Figure 1 shows a typical power-supply module for air bags. This application note presents a circuit using the MAX15006/MAX15007 linear regulators for reducing the quiescent current of automotive air-bag applications. In addition to offering an ultra-low quiescent current, these devices are...
This is because when a load switch turns off a load, the shutdown current is the contribution to the overall system power instead of the load current. For example, a load switch with a shutdown current of 200 nanoamps (nA) can turn off a Bluetooth® module and significantly reduce the...
Battery-Powered Products • Solid-State Drives • Set-Top Boxes • Industrial Control Systems 3 Description The TPS3890 is a precision voltage supervisor with low-quiescent current that monitors system voltages as low as 1.15 V, asserting an open-drain RESET signal when the SENSE voltage drop...

Once the ambient wind-speed exceeds 2 m/s, the wake TENG (W-TENG) and the self-waking module (SWM) can wake up the system within 0.96 s. At the same time, the signal processing module (SPM) starts to calculate the signal frequency from the measured TENG (M-TENG) to monitor ...
