The STM6718SFWY6F is a component within PMIC (Power Management Integrated Circuit) – Supervisors category. It is a system level cascadable supervisor solution primarily targeting sensitive systems in highly demanding applications. It ensures microprocessors and other sensitive systems remain within its voltage threshold.

In the market today, Supervisor products generally employ a microcontroller to monitor one or more of the system\'s multiple power domains. With power monitoring being the primary focus of the supervisor, engineers are becoming more conscious of the added value that additional MOSFET support, display support, and system reset functions offer. The STM6718SFWY6F comes underneath the \'supervisors\' name in PMIC and offers a low-power system design to combine the various feature needs from multiple components into one integrated circuit.

The STM6718SFWY6F is an efficient, high-performance supervisor designed to offer the perfect set of features for multiple applications.

Application Fields

The STM6718SFWY6F is a popular choice for systems integrating multiple power domains such as consumer, wireless, and automotive applications. It is designed to be used in applications such as automotive displays, automotive safety, consumer medical devices, consumer storage, set-top boxes and digital TVs. It is also a great companion device for the recently released STM6720FXWY8F supervisor.

The low quiescent current, high accuracy voltage and temperature threshold detectors, an onboard GPMFET switch and a dedicated power-on reset are some of the main features that make the STM6718SFWY6F an all-in-one supervisor solution for many diverse fields. It even comes with a watchdog timer and a two-wire serial interface for programming, triggering alarms, and resetting the system if needed.

Working Principle

The STM6718SFWY6F is designed to detect any power supply fluctuations that may harm the system. The supervisor monitors all power sources connected to the system and continuously measures the voltage and temperature of the system, alerting the user in case of an issue. If a significant voltage drop or temperature increase is detected, the supervisor will shut down the system to protect the chip and other sensitive components.

The STM6718SFWY6F also offers precise detection of out-of-tolerance conditions using dedicated thresholds. It can detect voltage fluctuations down to as low as 80mV for monitoring extra-sensitive digital components, plus temperature ranges from -40 °C to +120 °C.

The STM6718SFWY6F supervisor integrates several specialized features such as an over-temperature detector that can be enabled and disabled by the user. It also offers a ±25 mV accuracy for monitoring more precise and sensitive power levels, as well as an adjustable power-on reset with a precision of 0.5% for optimized system performance.

The device also offers a three-state Reset Output signal, which allows designers to choose between active-low, active-high, or Tri-State, allowing the supervisor to be fully compatible with other components in the system. The supervisor also has a programmable timer and can be used to automatically reset the system if a fault condition persists for too long.

In addition to its superb protection features, the STM6718SFWY6F includes an advanced event detection system. This system will allow designers to protect their products from unexpected events such as voltage spikes, or sudden temperature changes.

The STM6718SFWY6F is thus a powerful, versatile and reliable system supervisor solution, offering unparalleled monitoring, protection, and flexibility for a wide range of applications. Its accessibility, low-power operation, and extra features make it an excellent choice for engineers looking for a reliable, cost-effective solution.
