I would use INA228 to detect LED lightbar turn-off current.
Maybe 10uA or 1uA.
i will put a Rshunt(10 Ohm) on the low side or hight side.
Excuse me.
Can TI provide the sample component for TINA?
THX.
您好,您是想在TINA中找10uA或1uA电流源用于仿真是吗?
点击TINA中的source,其中这个图标就是电流源。
明白了,但是INA28没有可用于TINA的宏文件,或者说通常来说,我们没有数字输出的TINA spice model用于仿真呢。
