Power Supervisor ICs have programmable delay, watchdog timer.
Supplied in 4 x 4 mm, 20-pin QFN package, TPS386000 series supply voltage supervisors (SVSs) can monitor 4 power rails greater than 0.4 V with threshold accuracy of 0.25%. Independent programmable delay input, which can be set from 1.25 ms to 10 seconds for each supervisor channel, enables power supply sequencing. Operating with quiescent current of 12 -µA, ICs offer options for open-drain,...
