A PMIC - Supervisors, S-80151BLPF-JFCTFG is a device used to reset microprocessor or Interface Circuit when a power-on reset is needed. The device contains both dedicated reset and low voltage reset shutdown circuits. The S-80151BLPF-JFCTFG has a higher tolerance to ESD, withstanding greater than 10KV per the JEDEC standard, to help protect the system from allowing false resets.

In terms of application fields, S-80151BLPF-JFCTFG supervisors are most commonly used in consumer electronics. This includes products such as televisions, home entertainment systems, computers, gaming consoles, smart phones and digital cameras that rely on microprocessors and interface circuits. The device is also used during new system Design-in, as well as providing a replacement policy in an existing system. Therefore, S-80151BLPF-JFCTFG can be used as a reliable power-on reset circuit in virtually any system.

The S-80151BLPF-JFCTFG works by monitoring the power supply and detecting power-on reset conditions. It has a delay timer available, which is adjustable up to 200 milliseconds using two external resistors. This is able to provide a user-selectable delay timeout for systems that need to stabilize their power supplies before resetting. The device is also equipped with an enable/disable input, which can be used to disable/enable the reset line. The device also comes with a manual reset button which can be used to manually reset the microprocessor.

For extreme power-on reset scenarios, S-80151BLPF-JFCTFG is able to detect when voltage drops below a certain level and rapidly trigger a reset signal to the microprocessor. Furthermore, the device can also detect when voltage is slowly decreasing, such as in a brown-out condition where shut-off is needed before the voltage drops below an acceptable threshold. This can help prevent an unexpected shutdown of the system.

Working in unison with the extremely low voltage detection and voltage monitoring circuits, the S-80151BLPF-JFCTFG also contains a soft-start circuit. This ensures that the power-on reset signal is not triggered at too high a voltage, protecting the microprocessor from being turned on too quickly.

The S-80151BLPF-JFCTFG also comes with an active-high open collector reset output signal and an open drain reset output signal. The output has a low impedance load, ensuring that it can be used to trigger better response times for microprocessor resets. Furthermore, the reset signal is held high until the power-on reset conditions are detected and the device completes the power-on reset sequence. The device also comes with a current-limit protection circuit, ensuring that it is not damaged if too much current is applied.

In conclusion, the S-80151BLPF-JFCTFG offers a reliable and robust power-on reset solution that is suitable for any design-in and replacement policy system. It offers high tolerance to ESD, adjustable delay timer, enable / disable input, manual reset button, and extremely low voltage detection and voltage monitoring circuits. All of these features make the S-80151BLPF-JFCTFG an attractive choice as an emergency power-on reset supervisor.
