It uses a high side switch like this, with a set of matched transistors to detect even the slightest differential in the voltage across the FET to turn it on or On one end this means that we can’t have a 5 volt output from a 5 volt source as we typically lose 0.3v in the process. It's almost like a simple SR flip flop! :) Report comment Reply Bil Herd says: September 16, 2015 at 11:28 am Thanks It could have been done with a little N-Channel
Initial use was in body functions such as electric set motors or mirrors, but more recently the main factor has been the expansion of LED lighting. Thanks for the video tho :) Report comment Reply Bogdan says: September 18, 2015 at 8:37 am I like the high side integrated switches, like BTS4142N or the more powerful BTS441, Please allow 2-3 business days for reply. High Side Switch Transistor Sometimes you want to keep the same Ground reference to your circuits, so switching the positive terminal with a high side switch.

Figure 4 shows the block diagram of a VIPower device, plus four of the possible options: Reverse battery protection allowing self turn-on of power MOSFET Up to four channels with integrated Report comment Reply Graham Fountain says: September 18, 2015 at 3:03 pm Main reason for a high-side switch is where there is a common-ground path that can't be avoided.

High Side Load Switch With a high-side driver, it will short the driver output to ground, so the driver will need protection circuitry. Report comment Reply vedabrain says: September 16, 2015 at 11:00 am "A voltage drop of .057 ohms at 1 Amp means that the resistance of the FET in this case is Does the topology of the high side switch make that not an issue?

So there would constantly be current flowing through the LCD module. useful reference When I/O is "0", no current flows into the base of the NPN transistor, which means it won't conduct, and hence no current flows into the base of the PNP transistor Learn more about the new Power PROFET™ here eBook: POWER PROFET - A simpler solution with integrated protection for switching high-current applications efficiently & reliably 24V Protected Switch Shield with BTT6030-2EKA Report comment Reply Miroslav says: September 19, 2015 at 3:45 pm "A voltage drop of .057 volts at 1 Amp means that the resistance of the FET in this case is High Side Switch Wiki
oshpark liked Illumos Router. So the base of the PNP transistor is pulled down, and the PNP transistor is switched on. Initially the voltage is at VB, indicating the battery voltage under quiescent conditions. http://tuiconverter.com/high-side/high-side-n-channel-mosfet-switch-driver.php The BSP452CT-ND, for example, is a single-channel device with a 160 mΩ power switch that can output up to 700 mA; it is packaged in a SOT223-4.

If you have a circuit with only a battery on the input, there's no benefit to a high-side vs low-side.

STMicroelectronics, for example, uses a fabrication process that allows the integration of a digital or analog control circuit with a vertical power transistor on the same chip (Figure 3).

Report comment Reply Bil Herd says: September 16, 2015 at 11:37 am I prefer N-Chan also. That leaves a P-Channel Enhancement FET as our choice. For minimal power drain and/or extended temperature range, a path is needed from Q1 collector to some +ve rail. The resistors will need to be placed differently.
But your post on low side switching brings up two issues, if I'm interpreting it correctly -- residual voltage drop across the transistor could cause the signal level to the analog A similar circuit can be created with two MOSFETs.
