FT7511L6X Integrated Circuits (ICs)

FT7511L6X is a supervision device in the PMIC - Supervisors family, specifically designed to monitor supply voltage and require stable power sequence. The FT7511L6X can provide minimal external component supervision and sequencing by monitoring power supply voltages and sequencing external supplies. It can detect conditions such as undervoltage, overvoltage, power-on reset(POR) and power-fail reset (PFR).

Application Field

FT7511L6X can be used for voltage monitoring and sequencing for many different devices and applications. In consumer electronic products, for example, it can protect devices from overvoltage and undervoltage, which continue to increase in complexity and require ever more reliable power supplies. FT7511L6X is used in a variety of applications including embedded systems, DTV and Set-top-box, Networking, Computing, and Analog/Digital Conversion. Furthermore, in automotive power supply applications it can supply the system power, monitor the power supply, and reset the system when the voltage is out of the specified range.

Working Principle

FT7511L6X is designed to detect when an input voltage drops to or rises above a user-defined threshold. When FT7511L6X is activated by an input voltage, it initiates a power-on reset (POR) or power-fail reset (PFR) signal. It comes with two input channels and two corresponding output channels, both of which have a choice of operating values.

When the input voltage drops to or rises above a predefined threshold, the output signal is triggered and the output device is powered. The output signal can be used to monitor the power supply state or to trigger the power supply sequencing step. It also has the ability to detect voltage drop and voltage rise events, which can generate the reset housekeeping signals required by the associated devices.

FT7511L6X has all sorts of built-in safety features that help protect your valuable hardware and ensure proper operation. It has temperature-compensated power-on and power-off delays, undervoltage and overvoltage lockout, as well as over-current and thermal shutdown. Additionally, FT7511L6X has three different power supply states: power-on, power-off, and power-down.

Conclusion

The FT7511L6X is a powerful and versatile voltage monitoring and sequencing device that can be used in many different application areas. Moreover, it can provide enhanced protection and reliability for your valuable hardware by detecting overcurrent and overvoltage conditions, as well as temperature-compensated power-on and power-off delays.

All of these features combined make the FT7511L6X a fantastic solution for any devices and applications that require highly reliable power supplies.
