Product Introduction

Overview

The NCP308SN500T1G is a supervisory circuit IC from onsemi, designed to monitor system voltages and assert a RESET signal when the voltage drops below a specified threshold or when the Manual Reset (MR) input is driven low. This device is part of the NCP308 series, which offers both fixed and externally adjustable versions. The NCP308SN500T1G is specifically configured to monitor a nominal voltage of 5.0 V.

Q & A

  1. What is the primary function of the NCP308SN500T1G?

    The primary function is to monitor system voltages and assert a RESET signal when the voltage drops below the specified threshold or when the Manual Reset (MR) input is driven low.

  2. What is the supply voltage range for the NCP308SN500T1G?

    The supply voltage range is from 1.6 V to 5.5 V.

  3. What is the quiescent current of the NCP308SN500T1G?

    The quiescent current is typically 1.6 μA.

  4. What is the threshold voltage for the NCP308SN500T1G?

    The threshold voltage (VIT) is 4.65 V.

  5. How is the reset delay time programmed in the NCP308SN500T1G?

    The reset delay time can be programmed using the CT pin, either by connecting it to VDD, leaving it open, or using a capacitor to set a user-defined delay between 1.25 ms and 10 s.

  6. What are the package options for the NCP308SN500T1G?

    The device is available in a TSOP-6 package.

  7. Is the NCP308SN500T1G suitable for automotive applications?

    Yes, it is AEC-Q100 Qualified and PPAP Capable, making it suitable for automotive and other critical applications.

  8. What is the temperature range for the NCP308SN500T1G?

    The operating temperature range is from -40°C to +125°C.

  9. How does the Manual Reset (MR) input work?

    The MR input is internally tied to VDD by a 90 kΩ pull-up resistor and asserts the RESET signal when driven low.

  10. What is the RESET output type of the NCP308SN500T1G?

    The RESET output is an active low open-drain output, but a push-pull output is available upon request.
