BQ28Z610: Manufacturer Date
Part Number:BQ28Z610
Hi,
I've been trying to read the Manufacturer date of this fuel gauge. Based on SLUUA65C, ManufacturerDate() value in the following format:Day + Month*32 + (Year–1980) * 512 with the default value of 01/01/80 but the register returns an unsigned integer value from 0 to 65536. I'm trying to read this data via I2C line between the fuel gauge and an MCU. I am not certain how to go about the calculations. Are there any more notes on this? The technical reference doesn't have much guide with fuel gauge communication via MCU.
Thanks,
Kat

BQ25890: D+ D- connect
Part Number:BQ25890
Hi,
my customer uses BQ25890 D+ D- (CHARGE_USB_DM & CHARGE_USB_DP shown below) to communicate with the USB adaptor for high voltage handshake.
And the MCU also need to communicate with the USB adaptor.
So they wonder if it's okay to connect D+ D- of adaptor to both BQ25890 and the MCU through 0ohm resistor.
Do they need a USB switch to switch between MCU and BQ25890?

TPS61030: recommendation resistor value for pull up or pull down LBI pin
Part Number:TPS61030
Dear team,
If I do not need use LBI function, what resistor value (R1 or R2) should I use for pull up or pull down LBI pin? Or I should just connect LBI pin to Gnd or Vcc directly without resistor?
Thank you.

BQ25504: Compatibility of a 4.15 OCV solar panel
Part Number:BQ25504
Hi All,
I was just wondering whether using a 4.15 OCV solar panel for BQ25504 chip would cause any issues?.
Even though datasheet mentions an absolute maximum of 5.5V on the VIN_DC pin, can the chip still be be able to operate with MPPT at 3.35V of the solar panel.
The datasheet of the solar panel is as follows. It would be really great if I could know an answer ASAP.

Sanchitha.

BQ25895: Vsys shut down when disable charge without battery connected
Part Number:BQ25895
Hi, my customer is testing with no battery.
The schematic is as below, 5V connected to VBUS.
The registers read before the action "disable charge by setting REG03[4]=0" is as below:
Reg[0x00] = 0x7f
Reg[0x01] = 0x06
Reg[0x02] = 0xfd
Reg[0x03] = 0x1e
Reg[0x04] = 0x18
Reg[0x05] = 0x11
Reg[0x06] = 0x4f
Reg[0x07] = 0x85
Reg[0x08] = 0x50
Reg[0x09] = 0x44
Reg[0x0a] = 0x93
Reg[0x0b] = 0x76
Reg[0x0c] = 0x00
Reg[0x0d] = 0x92
Reg[0x0e] = 0x53
Reg[0x0f] = 0x53
Reg[0x10] = 0x3f
Reg[0x11] = 0x98
Reg[0x12] = 0x00
Reg[0x13] = 0x3f
Reg[0x14] = 0x39
Then we disable charge by setting REG03[4]=0, Vsys go to 0.
1. What may cause Vsys shut down?
2. Why capacitor is needed between VBAT to GND? And how to determine the value?

Hi,
Do TI has drivers for SMBus, for the host.
I mean, instead of addressing the specific register to get, for example, a battery capacity, just write some order in the program ...

TINA/Spice/UCC28070: UCC28070 question about TINA-TI Transient Reference Design（slum328).
Part Number:UCC28070
Tool/software:TINA-TI or Spice Models
Dear support member,
My customer used UCC28070.
I have a question about UCC28070TINA-TI Transient Reference Design（slum328).
In this circuit model, the output current is 0.75A (max).
I want to simulate as 7A under the specification conditions.
(Question)
Where should I change when operating with a load of 7 A as a UCC28070 simulation circuit(slum328)?
Best regard.
Bob Lee.

SPRABW0C
Dear TI team
Refer SPRABW0C application note , Please advise what is full bridge control type ( general full bridge or phase-shifted) ?
Is this possible if use controller IC instead MCU control(please suggest feasible part)?
Our team need to design 12Vdc input /380Vdc output ( Power range 500W-1kW)
Based on SPRABW0C suitible for above requirement or not?
Also please advise SPRABW0C magnetic spec for reference (i.e.Transformer turn ration Np,Ns Lp Lo)
Can we use UC2827-1 for full bridge topology(voltage or current fed)?
Best regards

LM5017: isolated 15V DCDC PWR supply
Part Number:LM5017
Hello,
my customer is currently designing an isolated PWR supply for their gate driver and is looking at using the LM5017 for this.
Here are the specifications of their 15V DCDC:
Vin: 16 – 30Vdc
Vout min = 16.5V (to be used with a low cost LDO to get a stable 15V)
Vout max: around 20V to limit losses in LDO
I out: 0.3A max
To do some quick testing, they mounted their transformer (i prefer to send share the transformer details offline) on the EVM AN-2204.
They got an output voltage by connecting in serial both secondary windings of the transformer.
Because they are not comfortable with their first test, They would like to ask you if you could have a look and confirm that it is possible to reach their specifications with this LM5017 and their transformer.
Or if it is preferable to use another dedicated transformer.
thanks for you support.
Regards,
Stani
