DS1836AS-5+T&R

PMIC (Power Management Integrated Circuit) - Supervisors are a type of integrated circuit used to detect and control faults in a power supply system. This type of IC facilitates the safe and efficient management of power for a wide range of applications including embedded systems. One example of PMIC - Supervisor is the Maxim Integrated DS1836AS-5+T&R. This IC monitors the power supply voltage and provides overtemperature protection for advances battery management system designs.

Application Field

The DS1836AS-5+T&R is ideal for applications in a broad range of industries. Rugged battery management systems, such as automotive rear monitoring systems, and mission critical applications, such as satellite systems and health monitoring systems, are just some of the potential usage fields enabled by the DS1836AS-5+T&R. Its ability to endure extreme temperatures, vibration, and shock ensures that the system remains safe and reliable in those environment.

Advances automated testing systems can utilize the power monitoring functions of the DS1836AS-5+T&R to detect inadequate power supply so that the system can be shut down and restarted with a more reliable power supply. This ensures that the testing system is always running in acceptable power conditions. Additionally, the device can be used to detect when the battery power is running low, alerting the user to switch to a more reliable battery.

Working Principle

The DS1836AS-5+T&R is a two-channel supervisor IC that monitors the power supply voltage and provides both overtemperature protection and short circuit protection. It includes a built-in comparator and a hysteresis comparator for improved circuit noise immunity. The overtemperature protection ensures that the system does not overheat due to faulty cooling systems or extended periods of use in hot environments. The short circuit protection prevents the system from being damaged in the event of an electrical surge.

The device works by monitoring the voltage of the power supply using a comparator integrated into the IC. If the voltage of the power supply exceeds the threshold set by the user, the IC will immediately shut down the power supply. The IC also monitors the temperature of the system using an internal temperature sensor. If the temperature surpasses the user-set threshold, the IC will also shut down the power supply to prevent further damage to the system.

In addition to monitoring the power supply voltage and the temperature, the DS1836AS-5+T&R provides advanced features such as soft-start and latching. Soft-start is used to reduce the inrush current at startup, which can prevent damaging the system from a large initial power surge. Latching prevents the system from being restarted until the power supply voltage and temperature are both within an acceptable range.

These features make the DS1836AS-5+T&R a robust and reliable solution for any application that requires power supply supervision. Its ability to detect overvoltage, overtemperature, and short circuit faults makes it an invaluable asset for mission-critical and industrial applications.
