BQ4845YS-A4NTR Overview
Among the packages 28-SOIC (0.295, 7.50mm Width) is where real time clocks can be found.The package is in the form of Tape & Reel (TR).It requires a voltage of 4.5V~5.5V to be supplied.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.This real time clock (RTC) is mounted in the way of Surface Mount.Electronic time clocks should be -40°C~85°C degrees Celsius during operation.When operating, electronic time clocks would be possible to ensure that the value Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer are maintained.With 28 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.This electronic component receives a voltage of 5V.28 pins are attached to it.There are a family BQ4845 associated wit h thare object.2.3V~4V is the supply voltage of this electrical digital time clock.In Timer or RTC, this part is included.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.The mounting type of the RTC module is Surface Mount.A total of 5V power supplies are required to operate it.A total of 28 pins are equipped with the real time clock.When an input signal is received, 1 timers are used to output a signal at a preset time.Maintaining the supply voltage at 5V is the key to high efficiency.
