Other Parts Discussed in Thread: BQ2954 , BQ2054 , BQ24600 Hello,
i am currently working at designing a battery charger for charging a 6-Cell LiIon Battery pack (with built-in protection/balancing).
Target charge current is 5A, charge voltage 4…
Hi Andy,
I think that is obvious from the table. Under the TEST CONDITIONS R SENSE =10mΩ. Moreover, it is not needed according to equation 2, 3 and 4 since V ISET is provided.
Thanks,

Part Number: BQ24610 Please place all decoupling capacitors as close as possible to the IC pin they correspond to (following the Layout Guidelines and priorities for each device). However, please make sure that the VREF, VCC, and REGN pins are not loaded…
I plugged the two thermistor values (0C = 27k28 and 40C = 5k827 )from the 103AT datasheet, into the equations and came up with a lower resitor value (R10) of -2M481 ohms (yes that's negative). The upper resistor (R9) came out to 9k945ohm My conclusion…
If you need more details let me know. The project is mainly looking at chargers and BMS circuits that will provide power to a 24 V motor to run a small RC aerial vehicle in combination with another small engine. We need EE gurus who can help us find the…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
