Many integrated circuits have undocumented features or abilities. This is one of them. The TLC555 output (pin 3) can sink a 100mA load to 1.28V. The open drain transistor reset (pin 7) can sink 100mA ...

Single-coil latching relays find use in signal-routing, audio, and automotive systems. To maximize their usefulness and cut power consumption, these coil currents must flow in both directions. Current ...

Efficiency is the name of the game in power-system design, driven by the need to better leverage available energy and deliver more power from a smaller package. Except in some specialized or extremely ...
