DS1236+5

DS1236+5 is a supervisor device from Maxim Integrated, designed to provide microprocessor and logic system reset functions. It also provides multiple supervisor functions to ensure that the microprocessor system functions correctly. This device has many applications in microprocessor-based systems since it offers high accuracy and reliable reset detection, as well as built-in safeguards against system errors. In this article, we will discuss the application field and working principle of the DS1236+5.

Application Field

The DS1236+5 can be used in different types of microcontrollers, such as 8-bit and 16-bit versions. It is especially suited for embedded systems that require a high level of accuracy and stability. It can be used to monitor the system power supply and protect the microcontroller from any sudden power fluctuations. Furthermore, it can also be used to monitor the temperature of the system and to provide an early warning of temperature rise.

In addition to embedded systems, the DS1236+5 can also be used in industrial applications where accuracy is critical. It offers high accuracy and dependability, along with protection circuits for system error levels. It can be used for reset detection, power supply monitoring, temperature monitoring and circuit status monitoring in industrial machines.

Working Principle

The DS1236+5 consists of two integrated circuits: one is the supervisor circuit and the other is the reset circuit. The supervisor circuit is responsible for monitoring the system parameters such as power supply, temperature, and circuit status. The reset circuit is connected to the active-low reset pin of the microcontroller. When any of the system parameters monitored by the supervisor circuit go beyond the predetermined levels, the reset circuit is activated and the reset pin is driven low. This causes the microcontroller to reset, thus ensuring system stability and accuracy.

The DS1236+5 features an integrated watchdog timer which is used to periodically monitor the system status. The watchdog timer monitors the reset pin and if it is held low for more than a predefined timeout period, it will reset the system. This ensures that the system recovers from any fault conditions and ensures that it can continue to run without any issues.

In addition to the watchdog timer, the DS1236+5 also features temperature supervision circuitry which monitors the temperature of the system. In the event of an over temperature condition, the reset circuit is activated and the microcontroller is reset. This prevents any system damage and ensures that the system continues to operate correctly.

Overall, the DS1236+5 is an excellent choice for embedded and industrial applications. It offers high accuracy and dependability, along with system error protection. The integrated watchdog timer and temperature supervision circuitry ensure that the system is protected from any unexpected errors or conditions. This makes the DS1236+5 a reliable and cost-effective solution for any microcontroller-based system.
