PMIC, or Power Management Integrated Circuit, is a form of electronic device used to manage the energy supply to an electronic system. Supervisors are one type of PMIC, and primarily function as a circuit monitoring device, providing protection from short circuits, electrical overstresses and excessive temperature. As supervisors improve the efficiency and reliability of the power supply, their application field is constantly expanding. The MAX690TCSA+T supervisor is a combination reset/watchdog timer circuit specifically designed to monitor power supplies in digital systems. This article outlines the application fields and working principles of the MAX690TCSA+T.

Application Fields of the MAX690TCSA+T

The MAX690TCSA+T supervisor is designed for use in digital systems, wherever an accurate and reliable voltage monitoring is required. Typical applications include:

  • Computer systems and peripherals
  • Notebooks and tablets
  • Mobile phones
  • GPS receivers
  • Television sets and home audio equipment

The monitor consists of a voltage regulator, reset timer and watchdog timer. It is also capable of operating a power-on reset directly, as well as supplying a temperature/diode-connected opto-isolator output for remote system monitoring. The MAX690TCSA+T provides precise voltage monitoring, reset and reset timeout, accurate reset timing and precise watchdog timeout with excellent temperature stability.

Working Principles of the MAX690TCSA+T

The MAX690TCSA+T operates by continuously monitoring VCC and generating an internally latched reset if VCC falls below a preset voltage threshold. The reset is disabled until VCC rises above the threshold. A watchdog timer is also incorporated, providing a programmable reset timeout in the event of user program or processor lock-up. The watchdog timer has an internal oscillator with a timeout period adjustable from 8 milliseconds to 8.192 seconds.

The MAX690TCSA+T also contains an accurate voltage monitor. Adjusting the voltage monitor level is achieved by applying a voltage across an adjustable resistor. This, in turn, sets the voltage monitor level. The voltage regulator keeps VCC as close as possible to the predetermined voltage monitor level, regardless of power-supply noise or line transients. All monitor functions are totally independent, providing the maximum possible system safety and flexibility.

The MAX690TCSA+T is tailored to the application, providing desirable features and performance. Its drive capability can supply the power required to reset advanced CMOS systems, logic and multiplexers. In addition, very low power consumption makes the MAX690TCSA+T extremely efficient, greatly reducing power dissipation when compared to other comparable supervisors.

Conclusion

The MAX690TCSA+T supervisor has an extensive application field due to its multiple and precisely defined features. Its ability to operate a power-on reset, reset timeout and watchdog timer with fixed or adjustable timeout periods make it highly attractive for a variety of digital systems. Its capability to monitor supply voltage, temperature and other factors provide reliable system protection from electrical overstresses, short circuits and excessive temperature. The MAX690TCSA+T\'s low power consumption also provides excellent efficiency and reliability, which ensure the long-term viability of the system to which it is applied.
