Method provides automatic machine shutdown : 05/27/04 EDN Design Ideas / (added 1/05) Some machines need to run for long periods and therefore may finish their work
in the middle of the night or during the weekend. For the time remaining, until the operator returns, the machines stay idle, uselessly consuming power. This Design Idea allows a machine to
completely shut itself down after finishing its work. |

MOSFET Replaces Switch #1: 01/20/94 EDN-Design Ideas / (Electronic Circuit diagram added 03/03) By using a cheap,
readily available MOSFET, you can use a single-pole switch to turn a bipolar power supply on and off without consuming extra power. In Fig1, the switch simply controls the MOSFET gate, which
switches on the negative supply. Resistor R, which can be several megohms, is not necessary if the ±6V rails are permanently connected to a load, such as an op-amp circuit. Because the MOSFETs
RDS (ON) is a fraction of an ohm, power loss is minimal, and the circuit suits moderate-consumption, battery-operated circuitry |

Multiple Remote Points
Control on/Off Switch: 06/22/00 EDN-Design Ideas / (Electronic circuit added 5/02) / Sometimes, you need to remotely turn on or off a two-state system, such as a light, from multiple
points. You could connect simple pushbutton switches in parallel to a single-line bus. However, if the bus simply controls a toggle flip-flop, the system must know its current state to
positively ensure the new, desired state. For example, if you want to make sure the light is on, you must have visual or electrical feedback via a second line before deciding whether to toggle
the flip-flop. Also, bounce-free pushbutton switches are necessary. The circuit in Figure 1 achieves positive state control according to the length of time you activate any pushbutton switch
from S1 to SN. An activation of a few milliseconds, for example, guarantees that the system is set to one state. An activation of 1 sec, for example, guarantees that the system is set to the
other state. No visual or electronic feedback is necessary.... |

Negative Voltage Load Switch : The idea is simply to turn off the negative voltage load. Some examples:-- Bias votlages for
LCD panels - RF Amplifiers - Audio Amplifiers.
The good thing about this design is that i can make use of the system i/o voltage to control the on/off and this is the whole idea. However, there are many many type of load switches that turn
of negative voltages. (added 11/05) |
