My request: 0 parts. Bonase Electronics HK Co. Part Number:. A lead acid battery is similar to a LiPo. It requires CC charging as the battery voltage rise until it hits the float charge voltage and only at that point the voltage becomes constant. Essentially you have a fix voltage regulator with a current limit.

The output voltage is limited by the current limit during CC stage and that the output voltage is below the voltage setting. If you share the control circuit with the power supply for charging, you cannot depend on your supply rail as a reference. Are you sure you understood the idea? A 5 Volt regulator for the deals with the voltage instability and allows you to switch at predictable points. It would be very difficult to make your circuit adjust both the charge and cut-off points independently by temperature, or to trim their values afterwards.

Why would you let a PbA battery deep discharge like that before charging it? In parallel, the figure also shows the recommended float charge voltage to which the charger reverts when the battery is fully charged.

Also, why are we still using thick film resistors? Nowadays, we should only rely on using hydrogen sulfide for conducting electricity. My comment was hyperbole or reductio ad absurdum. Instead, there can be uses for both, even in new designs. When I typed that original comment, I put at the end, but the filter decided it was an html tag and had to go. I remember when the was new. It got publicity, but so did many other ICs. It was a time of growth, companies wanting that next successful IC.

Some were intriguing, some were successful. The Norton amplifier came along in the LM, seemed to have great potential, but too. The LM came along complete with a large datasheet full of uses, and while it lasted a long time, never saw the use that one would expect from the launch. Others had too limited use. Lots of radio-related ICs, few lasted long, and not even the ones for consumer radios.

And yet, a simple AM radio IC, the ZN and its descendents, has been around for 45 years, neat toys for hobbyists, but I never saw much commercial use, except in recent times. The was refined, a CMOS version that never won over.

There were quad variants, the and , same principle but fewer pins, hence not as versatile. The mistake may be that tubes went through iterations, so why would an IC last fifty years?

But they improved dramatically, and got smaller. Chip that old are made in older fabs on much larger geometry. The cost per chip can be much cheaper on smaller geometry. One day, they might be EOL.

Chips were probably designed before modern day chip design tools, but is simple enough to be redesign from scratch. Maybe the distributors keep them in stock just for me, but I doubt it.

I feel like Rip Van Winkle. Must have skipped a few years ;. The original Apple II joystick interface is a dual timer. Joystick X and Y pots vary pulse widths, which are timed by software. Both iconic works of hardware genius. I prefer the PIC and the Attiny, because a lot of projects can make pretty good use of the added capabilities Do you really want a blinking light, or would you prefer three fast blinks with a long space? Microcontrollers give you that choice. People do so much with these little chips.

We currently manufacture and sell stir plates with a speed controller based on a timer. The end result would have been higher manufacturing cost. I just looked up timers on Digikey and items, including dual and quad variants returned against that query. The right solution is often the lowest cost reliable solution for the job and sometimes the answer is a timer. Just because the part is older than you are does not mean it should be over looked in product design.

Flash roms have data retention times around 10 — 20 years — an analog chip will just keep chugging along. Unless you were shooting for some ridiculously low frequencies with the , why would you use an electrolytic? It can be used for other things like time delays. Datasheet say that the upper limit of R is about 5M, so if you need a longer delay than 5 seconds or so, you would need a cap larger than 1uF.

The time delay for the heating element in my food saver would be one place that this kind of delay is needed. Special Films for ID documents enable security features to be integrated.
