BQ4845YS-A4N Overview
A package named 28-SOIC (0.295, 7.50mm Width) contains real time clocks.As you can see, time clock is packaged as if time clock were in the form of Tube.This electrical RTC is powered by a voltage that is 4.5V~5.5V at the time of installation.This electrical real time clock has the type Clock/Calendar.A part of this electronic RTC module is mounted in the way of Surface Mount.Electronic time clocks are recommended that the operating temperature be -40°C~85°C.As long as Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer is ensured when operating, the system will work properly.When a transmission line is terminated with 28 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.In the case of this RTC real time clock, there is 5V voltage supplied to it.As it has 28 pins, it is equipped with the necessary features.BQ4845 are the family name of RTCs .2.3V~4V is the supply voltage of this electrical digital time clock.RTCs in the Timer or RTC subcategory are available.The output frequency should not exceed 0.032MHz.A mounting type of Surface Mount has been specified for this RTC module.The power supply is 5V.It is equipped with 28 pins.1 timers are in the real time clock that outputs a signal in response to an input signal.RTC time is essential that the supply voltage remain at 5V for maximum efficiency.
