Part Number: BQ24640 Trying to determine why the charger will not hold the charge at the set point
This is a brand new design. When powered on, the charger would charge to the setpoint of 23.4V and shut off. The load would slowly dissipate under a light…
Part Number: BQ24640 Other Parts Discussed in Thread: BQ24610 Hi,
I wish to know the difference between the BQ24640, which is a charger particularly for the super-cap and other normal chargers. Does BQ24640 have any special function?
Best Regards

Hi Mike,
thank you. I understand. This makes sense. I will build this up and perform more Tests.
I have another task:
To increase the lifetime of the SuperCaps i want to implement with the BQ24640 a variable charged voltage for the SuperCaps. So if the…
Part Number: BQ24640 Hi Team,
My customer wants to design a super capacitor solution in their automotive T-BOX(TCU) application.
Their requirement is when the T-BOX is power-off, T-BOX still can work for 5s-30s. The holding time is only 5-30s, so they…
