High Accuracy Current Sense Amplifier Enables Current Sensing and Current Sharing: Maxim APP 391: Mar 01, 2001 / (added
8/03) -- Current sharing between DC/DC converter modules enables several modules to be paralleled. In recent years, tight tolerances for current sharing have made discrete current-sense
circuit designs a formidable challenge. This application note describes a low-cost, space-saving and accurate current sensing and sharing scheme using MAX4372. |

High
side Current monitor operates at high Voltage: 07/22/04 EDN Design Ideas / (added 1/05) The simplest technique for measuring current in an actuator or a motor is to
monitor the ground current with a resistive element between the load and the ground. Because the device and its associated electronics share a ground potential, you need to amplify only the
ground-current signal. This approach, however, does not detect device short circuits to ground, which can overload the high-side d...... |

High
side Current sensor monitors negative rail: 04/17/03 EDN Design Ideas / (added 1/05) All dedicated current-sense amplifiers provide high-side sensing on a positive
supply, but you can adapt such circuits for monitoring a negative supply (Figure 1). The positive-supply pin, V+, connects to the system's positive supply, and the ground pin, GND, connects to
the negative supply, VEE. That arrangement monitors the negative supply and provides a positive output voltage for the extern...... |

Improved Kelvin contacts boost Current sensing accuracy by an order of magnitude: 02/17/05 EDN Design Ideas / (added 5/05) Many power-supply designs rely on accurately
sensing the voltage across a current-sense element. Multiphase regulators use the sense voltage to force current sharing among phases, and single-phase regulators to control the current-limit
setpoint. As internal complexity and clock speeds increase, processors impose narrower operating margins for power-supply voltages and currents, which in turn m... |
