MIC2775-29YM5-TR

MIC2775-29YM5-TR is a micropower low-voltage supervisor. Features include an under-voltage detector, a delay generator, a manual reset input, and both active-high and active-low reset outputs. The undervoltage detector compares VDD against a fixed threshold. Ten factory-programmed thresholds are available. The reset outputs are asserted for no less than 140ms at power-on and any time the input voltage drops below the reference voltage. It remains asserted for the timeout period after the input voltage subsequently rises back above the threshold boundary. A reset can be generated at any time by asserting the manual reset input, /MR. This reset output will remain active for at least 140ms after the release of /MR. The application includes monitoring processor core and input/output voltages, computer systems, PDAs/handheld PCs, embedded controllers, telecommunications systems, and power supplies.
