CAT853 Datasheet (ON Semiconductor) - 3-Pin Microprocessor Power Supply Supervisors

CAT853, 3-Pin Microprocessor Power Supply Supervisors

The CAT853, CAT863, CAT859, and CAT869 are supervisory circuits that monitor power supplies in digital systems.

These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 140 ms after the power supply level has risen abo
