STM6505SCABDG6F

STM6505SCABDG6F is a type of PMIC - Supervisors. It is used to observe and control various currents, voltages and temperatures in power supplies and systems. DC/DC converters and linear regulators, such as LED drivers, Battery Management Systems (BMS) and various motor drivers, are examples of applications in which the STM6505SCABDG6F can be used.

Typical applications:

• Battery Management Systems (BMS)
• DC/DC converters
• LED drivers
• Motor drivers

General Features:

• On-chip voltage supervisor.
• Input supply voltage range: 5 V – 225 V.
• Configurable watchdog time out.
• Integrated Brown-Out Detector (BOD).
• Low current consumption.
• Integrated temperature sensor.

Working Principle:

The STM6505SCABDG6F is optimized to provide a simple, low-cost solution to monitor and protect power systems. It integrates a voltage supervisor and temperature sensor, both of which work closely with the watchdog timer to detect any sign of malfunction.

The voltage supervisor is responsible for monitoring the input supply voltage. It will trigger a reset when the voltage goes out of range or it detects a voltage brown-out. It also has an active low-voltage input which can be used to trigger an interrupt and alert the microcontroller in case of an abnormal condition.

The temperature sensor is responsible for monitoring the system temperature. It will trigger a reset if the temperature exceeds a certain threshold, or if it falls below another predetermined threshold. The sensor can also be connected to an ADC input on the microcontroller to record temperature readings.

The watchdog timer is used to detect any system lock-up or malfunction. It is configured to issue a reset after a certain amount of time if it is not reset by the micro-controller. This allows the system to continuously monitor itself and recover automatically in case of an error.

Conclusion:

The STM6505SCABDG6F is a versatile PMIC - Supervisors, suitable for a wide range of applications. It combines a voltage supervisor, a temperature sensor and a watchdog timer to provide an easy, low-cost solution to monitor and protect any power system.
