PMIC Supervisors are particularly important in the design of electronic systems. These devices play a key role in ensuring the safe operation of the system and protecting it from catastrophic failure. The DS1236S-10+T&R is a popular supervisor choice for a range of applications and can provide extensive fault protection for both digital and analog circuits. In this article, we’ll take a closer look at the features and working principles of the DS1236S-10+T&R and consider some of the most common applications for this device.

The DS1236S-10+T&R is a memristive supervisor. It is composed of a low-power CMOS integrated circuit (IC) and a thermal fuse, which is connected in series with the IC. The IC monitors the voltage level at VDD, the input power of the system, and the temperature of the device itself. When either or both parameters exceed the current thresholds, the thermal fuse activates, immediately interrupting the power supply.

The DS1236S-10+T&R is capable of monitoring two voltage rails simultaneously and can provide up to two open drain outputs for signal output. It has an input voltage range of 0.9V to 5.5V, with operating temperature limited to -40°C to +85°C and a typical skew of 150ps. High accuracy is provided by an internal voltage reference that can guarantee an accuracy of ±2%, while power consumption is held to a minimum, making this device suitable for energy-constrained designs. In addition, it is compliant with the AEC-Q100 standard.

The DS1236S-10+T&R can provide additional protection against power-on and power-off surges, which can be generated by the insertion and removal of electronic components. It also has an adjustable reset output threshold in order to detect a wide range of input voltage levels, as well as adjustable reset time delay and debounce. A reset output logic can be configured to open-drain active low, open-drain active high, or active high.

The DS1236S-10+T&R is used primarily for system monitoring and fault protection. In particular, it can offer protection from power surges caused by the insertion and removal of components and from rapid extreme voltage fluctuations, as well as providing a reset output signal in the event of a fault condition. It can also be used to reduce audible noise during rapid output voltage transitions, or to provide a reset signal at low temperatures to prevent cold start problems, such as those caused by condensation. The device is usually operated in series with the monitored circuit, making it ideal for use in various fault protection applications such as lithium-ion battery charging and automotive systems.

The DS1236S-10+T&R is also suitable for telecom base stations, industrial control systems, and automotive entertainment systems, where it can provide extended protection to critical components. At the same time, its low power consumption and high accuracy make it well-suited to energy-efficient consumer electronic applications, such as portable medical devices. Overall, this device provides a cost-effective and reliable solution to a wide range of common system protection tasks.
