Power management integrated circuits (PMICs) are complex integrated circuits designed to ensure efficient energy management in electronics products. The DSM1836AS-10/T&R IC is a type of PMIC, which is a supervisor in particular. Supervisors prevent product system malfunctions and protect against overvoltage conditions, undervoltage conditions, and open circuits. This article explains the application field and working principle of the DSM1836AS-10/T&R supervisor.

Application Field of the DSM1836AS-10/T&R Supervisor

The DSM1836AS-10/T&R supervisor is specifically designed for use in industrial, building automation, automotive, and medical applications that require secure system monitoring and performance. The supervisor is a combination of several components in one IC package including overvoltage protection (OVP), undervoltage protection (UVP), and open circuit detection. It provides protection to your products against dangerous low and high voltages, which can destroy the product or its components.

The supervisor can also alert users on the status of the product. It has a detection range from 5.5 to 36V and offers accurate OVP supervision. It also has a resistance range for open-circuit detection from 0 to 10kΩ and offers adjustable UV and OV thresholds. The fast execution of detection and performance of the supervisor make it suitable for industrial, building automation, automotive, and medical applications.

Working Principle of the DSM1836AS-10/T&R Supervisor

When the DSM1836AS-10/T&R supervisor is powered, it performs a cycle of internal operations. In order to protect electronics against dangerous undervoltages, the supervisor detects shifts in the power supply voltage to determine whether it is too low. If it is, the supervisor will initiate a warning message. This message is sent to the user via an output pin which can be used to trigger the activation of a warning system or the reset of an external device, like a microcontroller.

In order to protect electronics against dangerous overvoltages, the supervisor monitors the supply voltage, and if it is too high, initiates a fault signal. The fault signal is sent to the user via an output pin, which can be used to activate a warning system, disable a control system, or other control operations. The supervisor also has a loose connection detection feature, which is used to detect any open circuits in the system.

In order to detect open circuits, the supervisor autonomously measures the resistance between the supply voltage and the monitored pin and if the measured resistance is outside of the specified resistance range for the open circuit, a fault signal is generated. The fault signal is sent to the users via an output pin, which can be used to warn the user of an open circuit or switch off a control system.

Conclusion

The DSM1836AS-10/T&R supervisor is a specialized PMIC designed to protect systems against overvoltages, undervoltages, and open circuits. It can provide accurate supervision of voltages and detect open circuits, and provides a warning or reset signal. The supervisor is especially suitable for industrial, building automation, automotive, and medical applications that require secure system monitoring and performance. Understanding its application field and working principle will help designers better utilize this powerful integrated circuit.
