I want to build NiMH/NiCd battery charger for 3 cells series connected. I found LTC4060 but it allows fast charging only. My battery pack of NiCd batteries is 3.6V/800mAh. I want to charge it with 80 mA current, but I have read that –∆V termination…
Is it possible to design an LTC4060 2 layer board for a charge application with power path? This will be providing power to a couple other microcontrollers where the ground plane on the bottom might be broken up by some signal paths from the micro's.…
I have trying to use LTC4060 as a charger IC in my design. I have made the design based on the datasheet's application diagram, using it to charge 4-cell Ni-MH battery pack. Found some issues listed below
1]Pass transistor (MJD210) used is getting…
we would like to use the LTC4060 to charge a 3 cells NiMH battery pack. The capacity of the pack is 12000mAh. My question is if the LT4060 can be used to charge this pack with 2A. I thought about maybe reseting the timer every 3 hours by toggling…
I need your help and not sure if this possible, I came up with a schematic for backup power for our new product that uses LTC4060 (battery charger), LTC3124 (boost), and LTC4415 (Oring). Would it be possible to share this with your team to get…
The /CHRG and /ACP pins are high-Z when the LTC4060 is not powered. Applying voltage to them (like through the pull-ups as you mentioned) will not power the part.
I have implemented the battery charger described hereunder:
The transistor is a MJD210.
However charge never begins...
I have measured the following parameters:
Vusb = 5.1V
Vntc = 3.4V
Vbat = 2.2V
The ACP led is lit, but not the charging LED…
Hi trying to design a handheld device powered by 2 NiMH cells in series. And USB is required to charge the 2 NiMH cells when connected.
Is the LTC4060 the best option?
And I’m most likely will not put a thermistor in the design, does the LTC4060 work…
We measured current at output of the battery (we placed a current meter between the battery and the charger LTC4060). The LTC3124 has two 22uF caps placed at output (not shown in the previous schematic),
LTC4011 will unfortunately not work for 3 cells at 5V: DCIN(MIN) = (n • 2V) + 0.3V [where n is the number of series cells]
LTC4060 may be a good fit here.
