BQ4845YS-A4TR Overview
The package 28-SOIC (0.295, 7.50mm Width) contains real time clocks.Tape & Reel (TR) is the way in which time clock is packaged.Its supply voltage is 4.5V~5.5V.This electrical real time clock has the type Clock/Calendar.Surface Mount is the way this real time clock (RTC) is mounted on the system board.There should be a temperature of 0°C~70°C during the operation.When operating, you can ensure Alarm, Daylight Savings, Leap Year, Supervisor, Watchdog Timer.Transmission lines can be terminated with 28 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.5V is the supply voltage of this RTC real time clock.A total of 28 pins can be found on it.There are a family BQ4845 associated wit h thare object.The voltage supply of this electrical digital time clock is 2.3V~4V.There are such RTCs in Timer or RTC subcategory.Neither real time clocks' output frequency nor real time clocks' response frequency should exceed 0.032MHz.The RTC module is mounted with mounting type Surface Mount.There is a power supply of 5V used to power the real time clock.There are 28 pins on it.An input signal is received by 1 timers, which output a signal after a preset time.RTC time is important to maintain the supply voltage at 5V in order to maintain high efficiency.
