MIC2755YMM-TR

Introducing MIC2755YMM-TR

The MIC275YMM-TR is a member of the MIC2750 family of voltage supervisors from Micrel. It opens the door to a range of applications, offering an efficient and versatile solution for products requiring system reset. The device can provide single-time-programmable thresholds up to 4.375 V and integrates various on-chip features including a POR (Power-on reset), two programmable reset outputs, two watchdog timers, a flexible reset monitoring voltage option, and a variety of selectable reset active polarity settings.

PMIC - Supervisor Applications:

The MIC275YMM-TR takes up an essential role in power management systems needing reliable reset control. This device can be used in applications including computers, servers, networking systems, data storage systems, wireless applications, audio and video systems, automotive systems, and many other consumer electronics products. It ensures that the system is properly restarted when it experiences a fault.

The MIC275YMM-TR is also widely used in industrial applications that have strict reliability requirements. It can provide the necessary reset protection for industrial controllers, system-on-chip (SoC) protection, industrial automation, instrumentation, and robotics applications.

Working Principle

The MIC275YMM-TR works by monitoring and comparing the threshold voltage of a pull-up voltage with the VCC supply voltage. When the voltage of the VCC supply falls below a certain threshold (programmable with a single-time-programmable resistor), a reset signal is generated. This reset signal can either be an active-low reset or an active-high reset depending on which polarity setting is selected and programmed.

The MIC275YMM-TR also features two programmable reset outputs, a manual reset input, and two independent watchdog timers. The two reset outputs can be used to reset two different systems, providing reliable and robust protection for a variety of applications. The manual reset input is used to issue a reset signal manually, and the two watchdog timers can be used to detect system or software lock-up and issue a reset signal.

Conclusion

The MIC275YMM-TR voltage supervisor from Micrel is a versatile, efficient, and reliable voltage supervisor. It is suitable for a wide range of consumer electronics and industrial applications, providing reliable and robust system reset protection. It can be used for monitoring and comparing the pull-up voltage and the VCC supply voltage, and it can issue a reset signal when the voltage of the VCC supply falls below a programmable threshold. It also comes with two programmable reset outputs, a manual reset input, and two independent watchdog timers.

The MIC275YMM-TR is the ideal choice for any system requiring reliable reset control. With its various features and capabilities, it can ensure your system is functioning properly and efficiently at all times.
