MIC708SM

MIC708SM Application Field and Working Principle

The MIC708SM is a part of the MSC supervisory series from Microchip Technology. It is a voltage supervisor designed to provide power-on reset (POR) and supervisor functions in a wide range of applications. It is designed to generate an intermittent reset signal to reset system circuitry after power has been applied. Additionally, it is designed to monitor the system voltage levels and provide an active reset signal if those levels are exceeded.

The MIC708SM is used in a variety of applications. It is most commonly used in embedded systems, such as single board computers, micro-controllers, processors, communications systems, automotive applications, industrial controls and portable electronics. Its highly integrated design, as well as its low standby power-consumption make it particularly suitable for battery-powered systems.

The MIC708SM is a voltage supervisor device which monitors the system power supply. It provides a reset signal if the monitored voltage falls outside of an adjustable window, and maintains the reset until the input voltage returns to within the window. The reset signal can be used to reset the system. The window is user adjustable and can be used to detect undervoltage, overvoltage, or both conditions.

The MIC708SM is a CMOS device with a typical operating voltage range of 2.0V to 7.0V. It is packaged in a 8- or 10-pin SOIC package, making it easy to use in space-constrained designs. The MIC708SM is also available in a slightly higher-rated 5-pin SOT-23 package.

The MIC708SM provides a number of features to ensure reliable system operation. It has an internal reference voltage that is used to monitor the voltage level. This is adjustable, and can be used to detect undervoltage, overvoltage, or both conditions. The MIC708SM also provides an open-drain active-low reset output signal. This signal is used to reset the system when the monitored voltage exceeds the threshold set by the user.

The MIC708SM also provides a programmable timeout feature which allows the user to configure the duration of the reset signal. This ensures that the system will reset even if the voltage does not remain outside the window for a long period of time. The device also provides an active-low manual reset input which can be used to trigger a reset without exceeding the voltage window.

Finally, the MIC708SM features an internal power-on reset (POR) circuit which provides an active-low signal to reset the system when power is first applied to the device. The POR signal is active for a minimum duration of 10ms and is used to ensure that the system is reset before operating. This is important to prevent any unforeseen behavior due to improper initial power on conditions.

In conclusion, the MIC708SM is a versatile voltage supervisor device suitable for a wide range of applications. Its highly integrated design and low standby power consumption make it perfect for battery-powered systems. The device offers adjustable monitoring of the voltage levels, active-low reset output for system resets, programmable timeout for reset duration, and an internal power-on reset circuit for initial reset. All of these features ensure reliable system operation.
