PMIC - Supervisors: STM795TM6E application field and working principle

The STM795TM6E is an integrated Supervisory Circuit developed by SGS-Thomson Microelectronics, especially suitable for mobile systems such as cell phones and PDAs. This Device provides a complete power on reset and power down protection, as well as system level functions including voltage monitoring, active-high reset and active-low reset output, and push-button debounce.

The STM795TM6E is available in three different packages: TSSOP, SOIC and MSOP. All packages are specified for a wide operating temperature range of -40°C to +85°C. This Device is available in 1.6V and 1.9V (3.3V) versions.

Application Field

The STM795TM6E is suitable for providing complete system level protection for mobile applications (e.g.,cell phones, PDAs), using its integrated low voltage detector (LVD) and push-button reset features. It can also be used in other applications requiring advanced system level protection such as PDAs, high-end cellular phones and digital cameras.

Working Principle

The STM795TM6E provides a complete system power down protection solution based on its integrated low voltage detector and push-button reset features. When the input voltage reaches the voltage detection threshold of the device, the low voltage detector (LVD) begins to monitor the voltage levels. If the input voltage reaches any of the pre-selected thresholds, the LVD will send an active-low reset signal to its output.

The STM795TM6E also has a push-button reset feature. When the push-button is pressed, the reset signal will be activated. This reset signal can be used to reset any of the system level peripherals, such as the flash memory, RAM or microcontroller.

The STM795TM6E also includes an active-low reset output, which is active whenever the voltage is below the threshold. This reset signal is used by the system to keep the peripherals in a low-power state until the power supply voltage rises above the reset voltage threshold.

The STM795TM6E is capable of providing a wide array of features, such as push-button reset, power-on reset, system-level control and voltage monitoring. This Device is extremely useful for mobile applications, as it allows the system to be protected against unpredictable voltage drops and power losses. In addition to providing full system protection, the STM795TM6E also offers advanced features, such as an active-low reset output and push-button reset.

Conclusion

The STM795TM6E is a very powerful Supervisory Circuit, capable of providing a complete system level protection solution for mobile applications. It is available in 1.6V and 1.9V (3.3V) versions and is specified for a wide operating temperature range of -40°C to +85°C. This Device provides advanced features such as low voltage detector, push-button reset, active-high reset and active-low reset output. With its multiple functions and advanced performance, the STM795TM6E is an ideal choice for system level protection applications.
