PMIC - Supervisors are generally used for voltage and over-current protection applications. They offer a very reliable, cost-effective and easy to use solution for any project requiring these protection functions. The DS1813-5+ is a digital supervisor with over-current protection, voltage monitoring and over-temperature protection. It provides high system reliability and robust operation while minimizing the effect on system cost.

The DS1813-5+ offers an array of features and integrated protection functions that make it the ideal solution for many applications. The system support and embedded safety features provide high reliability and robustness. The supervisor includes an embedded dual-stage analog-to-digital converter to monitor power rail voltages. It also features two-stage over-current protection for controlling power supplies with current ranges of up to 16 A.

The DS1813-5+ also provides over-temperature protection with a temperature range of up to +135°C. The integrated protection circuitry helps protect system against failure caused by short or open circuits, over-voltage or under-voltage, and current surges. Additionally, the supervisor provides a watchdog timer, adjustable reset threshold, reset output enable, and a reset output enable function.

The DS1813-5+ application fields include power supplies, embedded systems, automotive, wireless communication, and other digital-electronics applications. The supervisor helps provide reliable and robust protection while minimizing power losses and system cost. It also offers flexibility in design as the reset/interrupt control history and output enable can be user-programmable. The supervisor also has ESD protection, thermal shutdown, brown-out protection, and reverse-input protection.

The DS1813-5+ working principle is based on its Analog-to-Digital (A/D) converter. The A/D converter is used to detect voltage levels on the input power rails. The converter takes an analog input from the power rail and converts it to a digital value. The digital value is then compared against the set threshold, and if it exceeds this threshold, the supervisor initiates an interrupt or reset. Additionally, if the input voltage level is below the reset threshold, the reset or interrupt control history is clocked.

The DS1813-5+ is a very reliable and robust PMIC - Supervisors. It provides a wide range of protection functions and integrated features that allow it to be suitable for a variety of applications. These features also help reduce system cost while providing robust performance. Additionally, it has built-in ESD protection, reverse-input protection, brown-out protection and over-temperature shutdown to ensure reliable operation. The DS1813-5+ is ideal for various digital-electronics applications and is an excellent solution for voltage and over-current protection.
