Could you please help identify these two components? It is a circuit for low voltage battery protection cutoff.

  1. First pic, this black box it is located between Vin somewhere i cannot figure out (the trace shown in 3rd image) . and i donot know how many pins it has

    enter image description here

  2. Second pic, these 2 ICs are the same SOT-23-6 (I think). Named 0266J or 0265J or 02S6J. they are located near a MSP430 microcontroller.

    enter image description here

EDIT: I have uploaded a third pic to show the black box from the side maybe it will give a clue about its height and pins ?!

  • How many pins does the 'black box' have, and what are they connected to? – Bruce Abbott Jun 03 '22 at 20:40
  • @BruceAbbott , i have edited the question – ElectronS Jun 03 '22 at 20:57
  • this is a 4layer board thats why i cannot flow the where the via is going . but right side in pic3 or left side in pic 1 is certainly connected to Vin. my intuition says it is a snubber Resistor or capacitor maybe ?? – ElectronS Jun 03 '22 at 20:59

    Too many connections to be a capacitor. Perhaps a relay? – Bruce Abbott Jun 03 '22 at 21:29
  • @VoltageSpike i tried using DMM in resistance mode it showed more than 2.5Mega ohm . and in capacitance mode nothing . – ElectronS Jun 04 '22 at 12:21
  • @BruceAbbott the problem is that the pins are hidden under neath so i donot even know how many pins it has . i am thinking about using hot air to remove it – ElectronS Jun 04 '22 at 12:22
  • @VoltageSpike length : 12mm . width 6mm at base 4mm at top . height is 7mm – ElectronS Jun 04 '22 at 12:25

I think your black box may be a low signal relay from Omron. Check this datasheet out. It has the A2 and the C5BY as part of the part#.

For the ICs, I think they may be TI's TLV62569 or TLV62568 buck converters. Here's the datasheet for both of them. There is also a chance (probably unlikely) that the ICs are New Japan Radio's NJM2561 but I can't give a good answer unless I know what the circuit was a part of. Hope this helps!

    The Omron G6A is only available in through hole packages so I'd expect this is something else [see here for the omron LSR lineup](https://components.omron.com/us-en/products/relays/signal-relays/signal-relays) – soup Jun 13 '22 at 16:11
  • the black box looks like it has only 2 connections , so probably not a relay . the other ics are 100% not buck converters they are connected to microcontroller . they might be voltage reference . but thanks for trying to help :) – ElectronS Jun 15 '22 at 20:47
