... STM1001 1 Description The STM1001 microprocessor reset circuit is a low-power supervisory device used to monitor power supplies. It performs a single function: asserting a reset signal whenever the V supply voltage drops below a preset value and keeping it asserted until V CC above the preset threshold for a minimum period of time (t Figure 1 ...
