S-80918CLPF-G6NTFU

The S-80918CLPF-G6NTFU is a member of a family of general-purposesupervisors produced by Intersil Corporation. This particular type ofsupervisor is part of the Power Management Integrated Circuit (PMIC)suite of products, and is designed to protect microcontrollers,microprocessors, or other integrated circuits by monitoring their powerand reset functions. It is a two-pin supervisor, with two sets of control pins: one is a reset pin, and the other is a power supplymonitoring pin.

The S-80918CLPF-G6NTFU monitors the power supply voltage, and willissue a reset signal if the voltage falls below a predeterminedthreshold. It is available in a 2.5V to 5.5V operating range and canwithstand up to 25mA of ripple noise on its power supply. Thesupervisor also has a backup battery input pin, allowing it to functioneven when the main power supply is switched off. The reset pin has acapacitive load of up to 0.3uF, and the monitor pin has a typicalvoltage accuracy of less than 5%. Additionally, the S-80918CLPF-G6NTFUhas an on-chip temperature sensor and a shutdown comparator, which canbe used to monitor temperature and issue a reset signal when needed.

The S-80918CLPF-G6NTFU is typically used in embedded systems andother applications where reliable power management is essential. It isideal for battery powered or automotive applications, as it iscapable of handling a wide range of voltages. It can also be used tomonitor other power sources such as AC or DC power supplies or isolatedpower supplies. In addition, it is also suitable for applications, suchas LED backlighting, where power and temperature stability areimportant.

In operation, the S-80918CLPF-G6NTFU protection circuit functions bycomparing the voltage on the power supply monitoring pin to thevoltage on the reset pin. If the voltage on the power supplymonitoring pin is below the reset voltage, the reset signal is issued,and the power is shut off. The reset signal can be asserted by eitherthe voltage monitor, the temperature monitor, or the shutdowncomparator. Additionally, the reset signal can be used to cause afall-back into a safe mode, preventing an uncontrolled reboot of the system.

The S-80918CLPF-G6NTFU has a typical quiescent current of less than1μA and a reset time of 10μs. It also features an overtemperaturelockout feature, allowing it to shut down the system if the temperatureexceeds a certain level. This supervisor is available in a small TSSOPpackage, making it suitable for a wide range of embedded applications.

The S-80918CLPF-G6NTFU is an essential component of a reliable powersupply system, and is a key component of Intersil Corporation\'s PMICsuite of products. Its ability to monitor a wide range of power sourcesmakes it ideal for applications requiring reliable power management andreliable protection against overvoltage, undervoltage, and overtemperature. Its compact package makes it suitable for a variety ofembedded systems and applications where power management is of paramount importance.
