.. Figure 5. 2.2 amp-hour lithium-ion battery. Figure 6. 4.9 amp-hour lithium-ion battery. Version 2 Jim Wilber looked at my design for a battery charger and sent me some suggested changes. He suggested using the LTC4412 ideal diode IC to ...
.. input is grounded. A detailed description of a loop current converter with governing equations can be found in my earlier Design Idea “A 0-20 mA source current to 4-20 mA loop current converter” ( Ref. 1 ). As a bonus, this ...
.. linearized output is a useful elaboration of a capacitive sensor design. But what if the circuit is located a significant distance from the control electronics? Recently, Design ...
.. circuit also ratios sensor capacitance to a reference capacitor to measure micrometers this time linearly. A few weeks ago, Design Ideas published a simple circuit of mine that provides an analog interface to capacitive position sensors ( ...
.. pair to drive not just two but three LEDs. As everyone knows, rainbows always have pots of gold at their ends. This Design Idea reverses that, starting with a pot (no gold, alas) and ending with a rainbow. Bi-color LEDs can be ...
.. like TO220 packaged power pass transistors sporting substantial heatsinks. Would Greta T. approve? I think not!7 The design in Figure 1 offers a cool (and maybe even useful) efficiency improvement. It thriftily recycles most of the 4 ...
.. V REF input of Z1. The principle in play is discussed here ( Ref. 1 ). A potentially annoying shortcoming of the Figure 1 design, however, is its current sink output that’s referred not to ground but to the V+ source node, which ...
