lm66200 ideal diode makes hot swapping supplies 💡🔋🔌📱📌👍🤔⚠️
most projects these days have multiple power supplies: say a battery or DC wall plug or USB for multiple powering options. juggling these to have seamless hot-swap while avoiding backpowering is always a bit of a challenge: you want to keep things small, cheap, low power and of course reduce as much voltage drop as possible. the LM66200 (https://www.digikey.com/en/products/detail/texas-instruments/LM66200DRLR/15856663) is a cute solution to dual supplies: it has back-voltage protection, and two 'ideal' diodes with RdsOn of 40 milliohms, 2.5A continuous draw and a separate enable input and status output. only downside? the max voltage is 5.5V - what we'd love is a version that goes up to 12V!
It’s important to test the power output of your USB hubs. This will often explain why certain peripherals are having problems. . . #sysadmin #sysadminlife #helpdesk #itdirector #testit #usbpower #skhlaw (at Stahancyk, Kent & Hook) https://www.instagram.com/p/CeonbE0J7pD/?igshid=NGJjMDIxMWI=

He impreso la primera versión del molde para la fuente de corriente USB con interruptor y led indicador. La idea es tener un bloque que permita alimentar con 5v varios proyectos con un interruptor que corte la corriente al apagarlo.
Quiero meter en un bloque de resina epoxy transparente todo el montaje, pero para empezar habrá que impermeabilizar el interruptor, que no está diseñado estanco!
