Figure 3.ꢀVoltage regulation and monitoring
7.1.1 VCC, VREG, VREGA, undervoltage monitor
A circuit is incorporated to monitor the VCC supply voltage and the internally regulated
voltages VREG and VREGA. If any of the voltages fall below the specified undervoltage
thresholds in Table 101, SPI and I2C transactions are terminated. Once the supply
returns above the threshold, the device resumes responses.
7.2 Internal oscillator
The device includes a factory trimmed oscillator as specified in Table 102.
7.3 Pressure sensor signal path
7.3.1 Transducer
See Table 101 and Table 102 for transducer parameters.
