dropout (LDO) regulator output. Requires an external 1 µF decoupling capacitor. In 3.3 V supply mode this pin is tied to the external supply. |
| 13 | GND | power_in | Device ground reference. |
| 14 | I/PWM | output | Incremental signal I (index pulse, one pulse per revolution) or PWM-encoded absolute-angle output. Digital output. Function is selectable via configuration. |
