Hi, Support Team

Could you tell me the dead time of LTC4013? (Min/Max of the design value)

I would like to use it as a calculation when selecting a FET.

Thank you for your help.

Good day,

          We are desing 36v vin to 28.7v 7cell li-ion battery charger with LTC4013. We use one  DC load to simulate the batterey to test, but the SW just output 0v. INTVCC =5v, seems no calculation faults with external RC. Can you help to advice

Hi

I have a question LTC4013.

1. Regarding maximum charge current control
Understanding that it is determined by Rsense, is there any other means to control charging current (maximum)?


2. Regarding gate voltage of half bridge (MOSFET)
Is it 5V drive…

Hello! I want to use the LTC4013 chip to charge the LiTiO battery. I need to charge with a voltage of 2.8 V. I want to charge in 2 stages. First, direct current, and then constant voltage.
As I understand it, I can regulate the maximum charging voltage…

I've designed a charger that's 28-32Vdc In for a 24V battery that charges at 10A. Schematic is attached.

In the bulk and absorption phase the SW pin appears to be oscillating, similar to that of an unstable buck. I've played around with the…

1. Datasheet says "However, during start-up and recovery conditions, the gate drive signals may be as low as 3V. Therefore, to ensure that the LTC4013 operates properly, use logic level threshold MOSFETs with a VT of about 2V or less"
We have…

I've designed a board and am waiting for it to come in, but I was wondering if I use the diode resistor combo as seen in Figure 16, will I then be able to draw current from the battery terminal with an electronic load? I'd like to do testing without a…

Li-ion charger modeled after schematic on datasheet page 35. 

Design specs 

DCIN 22 - 24V

Vbat 12.3V

Max charge current 20A.

How it works

With the battery at 6.3V, DCIN = 24V/3A from bench supply, Green LED comes on

INTVcc = 5.01V

FB = 1.42V

Hi,

We are looking for the LTspice model of LTC4013. According to the previous Q&A about LTC4013, there's no model available before. Are there any updates? Thank you for the advice.

Hi All,

The LTC4013 has "E" and "I" versions. What is the difference between them?

The price of I version is higher than that of E version, the I version is for an automotive market?
