ADM6711TAKSZ-REEL Datasheet/PDFPMIC - Supervisors
The ADM6711TAKSZ-REEL is a product that falls into the PMIC - Supervisors category. It is an advanced low-cost, low-power supply voltage supervisor created to provide microprocessor reset generation and monitoring of multiple supply voltages. It also has a general-purpose input/output port, which allows for system monitoring, problem diagnosis, and multicolor LED control.
The ADM6711TAKSZ-REEL is an ideal solution for successfully monitoring and detecting low, high, and power-on reset conditions. It features an additional watchdog timer that can be used to detect and respond to the failures of a microprocessor, microcontroller, logic, or peripheral device. This provides enhanced system reliability and allows for efficient power control by providing a prompt system reset when needed.
The ADM6711TAKSZ-REEL has a wide range of applications such as reset and power supply monitoring in consumer appliances and industrial applications. It is also useful in personal computers, data communications and consumer ethernet applications, hard disk drives, and audio applications.
Working Principle
The ADM6711TAKSZ-REEL is designed to monitor the supply voltage levels of a system and respond to low voltage and power-on reset conditions. It has an active low reset output, an active high reset output, and a watchdog output. Reset signals are generated in response to the voltage of the main power supply falling below a predetermined threshold value. An internal hysteresis ensures that false reset signals are not generated when excessive input ripple occurs.
The watchdog timer feature of the ADM6711TAKSZ-REEL provides for system monitoring. In normal operation, the watchdog periodically receives a signal from the microprocessor, microcontroller, logic, or peripheral device. If the signal is not received within a specific time limit, then a signal is sent out, notifying the system of a fault and initiating a reset signal.
The general purpose input/output port of the ADM6711TAKSZ-REEL can be used for system monitoring, problem diagnosis, and LED control. This can be used to debug problems with the system and give an indication of system status.
Conclusion
The ADM6711TAKSZ-REEL is an advanced low-cost, low-power supply voltage supervisor that provides microprocessor reset generation and monitoring of multiple supply voltages. It also has a general-purpose input/output port, which allows for system monitoring, problem diagnosis, and multicolor LED control. The watchdog timer feature provides for system monitoring and fault detection, while the reset output and input/output port enable efficient system reset and system status indication.
