Product Introduction

Overview

The NCP3230MNTXG is part of the NCP302 and NCP303 series of ultra-low current voltage detectors produced by onsemi. These devices are designed for use as reset controllers in portable microprocessor-based systems, where extended battery life is crucial. The NCP3230MNTXG features a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator, which prevents erratic system reset operations.

  2. What is the quiescent current of the NCP3230MNTXG?

    The quiescent current of the NCP3230MNTXG is typically 0.5 μA.

  3. What is the operating voltage range of the NCP3230MNTXG?

    The operating voltage range of the NCP3230MNTXG is from 0.8 V to 10 V.

  4. Can the time delay be programmed externally?
  5. What types of reset outputs are available?

    The NCP3230MNTXG offers both active low and active high reset output configurations.

  6. What is the temperature range for the NCP3230MNTXG?

    The NCP3230MNTXG is specified to operate over the -40°C to +125°C temperature range.

  7. Is the NCP3230MNTXG suitable for automotive applications?
  8. What is the detector threshold hysteresis?

    The detector threshold hysteresis is between 0.120 V and 0.280 V, depending on the voltage option.

  9. How does the NCP3230MNTXG prevent erratic system reset operations?

    The NCP3230MNTXG prevents erratic system reset operations through its combination of a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator.

  10. What is the maximum output current of the NCP3230MNTXG?

    The maximum output current for active low devices is up to 2.0 mA, and for active high devices, it is up to 11 mA.
