Power management integrated circuits, or PMICs for short, are essential components for modern applications like those found in industry, medical, automotive, and consumer electronics. PMICs serve a multifunctional role in the power supply chain, providing integrated solutions designed to guarantee the correct power sequencing, monitoring, and control necessary for reliable device operation. Among the most popular of PMICs are supervisors, also known as system batteries, which serve as a failsafe to protect systems from unwanted power glitches, faults, and other errors. DS1236S-10N+T&R is a member of the DS1236 family of supervisors, and this article will discuss its application field and how it works.

The DS1236S-10N+T&R is a universal supervisor powered by a 3.3V core voltage, and is optimized to provide overvoltage, undervoltage, 0V input, and loss-of-clock protection for applications in industrial, all-in-one (AIO), medical, and automotive equipment. This supervisor is also suitable for new designs as well as replacements, and can guarantee stable operation in all operating temperature ranges. The DS1236S-10N+T&R supports both TTL and CMOS logic, and is available in a QFN package or with an 8-lead plastic leaded chip carrier (PLCC).

The DS1236S-10N+T&R is designed to work primarily with microprocessors, DC-DC converters, digital signal processors, ASICs, and memory devices, providing reliable protection to both digital and analog components. This supervisor can monitor input voltages as low as 0V, and provide a maximum of 12V protection up to 10V, depending on the configuration. Additionally, this supervisor also has internal open-drain logic-controlled outputs, and can be configured to generate interrupts, reset outputs, or other logic functions.

The working principle of the DS1236S- 10N+T&R is relatively straightforward. This supervisor monitors all power supplies, both main and auxiliary. When the voltage is within its normal operating range, the supervisor will continue to operate and maintain the system’s power levels. However, if the voltage deviates from its normal operating range, the supervisor will immediately shut down the system and protect the components. The supervisor will also generate an interrupt to inform any systems monitoring the power supply that a fault has occurred.

The DS1236S- 10N+T&R supervisor is designed to provide comprehensive protection for a wide range of modern applications, including those found in industry, medical, automotive, and consumer electronics. It has an extensive list of features, including an over and under voltage protection, 0V input protection, and loss-of-clock protection. It can monitor power supplies as low as 0V and as high as 10V, and has internal open-drain logic-controlled outputs. Furthermore, the DS1236S-10N+T&R is available in two different packages, an 8-lead PLCC and a QFN package, making it suitable for many different applications.
