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.
R3200x Series has two versions that are different in output delay time settings and output release method.
- - R3200x001x :
Output delay time selectable (7.5s or 11.25s) by connecting DSR pin to either GND or VDD. The reset signal will be canceled if either of the input pin becomes "H". Until either input pin becomes "H", the reset signal will be continually outputted.
- - R3200xxx2x or R3200L053B :
Output delay time is fixed. After the reset signal is being output, it will be released automatically or if either of the input pin becomes “H”, the reset signal will be canceled
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 packages.
