NCP308: Voltage Supervisor, Ultra Low Quiescent Current, Programmable Delay Time
The NCP308 series is one of the ON Semiconductor Supervisory circuit familiies. It is optimized to monitor system voltages from 0.405 V up to 5.5 V., asserting an active low open-drain /RESET output, together with Manual Reset (/MR) Input. The part comes with both fixed and internally adjustable versions
Features- Very low Quiescent Current 1.6 µV
- Fixed threshold voltage version for Standard Voltage Rails
- Adjustable threshold version available with low threshold (0.405 V min.)
- High Threshold Voltage Accuracy: 0.31% typical
- Wide Supply voltage range 1.6 to 5.5 V
- Manual Reset Input (/MR) - Open Drain /RESET Output (Push Pull available upo request)
- Flexible Delay Time Programmability (1.25 ms up to 10 s)
| Benefits- Saves battery and power supply power
- Saves external components, simple to design
- Flexible design
- Robust design
|
Applications- DSP or Microcontroller based applications
- PDA / Hand-Held Products
- Portable / Battery-Powered Products
- FPGA / ASIC Applications
| End Products- Notebook / Desktop Computers
