SA868

The SA868 is designed as domestic appliance motor controller IC which is specifically for pulse width modulation (PWM) control of motors used in household goods such as washing machines, food processors and drills. The SA868 allows selection of sixteen separate factory programmed rotational speeds with smooth, preselectable acceleration and deceleration in between and externally programmable direction.

SA868 has ten features. The first one is mixed signal technology allows single chip solution. The second one is specifically designed for control of domestic appliances and waveform generation. The third one is built-in high current drivers suitable for direct drive of opto-isolators. The fourth one is selectable carrier frequency up to 24KHz to alow slient operation. The fifth one is wide power frequency range is from 0 to 4000Hz. The sixth one is all user defined parameters held in factory programmed ROM. The seventh one is double edged regular sampling. The eighth one is selectable minimum pulse width and underlap times. The ninth one is selectable acceleration and deceleration times via external resistors. The tenth one is three selectable power waveforms held in internal ROM, including deadbanding technique for reduced losses. That are all the main features.

Some absolute maximum ratings of SA868 have been concluded into several points as follow. The first one is about its supply voltage which would be 7V. The second one is about its voltage on any pin which would be from Vss-0.3V to Vdd+0.3V. The third one is about its storage temperature range which would be from -65°C to +125°C. The fourth one is about its operating temperature range which would be from 0°C to +70°C.

Also some DC electrical characteristics about SA868. The first one is about its input high voltage which would be min 2V. The second one is about its input low voltage which would be max 0.8V. The third one is about its input leakage current which would be max 10uA. The fourth one is about its output high voltage which would be min 4.0V. The fifth one is about its output low voltage which would be max 0.4V. And so on. For more information about SA868 please contact us.
