A62140007 or better known as A6214 is a 2.5V to 6V low drop-out voltage supervisor from Diodes Incorporated. It is a popular choice for use as a reset generator in many industrial and consumer applications. Its power output range allows the A6214 to be used in automotive, industrial and consumer level electronic devices. The A6214 is a supervising circuit with a power on reset feature and open drain reset output. Its main purpose is to continuously monitor supply voltage conditions (Vcc), to indicate power on or off, and to generate a reset pulse on power-up and power-down.

The A6214 supervisor not only provides a reset output, it also provides a reset generation from a supply voltage (Vcc) driven by an external capacitor. The A6214 operates as a simple comparator and its internal circuitry produces a reset pulse only when the voltage supplied to its input terminal exceeds the factory programmed threshold voltage (available in fixed voltage versions). This can be useful when a system needs to reset itself after a period of extended power outage, or when the main supply input voltage changes and a reset should occur. This feature saves the user from having to manually reset the system after a power down event.

The A6214 supervisor features a low power operation with a power down reset mode which allows the reset pulse duration and the output voltage to scale down accordingly when the supply voltage is significantly reduced. This reduces the power consumption in systems and prevents any disruption in operation due to a sudden supply voltage drop. The A6214 is designed for trouble-free operation with minimum external components. The shutdown pin allows for an external control signal to shut down the device reducing the overall power consumption of the system. It also provides an active-low reset output.

Applications of the A6214 supervisor include but are not limited to embedded systems, automotive, industrial and consumer electronics. It is capable of interfacing with microcontrollers, digital signal processors, microprocessors and other system components to provide a valid power-on reset. It is commonly used in PCs, low power systems, battery powered systems, industrial control systems, disk drives and handheld communication devices.

As far as the working principle of the A6214 supervisor is concerned, it is a very simple two terminal device with one input and one output terminal. The VCC input is connected to the power supply so that the internal comparator can compare the reference voltage which has been factory programmed against the supply voltage. If the supply voltage falls below the reference voltage, the A6214 signals its reset output which is an open drain that can be connected to a ground line. The reset output will remain in the active state as long as the supply voltage remains below the factory pre-set voltage.

On power up, the A6214 will wait until the supply voltage reaches the factory programmed threshold and then it will generate a reset pulse. The pulse duration is factory programmed to ensure that the power-on sequence is not interrupted by the reset pulse. The reset output is active-low throughout the power-on sequence and then goes high when the A6214 is ready to accept commands from system components.

In summary, the A6214 is a low drop-out voltage supervisor from Diodes Incorporated which can be used in a variety of industrial and consumer applications. It provides a reset output as well as a reset generation from a supply voltage (Vcc) driven by an external capacitor. Its power output range allows the A6214 to be used in automotive, industrial and consumer level electronic devices. The A6214 has a shutdown pin that allows an external control signal to shut down the device and reduce power consumption, and it can detect when the VCC voltage is below the pre-set voltage, generating a reset pulse.
