8.7.1 Low Power Mode and Ultra Low Power Mode
Figure 25. Low Power Mode and Ultra Low Power Mode Connection
The AS5030 can be put in Low Power Mode or Ultra Low Power Mode by simple serial commands, using the regular connection for 2-wire or 3-
wire serial data transmission (see
The required serial command is SET PWR MODE (11
Note: After returning from Low Power mode or Ultra Low Power mode to normal operation (PSM = 0), if the Hysteresis is enabled (Hys=0), a
The two following cases describe the typical loop programmed in the software:
Hys = 0.

1. Wait for CPU interrupt or delay for next angle read (typ. <3ms in LP mode, typ>3ms in ULP mode)
2. Wake up (PSM = 0)
3. Set Reset (rst = 1)
4. Clear Reset (rst = 0)
5. Wait 1.5ms (Low Power Mode)
6. Check if Lock = 1 then read angle
7. Enable Low Power Mode or Ultra Low Power Mode (PSM=1)
8. Return to 1
ULP / LPn
general reset must be performed: set bit RST and then clear bit RST using command 15
