BQ4802YDW Overview


This can be found in the package 28-SOIC (0.295, 7.50mm Width).There is a way to package time clock in the form of a Tube.In this electrical RTC, the supply voltage is 4.5V~5.5V.The electrical real time clock belongs to the type Clock/Calendar.In this case, Surface Mount is the way this part is mounted on the systemboard.A safe operation requires a temperature of 0°C~70°C at all times.Electronic time clocks are possible to make sure that Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer are maintained when operating.When a transmission line is terminated with 28 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.In the case of this RTC real time clock, there is 5V voltage supplied to it.With its 28 pins, it has the necessary functions.There are only one family in which RTCs belongs, and that are BQ4802.The supply voltage of this electrical digital time clock is 2.4V~4V.The RTCs belongs to the Timer or RTC subcategory.There should be no more than a 0.032MHz frequency at real time clocks' output.A mounting type of Surface Mount has been specified for this RTC module.A power supply of 5V is used to power it.There are 28 pins on it.Upon receiving an input signal, 1 timers output a signal at a preset time.The supply voltage should be maintained at 5V for high efficiency.The outputs are set to 8.
