BQ4802YDWR Product Details

BQ4802YDWR Overview


A package named 28-SOIC (0.295, 7.50mm Width) contains real time clocks.Tape & Reel (TR) is the packaging method.There is 4.5V~5.5V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.0°C~70°C is the operating temperature.When operating, you can ensure Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer.A transmission line can have a 28 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 5V voltage supplied to it.The RTCs are equipped with 28 pins.BQ4802 is the family name of this object.This electrical digital time clock is powered by 2.4V~4V voltage.There should not be a frequency higher than 0.032MHz in the output.Mounting type for the RTC module is Surface Mount.There is a power supply of 5V used to power the real time clock.28 pins are attached to it.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.Optimal efficiency requires a supply voltage of 5V.
