  • BQ24075T as per schematic is R8 needed?

    Other Parts Discussed in Thread: BQ24075T Hi, working out the resistor values for the NTC circuit I thought I'd do the sums to calculate the resistor divider values. My input parameters are as follows: Vin = 4.77V Rhot = 4.926k; 45degC threshold…

  • BQ24075T: Capable of supporting lower charge currents with same accuracy as bq2407x (non-T)?

    Part Number: BQ24075T Other Parts Discussed in Thread: BQ24075 , Hello, I have an application where I might want to use the bq24075T to charge a battery at 190 mA. I noticed that the bq24075T datasheet has a specified minimum of 300 mA (R_ISET = 3 kohm…

  • RE: BQ24075T's Vout

    You are right that when Vin is above Vout + Vdo, Vout will be regulated to 5.5V. If Vin is 5V, Vout = Vin - Iout*Ron. The value depends on the real dropout across the FET. Thanks, Wenjia

  • BQ24075T vout(reg) question

    Other Parts Discussed in Thread: BQ24075T , BQ24073 Dear, Do you know what's the Vout(reg) means as shows below, why BQ24075T 's Vout(reg) is as high as 5.5V? my understanding vout(reg)should equal to 4.2V. is't right? another question is what 's…
