There is LTspice model for LTC4020 that can be downloaded from site.
I'm designing a device which will be employed in cars and trucks, so it must withstand 12V o 30V as an input (battery of the vehicle). Additionally, 4s Li-ion (16.2V) will be placed in our devices as a back-up battery since if he vehicle is turn off,…
I would like to ask if the components in D5, D6, D7, and M1 in DC2044A can be omitted. I just want to use LTC4020 for lead-acid charging. In the back I will add a battery and switching power supply to switch LTC4418 to switch. .
No. I have blown up several LTC4020's by connecting the battery backwards.
I cannot find the order information for the LTC4020 there are two types:
LTC4020 EUHF and LTC4020 IUHF in the manual I can find this URL ((http://www.linear.com/product/LTC4020#orderinfo) but there is no explanation about the order code.…
Your settings and modification look good: lead-acid, and change of R10 value to set absorption voltage to 28.8V.
I performed 2 measurements of the unmodified DC2134A as follows.
For the first test (VR10 = 2.1231V), the voltage at VFB is below 2.3125V…
Hello, I am doing a charging project with LTC4020. I would like to ask how the feedback loop of ITH and CSOUT feet of LTC4020 is calculated. I see very few descriptions in the specifications. There are also different results in LT spices simulation because…
There is an LTspice model for LTC4020, so that can be simulated. LTC4162 does not have a model.
I am designing electrical circuit for charger.
I use LTC4020 as charger controller.
I envision a way for the user to remove the battery pack from the charger and reconnect it.
Battery pack has thermistor.
LTC4020's NTC terminal is open when battery pack…
