Power Management Integrated Circuits (PMICs) are an important technology for advanced control and communications systems. PMICs are highly scalable, low-cost devices that can provide digital control and monitoring of power delivery, voltage and current regulation, thermal management, and more recently, wireless communications.

STMicroelectronics offers a family of Supervisors, or Supervisor Integrated Circuits (SICs). An SIC is a specialized form of PMIC that adds a layer of on-chip safety and protection logic to microprocessors and application-specific integrated circuits (ASICs). The STM690RM6F is a member of the STM family of Supervisors. It is designed to protect microprocessor-based designs and applications from reset and power-on irregularities.

Application Field of STM690RM6F

The STM690RM6F is designed for applications such as industrial controllers, automotive electronics, projectors, and home automation. It is ideal for protecting microprocessor-based designs and applications from power-on and reset irregularities. The STM690RM6F Supervisor also meets the requirements of automotive standard AEC-Q100 and is qualified for use with up to 60V power supply voltage.

The STM690RM6F provides integrated protection for high-end designs, including microprocessor-based systems. With 1.8V to 5.5V operation, it is suitable for environments with a wide range of voltages. It is ideal for powering vehicles, consumer electronics, and industrial control applications. A built-in watchdog and manual reset functionality ensures reliability and manufacturability in harsh power environments.

Working Principle of STM690RM6F

The STM690RM6F Supervisor has a built-in reset timer, which is triggered when the input voltage is below a certain threshold or when the input voltage rises above a certain threshold. When the timer is triggered, the output is forced low, which then triggers the reset signal in the microprocessor or ASIC. This reset signal causes the processor or ASIC to reset its register values, clear any pending instructions, and re-establish its communications link.

Power sequencing is another important feature of the STM690RM6F. The device monitors the power-on and power-off sequences and prevents the voltage from falling below a certain level before the power-off sequence is complete. This protects delicate microprocessors and ASICs from unexpected power-off events.

In addition, the STM690RM6F Supervisor can also monitor the input voltage of the system. If the input voltage is higher than a certain level for a significant period of time, the STM690RM6F will force the output low, triggering a reset signal in the processor or ASIC. This provides over-voltage protection for high-end systems.

The STM690RM6F Supervisor can provide additional safety and protection for microprocessor-based and ASIC-based systems in harsh environments. With its integrated reset timer and power sequencing features, as well as its over-voltage protection, it ensures reliable operation and longer life span. Its wide voltage range and automotive grade qualification make it suitable for a variety of applications.
