Other Parts Discussed in Thread: UC3906 , BQ24105 , BQ24450 I made 5 prototypes with uc3906 for battery chargers and then after about 3 months, had problem with uc3906, this chip is burned in 3 times. I ask if this problem is common. I attachment my schematic…
Other Parts Discussed in Thread: UC3906 Dear all
I am looking for advice on using the UC3906 battery charger IC. I have an application using this device to charge a pair of 12V batterries wired in series to give 24V DC. Power supply is from a SMPSU.
The…
Other Parts Discussed in Thread: UC3906 Dear all
Application: A 24V battery-powered controller that runs 1 or 2 6A-rated motors with PWM feedback. A mains charger is used to top-up the batteries, controlled by the UC3906 IC, which is mounted on a small…
I have made charger with use 3906. one charger is ok ( power led and fload led active in start) but others leds fault (power and chargin led active in start). Both charger carts is twin (design and elements). what is problem?
Other Parts Discussed in Thread: UC3906 , BQ24450 Hi,
I want learn about uc3906 dual charger, Re resistor value calculation or its value at Fig.4 in datasheet.
Thank you very much
Other Parts Discussed in Thread: UC3906 , BQ24450 I am buildinga circuit for charging of my 12 V sealed lead acid battery using UC3906. The circuit behaves differently than it is described in the datasheet. It is said in slua115.pdf (U-104 application note…
I have read the aplication note U-104 and in Figure 13 is used as the minimum input voltage of 9 volts for Voc = 7.5 V. my question is, what should be my minimum supply voltage for my charger with Voc = 29V?
thanks for your help
best regards
Other Parts Discussed in Thread: UC3906 , UC2906 , BQ24450 Hello,
I am having issues with getting the pass transistors to turn on when using the UC2906/UC3906. My input supply is set at 24V and I am attempting to charge a Sealed Lead Acid battery(12V batter…
Other Parts Discussed in Thread: UC3906 I have build float dual charger using Uc3906. Results is very good. But I have a problem. battery voltage is reached from 23.5 to 27.5 Volt aproximately 4-5 hours; on the other, hand , reached for from 27,5 to 28…
