BQ4845YS-A4 Overview
28-SOIC (0.295, 7.50mm Width) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 4.5V~5.5V.It is a Clock/Calendar type electrical real time clock.A part of this electronic RTC module is mounted in the way of Surface Mount.Electronic time clocks should be 0°C~70°C degrees Celsius during operation.Electronic time clocks are possible to guarantee Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer when operating.Transmission lines can be terminated with 28 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 5V supplied to it.28 pins are present on it.BQ4845 are RTC s family.2.3V~4V is the supply voltage of this electrical digital time clock.A frequency of 0.032MHz should not be exceeded by real time clocks' output.There is a mounting type of Surface Mount for this RTC module.The power supply is 5V.With 28 pins, it is equipped.1 timers are in the real time clock that outputs a signal in response to an input signal.Maintaining a voltage of 5V will result in high efficiency.
