RESET TIMER IC FOR MOBILE EQUIPMENTS |
|
| The R3200x Series are reset timer ICs with two input signals for mobile equipments which require long interval for reset sequence. The long interval prevents unexpected resets caused by accidental key operations. Internally, each of these ICs consist of a delay generator circuit and output driver transistors. The R3200x Series have two active-low input pins(SR0 and SR1) which generate reset signals after output delay time when both input pins are activated at the same time. The output delay time of the reset signals is user-selectable options of 7.5s or 11.25s by connecting DSR to either GND or VDD. While the reset signals are remaining active or being sent out, the ICs provide ultra-low supply current. The R3200x Series are available in DFN(PLP)2020-8B and DFN1216-8 (Under Development) packages |
