Introduction

The STM805TM6E is a comprehensive field-programmable Power Supply IC (PMIC), with capabilities to provide a range of power management functionalities. It is suitable for a number of applications, including control and protection circuitry for a wide variety of products such as PDAs and cellular handsets, particularly those using more energy-efficient CMOS technology. The STM805TM6E has been designed to provide a reliable and cost effective solution for power management and system supervision when applied across a wide variety of applications.

Application Fields for STM805TM6E

The STM805TM6E is primarily suited for applications where low-cost and power efficiency are of paramount importance. These applications can range from embedded systems, where a small form-factor, high efficiency IC is required, to automotive and industrial applications, where the IC can be used to monitor and control the power supply of the system.The STM805TM6E can also be used in a variety of consumer applications and portable devices including personal digital assistants (PDAs) and cellular handsets. In these applications, the STM805TM6E is used to provide power supply and system supervision to ensure system stability and reliable operation.

STM805TM6E Working Principle

The STM805TM6E IC operates based on a range of internal and external peripherals, dependent on the system configuration. The internal peripherals include the on-chip analog-to-digital converter (ADC), the voltage regulator (VR), the reset timer (RT) and the oscillator (OSC).The ADC enables the IC to measure and monitor the input voltage, output voltage and current and provide system diagnostics. The VR is used to maintain voltages in the system, ensuring preset values are set and maintained by controlling the output current and/or external resistors. The RT is used to reset the system when critical levels of voltage or current are exceeded.The OSC sets the frequency of the system, allowing for power management features such as frequency compensation and power-saving modes. If a lower frequency is required, an external oscillator can be used instead.The STM805TM6E also supports external peripherals such as displays, buzzers, buttons, LEDs and switches – all of which are used to provide extended functionality and make the unit easier to use.

Conclusion

The STM805TM6E is an ideal choice for applications that require low-cost and power efficiency, such as embedded systems, automotive and industrial uses and consumer applications. By utilising an on-chip combination of internal and external peripherals, the STM805TM6E is able to provide reliable and cost effective power management and system supervision when applied across a wide variety of applications.
