Working Principle

The LTC2935IDC-4 works by performing different functions depending on the voltage level provided to the pin of the IC. When the voltage level is below the threshold level, the IC will monitor the voltage level and switch off the power supply when it reaches a certain level. When the voltage level is above the threshold, the IC will start the power supply and enable the voltage regulator. It will then monitor the voltage level and switch off the power supply when it falls below a certain level. The IC also has an overcurrent protection feature, which protects the system by switching off the power supply when too much current is being drawn.

In addition, the IC has a programmable power enable pin which can be used to enable or disable the power supply. It also has a programmable brownout detection, which will shut off the power supply when the voltage falls below a certain level. The IC can also be programmed to perform a power-on / off sequence, with programmable soft-start and power-on / off delays, as well as a programmable stand-bye delay and reset delay.

Conclusion

The LTC2935IDC-4 is a powerful power management and supervisory device that offers a comprehensive, cost-effective solution to the power management requirements of many applications. By providing accurate voltage regulation, programmable power-on / off sequencing, overcurrent protection and integrated protection against short circuits and over-temperature, this IC is an ideal choice for applications where reliability and safety are of utmost importance. The wide range of package options and its RoHS compliance make this IC suitable for many applications. With its convenient design, the LTC2935IDC-4 is sure to be a popular choice among power management and supervisory device users.
