BQ4802YDWG4 Product Details

BQ4802YDWG4 Overview


real time clocks is located in package SOIC.There is the possibility of terminating transmission lines with 28 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.In this case, the voltage supplied to the electronic component is 5V.A total of 28 pins are included in this product.There should be no frequency greater than 0.032MHz in real time clocks' output.Mounting type Surface Mount matches the RTC module.For powering the real time clock, a power supply with a voltage of 5V is used.A total of 28 pins are attached to this real time clock.1 timer real time clocks send out a signal at a preset time based on input signals.Maintaining the supply voltage at 5V is the key to high efficiency.RTC time is advisable to operate at a temperature above 0°C.70°C is the optimal operating temperature.With the minimal voltage of 4.5V, real time clocks are capable of operating.This real time clock operates with a max supply voltage of 5.5V.
