PMIC - Supervisors

PMIC (Power Management IC) supervisors are typically single-chip peripheral controller devices that are used to help optimize the design of power management systems. Supervisors provide logic and monitoring of power supply levels, system shut-down, voltage and temperature protection, as well as over-voltage protection. They help improve the reliability and performance of a power management system, while reducing the total component count, board space and overall power consumption.The STM6904TZEDS6F supervisor operates using a low-side current sensing technique to monitor output current and ensure its equivalent capabilities for both single-ended and differential mode. It utilizes a fixed circuit protection threshold for both low-side and high-side switches, to provide a robust and reliable solution for many power management applications.The STM6904TZEDS6F supervisor is designed to improve system reliability, reduce the possibility of catastrophic energy losses, and increase the system\'s recovery time in the event of an over current situation. It provides a timed or permanent overload protection and offers overload shutdown, as well as current limit functions. Its multiple-level protections and thermal limiting ensure reliable shut down upon detection of current over-stress and temperature out of range.The STM6904TZEDS6F supervisor contains a digital-to-analog (D2A) converter, which translates the input digital signal into an analog voltage. This reduces the need for a digital-to-analog (D2A) conversion circuit, which traditionally is used in power management systems. The on-board dedicated reset function allows the supervisor to detect anomalous signals and shut down the power supply in the event of a fault.The STM6904TZEDS6F supervisor offers protection against short circuit, over current and thermal-limit protection. The CMOS-compatible logic input voltage is adjustable from 3V to 18V, making it suitable for many applications. The STM6904TZEDS6F also features an adjustable reset time to adjust the system\'s recovery time.The STM6904TZEDS6F supervisor is designed for use in multiple industry applications such as computing, consumer electronics, automotive, motors, industrial control, white goods and smart meters. It can be used to monitor current in DC-DC converters, such as buck and boost. The supervisor is also capable of providing an undervoltage and overvoltage shutdown and protection in adjustable voltage regulators, switching power supplies, load switches and circuits with back-to-back MOSFETs.In summary, the STM6904TZEDS6F supervisor is an innovative device that offers a flexible and reliable solution for monitoring, controlling and protecting power management systems. It provides low-side current sensing, comprehensive protection capabilities and combines a digital-to-analog conversion circuit into a single device to reduce system components and power consumption. With its adjustable logic voltage, adjustable reset time and multiple-level protection features, the STM6904TZEDS6F supervisor is an optimal choice for many power management designs.
