PMIC - Supervisors

STM6717SYWY6F is a highly integrated Chip On Board (COB) module for the industry-leading PMIC - Supervisors. Developed for the industrial, automotive, and consumer markets, STM6717SYWY6F offers an all-in-one solution for a wide range of applications from professional grade entertainment systems and home automation to critical infrastructure and power management.

Designed with multiple input/output (I/O) manipulation functions, STM6717SYWY6F is an easy to use and versatile device. It features two high frequency (HFX) and two low frequency (LFX) pulse waveforms with a single pulse output. This makes it suitable for a wide range of applications such as overvoltage protection, delay ON/OFF, adjustable operating points, variable frequency regulation, and temperature monitoring.

The integrated HFX generation allows the module to be used as a supervisory circuit for industrial and automotive systems including motor drivers, power supplies, sensors, and actuators. With its adjustable delay time, non-blocking feature, and auto-disconnection capability, STM6717SYWY6F works great as an addition to embedded microcontrollers or other digital system components.

The module includes a watchdog timer (WDT) feature with adjustable cycle length. This enables it to detect any system faults and prompt a reset operation. For the automotive market, STM6717SYWY6F is also capable of monitoring temperature fluctuations and providing accurate data about the same.

STM6717SYWY6F offers excellent power management features. It is characterized by a wide operating temperature range from -40°C to +125°C, low current consumption in standby mode (as low as 10µA), and high transient voltage protection. The module also supports an extended supply voltage range from 3V to 30V and an I/O voltage range from 0.5V to 6V.

In terms of circuit design, STM6717SYWY6F is designed with a high level of integration and low power consumption. It enables faster communication speeds with an integrated 32-bit microcontroller. The module also includes a programmable digital counter, allowing for a wide range of programming options. For the environmental protection, STM6717SYWY6F features overload protection and an overload warning indicator.

Working Principle of STM6717SYWY6F

STM6717SYWY6F uses a Pulse Width Modulation (PWM) control method to regulate the output voltage. It is designed to be used with a single pulse output, which is generated by a high frequency (HFX) pulse waveform. The module then uses the pulse waveform to regulate the output voltage. The operating parameters of the output voltage can be adjusted via the integrated variables, such as the duty cycle, frequency, and voltage limit.

In addition, STM6717SYWY6F has two low frequency (LFX) pulse waveform inputs. These inputs can be used to control the module’s output voltage. The voltage level at each LFX input can be adjusted through an onboard register or through an external control circuit. The duty cycle of the output voltage is determined by the amount of voltage present at the two LFX inputs.

The module also has a safe operating power level that is adjustable. This adjustable power level can be used to limit over-voltage or over-current situations to protect the connected system from potential damage. The module also incorporates a watchdog timer (WDT) feature that works as a safeguard against any system faults.

Conclusion

STM6717SYWY6F is a highly integrated Chip On Board (COB) module for the popular PMIC - Supervisors. Featuring a wide range of powerful features including adjustable operating points, variable frequency regulation, temperature monitoring, and an adjustable delay time, STM6717SYWY6F is an ideal solution for a wide range of applications, from professional grade entertainment systems and home automation to critical infrastructure and power management. With a high level of integration, low power consumption, and adjustable Safe Operating Power (SOP) level, STM6717SYWY6F is a great choice for industrial and automotive applications.
