BQ4845S-A4TR Overview

There is an embedded version of real time clocks in the package 28-SOIC (0.295, 7.50mm Width).This package has a package type of Tape & Reel (TR).Electrical RTCs such as this have a 4.75V~5.5V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.Electronic time clocks are recommended to operate at a temperature of 0°C~70°C.If Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer is ensured when operating, then the operation will be successful.There are 28 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 5V which is provided to it.A total of 28 pins are attached to this RTCs.There are a family named BQ4845 that consarets of the RTCs .In this electrical digital time clock, the supply voltage is 2.3V~4V.Ensure that the output frequency does not exceed 0.032MHz.In this case, the RTC module is mounted in the way of Surface Mount.As a power supply for the real time clock, a value of 5V is used.A total of 28 pins are equipped with the real time clock.Following an input signal, there are 1 timers that output a signal at a preset time.RTC time is essential that the supply voltage remain at 5V for maximum efficiency.
