As per defaults above for 12V SLA battery, please advice if Vin need to be above Vequalize for charging to function properly.
For the demo board of DC2038A-Q, we could not get to normal charging mode when Vin at 14.xV & 15V.
We only can get normal…
We have a prototype board without an NTC. I would like to disable temperature compensation, but writing register 0x29 (en_sla_temp_comp) to 0 does not seem to work. Reading the register returns 0x02 (which I understand is 1, offset 1 as per the datasheet…
Hi,
I am using 24V lead acid battery charger LTC4162IUFD-SST#TRPBF fixed volatge version and 100% working fine.
But SST fixed voltage version is not available now, So im testing with LTC4162IUFD-SADM#TRPBF I2c adjustable version, Battery charge is terminated…
In the case of no input power supply, the battery is 26V, will it cause the GS breakdown of the mosfet? Is there a design problem with the DC2038?
Hi, I want to use the LTC4162EUFT-SAD in a new design. It cant be got at the moment. I was wondering if we can use the LTC4162EUFT-SADM instead and set MPPT_EN to off, as we dont need it. Is there anything else different in this version that I have missed…
I want to use one I2C bus to control until 4 ic's LTC4162-S. I was thinking in use a I2C hub ic or control the i2c lines of each ltc4162-s with mosfet or analog switch. However, I think I can use the DVCC pin as enable for the communication, this means…
Siglo,
Sorry for the long pause, had some other items and now getting back to this. In my testing, it appears if the 12V battery is not depleted very far (11V), our circuit will re-change, but if deeply depleted (<10V), it does not properly go into constant…
If we power up our system with battery installed and then remove the battery we cannot seem to detect missing battery. It appears to remain within the cc_cv_charge state. The battery voltage continues to measure 6.5 volts. There is a 10uF cap hanging…
I am planning to use the IC as a standalone charger without use the powerpath. So I was wondering if I can remove the powerpath components (infet, batfet, r_sense) in order to make a more simple design and save extra costs. If it is possible, Could you…
Could you please explain why connecting a 470k resistor from Vbatt (24v) to RT pin (which is using a 63.4k resistor to ground) will disable the charger?
