New product announcements are made
nearly every day. I subscribe to many trade journals and each is filled with
hundreds of flashy advertisements. But, only a few of those product ads catch my
eye. Since I’m a circuit designer, I especially like those components that trigger
many new application ideas in my mind. Sometimes it is the smallest products that
are the most useful. Tiny surface mounted components that perform a nice little
function have countless applications. I also like anything that keeps battery power
consumption low. These days you can do many interesting things with a well-designed
circuit powered from just a few tiny button battery cells. |
|
I often discover new products in surplus electronic
catalogs. The surplus companies often buy up stock that came from companies that
went out of business. Bad marketing or bad management may have killed a perfectly
good product idea. Their loss can be your gain if you can spot the bargain. |

In this section I will highlight some components or products
that have attracted my attention. Let me know what new products you have seen that
got you excited. |

Ultra Low Voltage Switching Regulator from TI |
| Finding any IC
that operates at low voltages is rare. Finding a switching regular IC that runs
down to 0.3 volts is therefore really a surprise. The TPS61200 (http://focus.ti.com/lit/ds/symlink/tps61200.pdf)
from Texas Instruments was designed to boost the voltage from single NiMH cells to a
higher voltage. With an operating range that extends down to 0.3v, the device is
perfect for powering something from a single 0.5v solar cell. It has a maximum
average input current of 1.5 amps, which can translate to an output current of 500ma
at 5 volts. I think I might try using this part to design a 4 cell 4.8v AA NiMH
battery charger, powered by a single large solar cell. |

Zero Bias Voltage FETs from Advanced Linear Devices |
| Advanced Linear Device (http://www.aldinc.com/)
has been able to carefully fabricate some N and P channel enhancement mode FETs so
they conduct current, even when the voltage between the gate and source is zero volts.
This feature comes in handy when designing some low voltage amplifiers and
oscillators. I have been able to run a square wave oscillator using two of their
FETs with a supply voltage of only 0.16 volts. |

Tiny Coin Shaped Thermocouple Thermopile Voltage
Generator |
| Thermo Life Corporation (http://www.poweredbythermolife.com/corp.htm)
has developed a coin shaped heat to electricity converter. A 5 degree C
temperature difference from front to back will generate an open voltage of 6 volts and
will feed 10 micoamps of current into a 300K load resistance. With a 10 degree C
difference, the power generated increases to about 100 microwatts. The maximum
operating temperature is 100C. At such a temperature difference, the device should
crank out about 1000uw of power. These devices might be used in energy
harvesting applications where warm objects exist. At 10ua, the device could
charge up a 100uF capacitor in about a minute. The energy stored in the cap
could then be used to power a wireless sensor link, such as Zigbee. |

Linear Magnetic Hall
Effect Rotary Sensor |
|
|
|
|
Melexis (www.melexis.com)
makes some of the best hall sensors on the planet. Their MLX90316 offers
a unique device, which exports a voltage proportional to the angle of rotation of a
nearby magnet, as shown below. This function might come in handy for some human
interfaces where a knob can adjust the volume of an audio signal or some other
variable with no physical contact with the device.

Super Small Memory
Cards From SanDisk |
|
SanDisk (www.sandisk.com)
is now offering a tiny flash memory card with storage up to 4GB. Their “Micro
SD” cards shown below measure just 0.6” x 0.4.” These incredibly small memory
cards will find their way into all kinds of applications, which require a compact
method to store data. A 4GB card can store about 1000 MP3 songs. |

Monolithic Schottky
Bridge Rectifiers From Central Semiconductor Corp. |
 |
Many power supplies take advantage of the lower voltage
drop of a schottky diode to improve overall efficiency. However, usually four
separate diodes have to be used to form a full bridge rectifier circuit. Central
Semiconductor (www.centralsemi.com)
has now made things easier by packing four schottky diode inside a monolithic surface
mounted bridge rectifier. The small 1 amp rated device saves circuit board real
estate and reduces the total parts count, which can translate into cost savings.

Digital Pots from
Micro Bridge Replaces Mechanical Pot |
|
Often a mechanical potentiometer is used to calibrate a
circuit, set the gain of an amplifier or null a voltage offset. These can often
become contaminated or broken. Micro Bridge Technology (www.microbridgetech.com)
has solved this problem by offering a digital “rejustor” device, which can perform the
same function as a mechanical device. |
|
|
|
Tiny
Piezoelectric Motors from New Scale Technologies |
 |
These incredibly tiny motors are driven by a small
piezoelectric element, which rotates a tiny treaded lead screw. New Scale’s (www.squigglemotors.com)
squiggle motors are being used to move small devices, such as auto focus lenses and
micro fluid pumps, with great precision. |

Ultra Low Power Crystal
Oscillator IC from EM Microelectronic |
|
When trying to squeeze every last joule of energy from a
circuit, even the power required by a crystal oscillator can be important. EM
Microelectronic (www.emmicroelectronic.com)
has solved this problem with their EM7604 crystal oscillator control IC, This
device draws only 0.25 microamps, when used with a standard 32.768KHz watch crystal.
The IC operates from 1.2v to 5.5v and over a temperature range of -40C to 125C.
Internal integrated oscillator capacitors keep the part count to a minimum. You
only have to connect a crystal. |

Full Featured Digital
AC Wattmeter from Electronic Educational Devices |
|
|
Electronic Educational Devices (www.wattsupmeters.com)
has developed a great digital wattmeter. This device is similar to but better
than, the very popular “Watts Out” AC power meter. You simply plug the device into an
AC wall outlet, then plug the AC load you wish to monitor into the device. This
neat device has more features than you can shake a stick at, including the ability to
record the power line data to a computer, through its USB connection. PC
software is included with the device. |
