11.HIGH EFFICIENCY

DESCRIPTION
The I.C. is a full bridge driver for motor control applications realized in Multipower-BCD
technology which combines isolated DMOS power transistors with CMOS and Bipolar circuits
on the same chip.

By using mixed technology it has been possible to optimize the logic circuitry and the
power stage to achieve the best possible performance. The DMOS output transistors can
operate at supply voltages up to 42V and efficiently at high switching speeds. All the
logic inputs are TTL, CMOS and mC compatible. Each channel (half-bridge) of the device is
controlled by a separate logic input, while a common enable controls both channels.
The I.C. is mounted in three different packages.

Describe and characteristics about ic components LMC568 details

The electronic components LMC568 is an amplitude-linear phase-locked loop consisting of a linear
VCO, fully balanced phase detectors, and a carrier detect output. LMCMOS™ technology is employed for
high performance with low power consumption.

The VCO has a linearized control range of ±30% to allow demodulation of FM and FSK signals. Carrier
detect is indicated when the PLL is locked to an input signal greater than 26 mVrms. electronic component LMC568 applications include FM SCA and TV second audio program decoders, FSK data demodulators,and voice pagers.

Features

1.Demodulates ±15% deviation FM/FSK signals

2.Carrier Detect Output with hysteresis

3.Operation to 500 kHz input frequency

4.Low THD—0.5% typ. for ±10% deviation

5.2V to 9V supply voltage range

6.Low supply current drain

Japanese firms to China to seek electronic components supply chain

Japan after the earthquake struck, many electronic component manufacturer was different  degree of loss, to a certain extent, will affect China's electronic components supply, 
April 8 to 10 held at shenzhen convention &exhibition center of the first session of the  Chinese electronics show 77, virtually (CEF) made a diversified electronics device supply  and demand for electrical components in China market chain offers more channels, and also  reduces the earthquake in Japan to the impact of electronic components industry.

As is known to all, Japanese chip, flash of electronic components such as consumer  electronics field in the global supply chain from the earthquake, the share great has been  so far, exactly, Toshiba, SONY news says the semiconductor manufacturers believed,  damaged, or stop production factory announced over a period of time cease, and future  global part in electronic components appear tight supply is already industry consensus.

Hqew.net provide ic components UCB1400 and other hot model

The electronic components UCB1400 is a stereo audio codec equipped with touch screen and power
management interfaces.

 It integrates an AC ’97 Rev. 2.1 interface for communication
to an AC link host controller such as the Intel Xscale™ processor. The stereo audio
codec inputs connect directly to a microphone or line level sources such as a CD
player. The stereo audio codec outputs at line level and can drive a headphone
directly. The touch screen interface connects directly to a 4-wire resistive touch
screen. A built-in 10-bit analog-to-digital converter provides readout of touch screen
and power management parameters.

 Ten general-purpose I/O pins provide
programmable inputs and/or outputs to the system.

Hqew.net provide you with the national electronic component UCB1400BE original spot information, price  reference, free PDF download Datasheet material and other hot ic components  lm358,lm317,ne555,lm324 and lm339.
