19.1 Introduction
The Universal USS Power Supply (UUPS) is one of the submodules in the Ultrasonic Sensing Solution (USS) module. The USS module is designed for ADC-based ultrasonic sensing technology in various measurement applications. Figure 19-2 shows the block diagram of the USS module.
Figure 19-1 USS/USS_A Block Diagram The UUPS module consists of three blocks: the power sequencer (PSQ), the reference generator (BIAS_REF), and the USS LDO (see Figure 19-2).
- PSQ block: Controls the power-up and power-down sequences of the USS module.
- BIAS_REF block: Generates required reference voltages and currents for the SDHS, HSPLL, and USS LDO.
- USS_LDO block: Generates regulated 1.6 V, which is used by the USS submodules.
Figure 19-2 UUPS Block Diagram The signal names in Figure 19-2 are for information only to show how each block is connected inside the UUPS module. These signals are not under user control.
