High Accuracy Current Sense Amplifier Enables Current Sensing & Current Sharing -
Maxim APP 391: Mar 01, 2001 / (app note added 5/08) -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 App 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:
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.....(design idea added 1/05) |

High side Current sense causes little error - 0316/95 EDN-Design Ideas: Measuring
dc would be simple if you could always reference your measurement signals to the
positive rail. Unfortunately, most current-metering applications require a
ground-referenced output. Typically, the signal that you want to measure consists of a
small differential signal that rides on a large common-mode voltage.....(design idea

High side Current Sensor has period output - 03/07/02 EDN-Design Ideas: You use
high-side current monitoring in many battery-powered products that require accurate
monitoring of load current, charger current, or both. In applications for nonportable
designs, high-side-current monitoring serves as a power-supply watchdog that can flag
a failure in downstream devices.....(design idea added 1/05) |

High side current Sensor monitors negative rail - 04/17/03 EDN-Design Ideas: 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.....(design idea added

Improved Kelvin contacts boost current sensing accuracy by an order of magnitude -
02/17/05 EDN-Design Ideas: 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.....(design idea added 5/05) |
