BQ4802LYDWR Overview


There is a package 28-SOIC (0.295, 7.50mm Width) that contains real time clocks.The package is packaged in the way of Tape & Reel (TR).There is 2.7V~3.6V voltage supply for this electrical RTC.An electrical real time clock of this type is called a Clock/Calendar.There is an electronic component mounted in the way of Surface Mount.The operating temperature should be 0°C~70°C.When a command are executed, electronic time clocks are possible to maintain Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer in order to maintain the current state.In the case of 28 terminations, transmission lines have the characteristic impedance of the terminating RTC module.RTC real time clocks like this have a 3.3V supply voltage.As it has 28 pins, it is equipped with the necessary features.As a member of the BQ4802 family, RTCs belongs to them.Note that the supply voltage is 2.4V~4V for this electrical digital time clock.It falls under the subcategory of Timer or RTC.The frequency of real time clocks' output should not be higher than 0.032MHz.A mounting type of Surface Mount has been specified for this RTC module.28 pins are present on it.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.High efficiency requires a 3.3V supply voltage.
