BQ4845YS-A4G4 Overview


28-SOIC (0.295, 7.50mm Width) is where you'll find real time clocks.Basically, time clock is packaged in a way that is equivalent to Tube.To supply this electrical RTC, a voltage of 4.5V~5.5V is required.An electrical real time clock of type Clock/Calendar can be said to be this one.A part of this electronic RTC module is mounted in the way of Surface Mount.Electronic time clocks are recommended to operate at a temperature of 0°C~70°C.During the course of operation, Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer can be ensured.There are 28 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.There is 5V voltage supplied to this RTC real time clock.28 pins are present on it.The family to which RTCs belongs are BQ4845.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 2.3V~4V.Timer or RTC includes this part.There should be no frequency greater than 0.032MHz in real time clocks' output.Amounting type Surface Mount is the one associated with the RTC module.In order for it to be powered, it requires a power supply of 5V.With 28 pins, it is equipped.When an input signal is received, 1 timers are used to output a signal at a preset time.Optimal efficiency requires a supply voltage of 5V.
