BQ4802LYPWG4 Overview
In package 28-TSSOP (0.173, 4.40mm Width), real time clocks is located.As a result, time clock is packaged in the same way as Tube.A voltage of 2.7V~3.6V is required for the supply of this electrical RTC.Electrical real time clocks of type Clock/Calendar correspond to this real time clock.Surface Mount indicates how this real time clock (RTC) is mounted.Maintaining a constant temperature of 0°C~70°C is essential for safe operation.When operating as part of a process, electronic time clocks are possible to ensure that Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer are maintained at all times.28 terminations result in transmission lines having the characteristic impedance of a RTC module terminating them.This RTC real time clock's supply voltage is 3.3V.It is equipped with the necessary features since it has 28 pins.Thare RTCs em are part of the family BQ4802.Note that the supply voltage is 2.4V~4V for this electrical digital time clock.There should be no more than a 0.032MHz frequency at real time clocks' output.Amounting type Surface Mount is the one associated with the RTC module.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 3.3V.
