Part Number: EMB1499Q Other Parts Discussed in Thread: EMB1428Q hi,
Previous problems remain unresolved,EMB1499Q can charge, but can't discharge.
Pretty sure it's not a software problem, EMB1499Q only need two control signals, EN and DIR, no other…
Part Number: EMB1499QEMB1499Q: emb1499Q can be charged, but not discharged - Power management forum - Power management - TI E2E support forums
I have exactly the same problem but don't know how to deal with it and ask for support. Thank you! The scheme…
Part Number: EMB1499Q Other Parts Discussed in Thread: BQ76PL455A hi:
We designed a board with emb1499Q,it can charge,but can't discharge。
We've added a load gauge to the external electronics to ensure we can consume the discharge energy.
when open…
Part Number: EMB1499Q Hi experts:
I observed high amplitude parasitic oscillator in switching node of EMB1499Q DC/DC circuit. Say the drain node of primary side active clamp PMOSFET, and the drain mode of secondary side synchronous rectifier MOSFET. That…
Hi Chime,
I think the manner in which you debugged the first issue may be the best path forward since we dont have the details of your design. Can you double check your commands are correct as well?

Part Number: EMB1499Q Other Parts Discussed in Thread: EMB1428Q , BQ76PL455A , BQ79616 Dear Sir/ Madam,
can we use EMB1499Q & EMB1428Q with LTO battery balancing which voltage range 1.5V to 2.9V & 10A balancing current?
Please reply as soon as …
Part Number: EMB1499Q When the EN pin is pulled high, done goes low, but there is no signal output for gate _ LS and PWN _ clamp.
The measured DIR is high and DIR _ RT is low.
Experts are invited to give guidance.
Thanks!

Part Number: EMB1499Q Other Parts Discussed in Thread: BQ79616 There are two points for EMB1499Q:
1.TM pin is the test mode selection pin, but I do not know whether it is high level to enter the test mode or floating?
2.How are primary current limit faults…
Part Number: EMB1499Q 1499Q mentioned in the Datasheet is the current control, I do not understand how the output voltage control? What is the output voltage on the secondary side when the wire is disconnected while charging a single battery? The red circle…
Part Number: EMB1499Q In some applications we have problems in charge mode, because the wire adds up to 1.5 volt to the cell voltage, even with a 2-3A only. It is not possible to make a better connection. The internal circuit of 1499q properly stops charging…
