... RESET pulse is issued, holding the output in the active state. When power rises above V approximately 250 ms to allow the system clock and other cir- cuits to stabilize. The reset output of FM1233B is of open-drain active low type. The FM1233B also can monitor a switch closure on its output, enabling it to recognize an external reset from a pushbutton switch or a µ ...

... REL Note 1 : Testing at production is done at 25°C only. Limits over temperature are guaranteed by design. Note 100pF 5V recommended to connect 100pF capacitor between the Reset pin and Ground pin if pushbutton reset is implemented. CC FM1233B Rev. D ESD Rating: -0.3V to +6.0V Human body model -0. 0.3V) ...

... RESET”) and stays there unless V falls below its minimum operating voltage, approx. 1V. At this point, the supervisor loses control, and its output may rise, only to again follow V down to the ground. CC FM1233B Rev. D Name GND GROUND RESET RESET remains LOW while V ...

... FM1233B does not sink very CC much current on the RESET pin. This is not a problem in most systems since common devices are not functional in this range desired for the FM1233B reset to be functional below this range, use a 100K pull-down resistor between RESET and V ...
