PMIC, short for "Power Management Integrated Circuit", is a type of integrated circuit responsible for regulating power in a device. PMICs are typically used in applications that require a wide range of voltages and often need to accommodate to more complex power flows. A common application for PMICs is in power supervisions. Supervisors are a component that monitors various conditions related to the power supply of a system and responds to it accordingly. This can include common voltage sense, temperature sense, system reset, brownout detection and Error Check & Correct (ECC).

The Microchip DS1817-20 is a 20-pin supervisory circuit specifically designed to monitor and protect against power supply faults. It supports an adjustable brown-out detection limit with an integrated reset and allows for a reduced component count by providing three separate voltage monitoring channels, each with selectable trip levels, and temperature monitoring. This supervisor also offers the added benefit of a real-time clock (RTC) and a non-volatile memory storage with 40 bytes of user-programmable EEPROM. The DS1817-20 is ideal for use in embedded systems where cost and space are critical as it easily and accurately monitors and responds to power supply conditions.

The DS1817-20 is ideal for use in applications including industrial automation, battery systems, medical and portable equipment, servers, and many other embedded systems. The DS1817-20 provides the system designer with a variety of features and options to monitor and control the power supply system, which can be used in any of these applications. In order to ensure reliable operation of the embedded system and to protect it from power supply fluctuations, the DS1817-20 provides a wide range of voltage monitoring and brownout detection, programmable reset timeouts, temperature monitoring, non-volatile memory storage, and RTC/calendar feature.

The DS1817-20 is designed to monitor a wide range of voltage levels and temperatures, and can detect any issues or changes. It comes with three selectable voltage sense channels to monitor voltages between 2.1V and 5.5V, and a built-in temperature monitor with a programmable temperature threshold. The DS1817-20 also provides a Brown-Out detect (BOD) level programmable between 0.9V and 5.2V. It can also detect current limits and disable power to the system if a current limit is exceeded.

The DS1817-20 uses an analog-to-digital converter (ADC) to monitor the voltage and temperature levels of the power source. If the voltage level or temperature exceeds the pre-set thresholds, the supervisor sends out an alarm. This alarm can be used to reset the system or disable power to the system, depending on how it is programmed.

The DS1817-20 also features a real-time clock (RTC) with a built-in calendar, allowing it to keep track of time and date. This can be used in applications that require time- dependent operations. Additionally, the supervisor has 40 bytes of user- programmable EEPROM memory, allowing it to store any data that needs to be kept or shared across multiple systems.

Overall, the Microchip DS1817-20 is an ideal choice for designers looking for a comprehensive power supervisor solution. Its wide range of monitoring capabilities and its integration of RTC and EEPROM memory make it a valuable addition to any embedded power supply system.
