BQ4845S-A4NG4 Product Details

BQ4845S-A4NG4 Overview


In package 28-SOIC (0.295, 7.50mm Width), real time clocks can be found.In this case, time clock is packaged in the way of Tube.A voltage of 4.75V~5.5V is supplied to this electrical RTC.Electrical real time clock type Clock/Calendar.There is an electronic component mounted in the way of Surface Mount.Ideally, the operating temperature should be -40°C~85°C.During operation, the value of Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer can be ensured.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This electronic component receives a voltage of 5V.There are 28 pins on it.This object belongs to the family BQ4845.There is 2.3V~4V supply voltage for this electrical digital time clock.0.032MHz should be the maximum output frequency.A Surface Mount mounting type is assigned to the RTC module.For the purpose of powering the real time clock, the power supply is set to 5V.The real time clock is equipped with 28 pins.1 timers are control real time clocks that emits a signal after receiving an input signal at a predetermined time.A high efficiency supply voltage should be maintained at 5V.
