STM706M6E

Power management integrated circuits (PMICs) are fundamental components of most modern electronic devices. PMICs provide an array of services to keep a device in an optimum state of power consumption, including regulating the output of power, converting DC power to AC, ensuring thermal stability and protecting against voltage transients. As the name suggests, they integrate multiple power management functions into a single integrated circuit, allowing engineers to save board space, cost and design complexity. One of the most powerful PMIC solutions is the STM706M6E.

The STM706M6E is a high-performance power management integrated circuit (PMIC) specifically designed for low-power or mobile electronic applications such as laptops, tablets, smartphones and wearables. This 6-channel power supervisor integrates overvoltage and undervoltage protection, overcurrent protection and real-time monitoring and reporting of various environmental parameters (such as temperature, humidity and power consumption). It boasts ultra-low quiescent current, high efficiency and fast output response, with a wide operating temperature range of -40 to +105 degrees Celsius. It also features an enhanced detection algorithm for detecting overcurrent events.

The STM706M6E takes the high-performance combination of ultra-low current consumption, high efficiency and real-time reporting to the mobile world. Thanks to its superior performance, the STM706M6E is not only suitable for portable applications but also can operate in a car, making it ideal for automotive applications such as advanced driver assistance systems (ADAS) and vehicular infotainment systems.

At the heart of the STM706M6E is a dedicated IC offering six channels of over-voltage, under-voltage and over-current protection. The IC continuously monitors input and output voltages across the six channels and will shut down the circuit in the case of an unsafe (or out-of-specification) condition. The IC also provides short-circuit rest capabilities, allowing the user to optionally enable or disable it on a per-channel basis. The IC also features real-time reporting features such as temperature, humidity, output current and power consumption.

The STM706M6E is a highly integrated device with one IC capable of integrating six power management internal blocks into a single IC. Each block is capable of operating independently, allowing for flexible current range selection and features. The IC includes an adjustable voltage supervisor, DC-DC buck/boost converter, a over-voltage and under-voltage protection circuit, a PWM oscillator, an AC filter, a test counter, and a crystal oscillator.

The adjustable voltage supervisor offers multiple adjustable thresholds and allows the user to select the trip point, reset delay and hysteresis. The DC-DC buck/boost converter provides high efficiency, low ripple and low noise output voltage. Over-voltage and under-voltage protection is provided by the integrated OVP/UVP circuit, which offers multiple adjustable trip points and adjustable response times. The PWM oscillator offers adjustable frequency and dead-time control, enabling optimized power supply designs.

The STM706M6E is an advanced power management integrated circuit offering superior performance, power savings, and superior thermal management. It is ideal for low-power or mobile applications such as laptops, tablets, smartphones, and wearables and automotive applications such as advanced driver assistance systems (ADAS) and vehicular infotainment systems. It offers exceptional protection against over-voltage, under-voltage, and over-current events, and comprehensive real-time reporting features (temperature, humidity, output current, power consumption). It also provides the flexibility of multiple current range selection, adjustable voltage supervisor, DC-DC buck/boost converter, over-voltage and under-voltage protection circuit, a PWM oscillator, an AC filter and test counter. All these features make the STM706M6E an ideal solution for power management in a wide range of applications.
