Tristar U2 Charging IC Compatible For iPhone SE (2016) / 6S / 6S Plus / IPad Air 1 / Air 2 / Mini 4 / Pro 9.7 (U4500: 1610A3)
This chip is the tristar you're looking for almost all the time.
It is a myth that you need to replace iPhone 5s tristar A1610A1 with A1610A1 etc. We have tried it---THIS TRISTAR is compatible as a replacement for ANY 1610 tristar chip. You can use it for iPhone 5s, 5c, SE, 6, 6p, 6s, 6sp, 7, 7p, and even iPad Air 1, 2, iPad mini retina, etc.
It is better for you to memorize what devices do NOT use this 610A3B tristar--do NOT use this one for:
iPhone 5, iPad 4, and iPad mini original---they all need the 1608 tristar chip.
iPhone 8 and beyond don't use tristar at all, they need hydra.
