The ADM6306D344ARJZ-R7 is a high-performance microcontroller embedded reset supervisor and power supply supervisor (PSS) part of the Analog Devices range of PMIC supervisors. This part provides extensibility of the products listed in the ADM6306D344ARJZ-R7 family by allowing designers to implement reset, power failure, and manual reset functions in a robust fashion. It features three independent power-on reset (POR) outputs and one manual reset output.

The ADM6306D344ARJZ-R7 is a type of device called a "supervisor" because it serves as an important tool for microcontroller-based designs. A supervisor provides power-on reset (POR), brownout reset (BOR), manual reset, overvoltage protection, and lowbattery detection, as well as other important functions. With this versatility in mind ADM6306D344ARJZ-R7 is suitable for use in a variety of industrial, commercial, and consumer applications, including portable electronics and PCs.

The ADM6306D344ARJZ-R7 provides two reset pins for system or peripheral reset. A single reset pin may be used to control one of the reset pins on the supervisor chip in order to reset the system or peripheral, depending on which reset pin is used. The other reset pin can be used for system or peripheral reset, as well as manual reset. The supervisor also provides an overvoltage protection input, which can be connected to an external voltage monitor, since the chip provides overvoltage protection with an adjustable threshold voltage.

The ADM6306D344ARJZ-R7 also has an internal power-on reset (POR) circuit, which will ensure that the processor starts up correctly when power is first applied. The reset output of the circuit will be asserted when VDD falls below the power-on reset (POR) threshold. When VDD rises above the threshold, the POR output is de-asserted and the processor will start up.

The ADM6306D344ARJZ-R7 also has an internal brownout reset (BOR) circuit. This circuit detects if the voltage supply to the device drops below the brownout reset (BOR) threshold and asserts the BOR signal if it does. This allows the system to reset itself in the event of a power supply fault. This prevents the system from running with low voltage, which can cause damage to other components in the system or corruption of data.

The ADM6306D344ARJZ-R7 also has a power supply supervisor (PSS) to ensure that the voltage supply to the processor remains correct. The PSS has an adjustable threshold voltage and will assert a reset signal if the voltage supplied to the processor drops below the threshold. This feature allows the system to reset itself if the voltage supply goes below expected levels, thus preventing damage or corruption of data.

The ADM6306D344ARJZ-R7 also provides an adjustable watchdog timeout feature, which can be used to detect system failures. A watchdog timer is a hardware timer on the chip that runs continuously and is designed to reset the system if it does not detect any activity for a certain period of time. This feature is used in many embedded systems to monitor the operation of a controller and reset the system if a certain period of time elapses without any reaction from the controller.

The ADM6306D344ARJZ-R7 is suitable for use in a host of applications, including microcontroller-based devices, embedded systems, and many portable electronic products. It is ideal for mobile applications due to its small size and low power consumption, making it an attractive option for designers looking for a reliable, low-cost device for reset and power management in their products. The part is available in both SOP-8 and TSSOP packages, making it suitable for use in both production and prototype designs.
