BQ4845S-A4NTR Overview
There is an embedded version of real time clocks in the package 28-SOIC (0.295, 7.50mm Width).There is a way to package time clock in the form of a Tape & Reel (TR).This electrical RTC receives its power from the 4.75V~5.5V supply voltage.Electrical real time clocks of type Clock/Calendar are involved.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.Keeping the temperature at -40°C~85°C is essential to maintaining a safe working environment.When operating, Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer can be ensured.Transmitter lines with 28 terminations exhibit the characteristic impedance of the terminating RTC module.5V voltage is present on this electronic component.There are 28 pins on it.The BQ4845 family contains RTCs .Note that the supply voltage is 2.3V~4V for this electrical digital time clock.In Timer or RTC, you can find this component.Real time clocks' output frequency should not exceed 0.032MHz.There is a mounting type Surface Mount specified for the RTC module.A total of 5V power supplies are required to operate it.The real time clock is equipped with 28 pins.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.In order to achieve high efficiency, the supply voltage should be kept at 5V.
