BQ4802LYDWG4 Product Details

BQ4802LYDWG4 Overview


In the package SOIC, you will find real time clocks, and you will be able to install real time clocks.Transmitter lines with 28 terminations exhibit the characteristic impedance of the terminating RTC module.There is 3.3V voltage supplied to this RTC real time clock.The reason for this is that, due to the fact that it has 28 pins, it has the necessary features.Timer or RTC is the subcategory in which the RTCs belongs.It should not exceed 0.032MHz as the output frequency of the real time analog clock.A mounting type of Surface Mount has been specified for this RTC module.A total of 28 pins are attached to this real time clock.1 timer real time clocks send out a signal at a preset time based on input signals.Maintaining the supply voltage at 3.3V is the key to high efficiency.RTC time is advisable to operate at a temperature above 0°C.70°C is the optimal operating temperature.With the minimal voltage of 2.7V, real time clocks are capable of operating.This real time clock operates with a max supply voltage of 3.6V.
