LTC4010 for NiMH battery charger application. There are some field failures: CHRG indicators ON, FAULT off, no PWW, no charger current. VTEM 10k to GND.
Thanks for running the test. Looks like there are some transients but those voltages should not damage the part. Why don't you contact me privately at email@example.com so we can…
The LTC4010 does not have a reference design, but the very similar LTC4011 does and you can use that for a reference for this part selection:
This is not enough information to tell if the circuit is damaged or if something else is wrong. I recommend that you check the requirements for charging (battery voltage, for example) and refer to the abs max limits in the datasheet. If you think the circuit may be damaged, perhaps try probing around and replacing parts that don't seem to be working.
just need small favor, do you have a ref sch for this part with bom? or can you suggest basic notes to select the right power transistors? especially Ciss, Coss, Qg, Qgd, etc. thank you. Fausto bartra
