R3200x SERIES Reset Timer IC for Mobile Equipments NO.EA-280-190531 OUTLINE The R3200x is a reset timer IC with two input signals for mobile equipment which require long interval for reset sequence. The long interval prevents unexpected resets caused by accidental key operations. Internally, the R3200x consists of a delay generator circuit and output driver transistors. The R3200x has two active-low input pins (SR0 and SR1) which generate reset signals after output delay time when both active-low input pins are activated at the same time. The R3200x has two versions that are different in output delay time settings and output release method. R3200x001x: Output delay time is selectable from 7.5 s or 11.25 s typ. by connecting the DSR pin to either GND or VDD. A reset signal can be released by making one of the active-low input pins high. R3200xxx2x, R3200L053B or R3200L064A: Output delay time is fixed. A reset signal will be released automatically after output release time. Or, by making one of the active-low input pins high, a reset signal can be released before output release time. The R3200x provides ultra-low supply current while a reset signal is remaining active or after being sent out. The R3200x is offered in a 8-pin DFN(PLP)2020-8B package or a 8-pin DFN1216-8 package. 1 R3200x NO.EA-280-190531 FEATURES Operating Voltage Range (Maximum Rating).................... 1.65 V to 5.5 V (6 V) Supply Current 1 (at standby) ...........................................
