1 General Description

when the voltage goes below a predefined threshold. the supply voltage has risen above the threshold. AS1901, but has an active high reset. All devices operate down to a voltage of 1V. 2.2V and 3.08V in steps of approximately 100mV. time-out periods of 5/20/100/500ms. All devices are available in a 3-pin SOT23 package. Figure 1.
