6.4.1 Operating Modes
The TMAG5170D-Q1 supports multiple operating modes for wide array of applications as explained in Figure 6-4. The device starts powering up after the VCC supply crosses the minimum threshold as specified in the Recommended Operating Conditions table. Any particular operating mode can be selected by setting the corresponding OPERATING_MODE register bits.
Figure 6-4 TMAG5170D-Q1
Power-Up SequenceTable 6-3 shows different power saving modes of the TMAG5170D-Q1.
Table 6-3 Comparing Operating
Modes
| OPERATING MODE | DEVICE FUNCTION | INITIALIZATION TIME TO START CONVERSION(1) | DATA CONVERSION |
|---|---|---|---|
| Active Conversion | Continuously measuring X, Y, Z axis, or temperature data | 10 μs | Supports continuous and trigger mode conversion |
| Standby Mode | Device is ready to accept SPI commands and start active conversion | 35 μs | Supports trigger mode conversion |
| Configuration Mode | SPI and user configuration registers active | tstand_by + 35 μs | Supports trigger mode conversion |
| Wake-up & Sleep Mode | Wakes up at a certain interval to measure the X, Y, Z axis, or temperature data | tstart_sleep + tstand_by + 35 μs | 1, 5, 10, 15, 20, 30, 100, 500, and 1000-ms intervals supported(1). |
| Sleep Mode | Device retains key configuration settings, and last measurement data | tstart_sleep + tstand_by + 35 μs | The microcontroller can use sleep mode to implement other power saving intervals not supported by wake-up and sleep mode. |
| Deep-sleep Mode | Device does not retain key configuration settings, and last measurement data | tstart_deep_sleep + tstand_by + 35 μs | No conversion start is supported during deep-sleep mode |
(1) The timing numbers are typical parameters. The values may vary
depending on the internal oscillator frequency.
