PMICs (Power Management Integrated Circuits) are integrated circuits designed to provide automated level control of voltage and current in a wide variety of power applications. Among the more specialized PMICs available, Supervisors are single-chip systems that monitor and control electrical power through the oversight of power-related operations. The APX803S00-40SR-7 Supervisory IC is a prime example of the flexibility and reliability provided by today’s cutting-edge Supervisors.

The APX803S00-40SR-7 Supervisory IC is a single-chip solution for monitoring and controlling voltage levels in power supplies and peripheral circuits. It is capable of regulating up to 7 supply and 5 system/peripheral voltages and comes with programmable back-up voltage protection, thermal shutdown protection, reset delay and monitoring activity control, among other features. Its ability to detect and respond quickly to power good requirements and its wide range of on-chip features make it an ideal solution for controlling voltage levels in high-power applications.

The working principle of the APX803S00-40SR-7 Supervisory IC is based on current sensing. The IC uses an on-chip voltage divider to detect the voltage of up to 7 different supply and 5 system/peripheral voltages, and then uses the output current to sense the voltage level. The voltage divider is adjustable and can be used to set the desired voltage level for each circuit. If the voltage level goes below the set level, the IC triggers a reset signal to reset the concerned circuits. The IC also has an adjustable voltage pull-up (when the voltage falls below a certain level), as well as an adjustable voltage drop-down (when the voltage reaches a certain level).

The APX803S00-40SR-7 Supervisory IC also comes with advanced thermal shutdown protection. The thermal shutdown feature shuts down the entire IC when a certain temperature is reached, preventing damage to the IC and the rest of the circuity due to overheating. Additionally, the IC features a programmable reset delay, a “power good” output, and monitoring activity control (to prevent and detect errors) in order to ensure that the correct power levels are provided to the rest of the system.

The APX803S00-40SR-7 Supervisory IC is an ideal solution for power control and management in a wide range of applications, such as computers, automotive systems, industrial systems, and medical devices. Its ability to detect and respond quickly to power good requirements, its wide range of on-chip features, and its adjustable thermal and voltage protection features make it a versatile and reliable component in power management and control solutions.
