BQ4802LYDSH Overview
In package 28-SOIC (0.337, 8.56mm Width) with SNAPHAT Sockets, real time clocks is located.As of Tube, time clock is packaged in this way.A voltage of 2.7V~3.6V is supplied to this electrical RTC.Electrical real time clocks of type Clock/Calendar correspond to this real time clock.The position of this real time clock (RTC) on the system board is indicated by Surface Mount.0°C~70°C is the operating temperature.In order to ensure Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer when operating, a certain value has to be set.There are 28 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.3.3V voltage is present on this electronic component.A total of 28 pins are equipped with the RTCs.In terms of RTCs family, RTCs belongs to BQ4802.Keeping in mind that the supply voltage of this electrical digital time clock is 2.4V~4V is important.It falls under the subcategory of Timer or RTC.It should not exceed 0.032MHz as the output frequency of the real time analog clock.There is a type of mounting for this RTC module: Surface Mount.The real time clock is equipped with 28 pins.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.RTC time is essential that the supply voltage remain at 3.3V for maximum efficiency.
