The LM73100 is a cute ideal diode 😎🔋

As we pass through the cycle of life, some may seek ideal happiness - we can't help with that quest. But if you're looking for an ideal diode, we found a pretty sweet one on last week's The Great Search: 🔍 https://blog.adafruit.com/2025/05/05/the-great-search-power-monitor-with-2-inputs-thegreatsearch-digikey-digikey-adafruit-2/

The LM73100 🔗 https://www.digikey.com/en/products/detail/texas-instruments/LM73100RPWR/13627234 … can handle up to 5A and 23V - perfect for applications like solar panels where you want to avoid losing 0.5W+ to a Schottky diode.

Here's a quick breakout we designed for it: By default, it works just like a diode, with VIN and VOUT terminal blocks. But if you want to access more features, there's a 0.1" breakout. The IMON pin gives a voltage from 0-1.5V as current goes from 0-5A. Plus, it has options for overvoltage and undervoltage lockout and a power good output. ☀️🔋
