STM818MM6F Integrated Circuits (ICs)

PMIC - Supervisors

The STM818MM6F is an application field of supervisors or power management integrated circuits (PMICs) that provide solutions for regulating, controlling and monitoring the power supply of an electronic system. In particular, the STM818MM6F is a comprehensive solution for designing advanced power management architectures, with control of precise voltages and high efficiency. It offers the user a wide range of features, including voltage monitoring and voltage regulation.

The STM818MM6F is capable of dynamically controlling the output voltage in order to ensure precise regulation and efficient operation. The device also supports different voltage capability levels, predictive voltage startup and shutdown, and shutdown hysteresis. The device has flexible sleep timers, low output capacitance, adjustable LED/relay current, and programmable over-discharge and overvoltage protection.

The operating principle of the STM818MM6F is based on the use of switching regulators where the inductor and switcher, along with the control circuitry, make up the main circuits. The output voltage is controlled by changing the switching frequency, either by using a dedicated controller, the N-PWM, or by using a pulse-width-modulated (PWM) control signal.

The voltage is monitored using an internal or external voltage reference and a voltage comparator. The voltage regulator includes an analog and a digital error amplifier in order to achieve a precise output regulation across a wide range of temperatures, loads and circuit conditions.

The controller of the STM818MM6F monitors the output voltage and compares the feedback signal to an internally set reference. Depending on the difference between the reference source and the feedback signal, the controller will increase or decrease the switching rate to maintain the voltage at the desired level. The STM818MM6F also includes fast transient response, overvoltage and undervoltage protection and others.

In addition to its voltage regulation and monitoring capabilities, the STM818MM6F also includes advanced power management functions, such as an integrated power sequencing and sequencing sleep logic, integrated thermal sensors, adjustable voltage margins and pre-programmed hood ramp.

The STM818MM6F is a complete and highly integrated solution that allows system designers to quickly and easily create advanced power management architectures. With a wide range of features and a comprehensive set of components, it enables designers to easily create systems with high efficiency, precise regulations and superior control.
