Due to the increasing popularity of battery-powered consumer electronics and the demand for lower power consumption and enhanced charging efficiency, power sensing or monitoring has become increasingly important in many consumer electronic products. Of course, in battery-powered systems, the low power consumption of the power monitoring subsystem is a prerequisite. For example, in battery packs or portable chargers used in consumer electronics, users must know the remaining battery capacity to initiate the charging cycle before the battery charge is depleted. The compact, cost-effective, and ultra-low-power MSPM0L134x MCU with an integrated TIA can detect the current during battery discharge and track the remaining capacity. The MSPM0L134x MCU is also at the core of various energy-efficient green power applications. For instance, different types of printers can utilize these microcontrollers to monitor power usage and control when to switch the printer to standby mode to reduce system power consumption. Pressing a button or an automatic signal from the microcontroller can wake the printer to full power mode when needed.

Figure 3-3 shows examples of some of the applications that can benefit from the MSPM0L134x MCUs.
