Searching for a 8*7135 driver with temp sensor and free pin 5 or 6

Hi all
I want to build a headlamp using a "of the shelf" driver and burning my own FW so I am searching for a driver with these features:


1. Internal temperature senor (for my understanding Attiny25/85)

2. Option to connect to one of the PWM pins without soldering directly to the MCU so I will still be able to program it using a clip for example star 2 in Najang 105c.


The reason for "2" is to connect 8*7135 slave board for a 2nd LED and control it using the free PWM pin.

If you know a source for a 8*7135 slave board it is also helpful.

Cheers

External temperature sensor is also possible but I don't know if there are commercial drivers using external sensor

If your writing your own FW, couldn’t you replace the attiny13 with a 85 to gain the mcu internal temp. I have replaced the 13 to a 85 several times with the blf a6 17dd fet+1 driver to be able to run NarsilM. The fet+1 drivers that most of these FW’s use here was born from the 105C driver. Comfychair got the bright idea of taking a 105C driver and replacing one of the amc7135’s with a fet and that started this whole new fet+1 driver world. Im not a expert at FW’s, but I wouldn’t think there would be to much difference between the two drivers as far as writing code to make it work with the 105C.
.
Maybe you could use this driver and instead of controlling the fet on the board, remove it and use the appropraite fet pad to control the slave board.

Thanks moderator007,
I had a lot of trouble finding soic8 Attiny 85 to replace the 13, where do you buy it from?

The H17Fx is a good option although It is a bit more expensive than the 105c, I was hoping to find a budget driver :)

TA17? Texas Avenger "TA" Driver series - Triple channel + Bistro or Narsil + Clicky or E-switch - The Ultimate open source driver!

You do have to bend the legs in to fit the original pads, not hard to do at all.
I purchased mine from Arrow but I think Digikey has them also. Arrow’s free overnight shipping was a pretty sweet deal while it lasted.

I think Lexel still sales the TA17 that e1000 linked above. He could probably answer any question you might have.

Thank you all, I will check the TA17

As mentioned above, the 85 can be made to fit 13a footprint by bending it’s legs. Here are a few images from my earlier drivers where I was using a 85 with bent legs on a smaller footprint.
