      The MIC38C4xA are fixed-frequency, high performance, current-mode PWM controllers. Microchip’s BiCMOS devices are pin compatible with 384x bipolar devices, but feature several improvements. Undervoltage lockout circuitry allows the ‘42A and ‘44A versions to start up at 14.5V and operate down to 9V, and the ‘43A and ‘45A versions start at 8.4V with operation down to 7.6V. All versions operate up to 20V. When compared to bipolar 384x devices operating from a 15V supply, start-up current has been reduced to 100 μA typical and operating current has been reduced to 4.0 mA typical. Decreased output rise and fall times drive larger MOSFETs, and rail-to-rail output capability increases efficiency, especially at lower supply voltages. The MIC38C4xA also features a trimmed oscillator discharge current and bandgap reference. The MIC38C4xA family is available in 8-pin SOIC and MSOP-8 package options. For fast rise and fall times and higher output drive, refer to the MIC38HC4x.

      Excessive head resistance will cause compressor to trip

      Excessive head resistance will cause compressor to trip The existence of compressor failure does not seem to have much to do with the brand. In other words, whether it is a Hitachi compressor, a Copeland compressor, or another brand of compressor, as long as it is used for a long time, there will be some problems of failure. . Compressor tripping is a common fault. When this failure usually occurs, we should comprehensively look for the cause of the failure.

      What is the cause of insufficient displacement of Copeland compressor

      10/16/2020

      What is the cause of insufficient displacement of Copeland compressor

      Insufficient compressor displacement has a great impact on the entire refrigeration system. If it is not repaired and handled in time, it may cause problems such as the cylinder, cylinder head rupture, and compressor water intake, which will destroy the entire refrigeration system cycle. It may even cause accidents such as compressor combustion and explosion. So what causes the insufficient displacement of Copeland compressor? Let's take a look.
