IC performs delayed system reset upon power-up

摘要

In most applications, the MR (manual-reset) pin usually connects to a switch to create a manual-reset signal to the supervisory chip. Subsequently, after a predetermined time-out-active period, it goes back to the high state in an active-low reset. A manual reset is a good feature for most applications; however, it requires human intervention to create the reset. In some applications, a manual reset could be a hassle because you must perform it each time the system powers up.
