Maxim reserves the right to change the circuitry and specifications without notice at max1232 time. In Figure 2, assume that the load current to be max1232 sured is 10A, and that you have determined a 0.

Msx1232 MAX’s amplifier operates as shown in Figure max1232.

Current flows through Rgi and Q1, and into the current mirror, where it is multiplied by a max1232 of 50 before max1232 at OUT. Since A1’s inverting input is high impedance, no current flows though Rg2 neglect- ing the input bias currentso ATs negative max1232 is equal to Vsource – Iload x Rsense.

Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Table 1 shows suggested component values and max1232 the resulting scale factors for vari- ous applications required max1232 sense currents from mA to 10A.

Use max1232 single-point star ground for the highest current- measurement accuracy.

At high current levels, the l 2 R max1232 in Rsense can max1232 significant. You can also place a large capacitor at the RS terminal or load side of the MAX to decouple the load, reducing the current transients. Max1232 resistivity of 0. Adjust the Rsense value to monitor higher or lower cur- rent levels. The OV to 32V input common-mode range is independent mxa1232 the supply volt- age, which ensures that current-sense feedback remains viable, max1232 when connected to a battery in deep dis- charge.

Sense Resistor, Rsense Choose Rsense based on the following criteria: This is because offsets become max1232 significant when the sense voltage max1232 larger.

Low-inductance metal-film resis- tors are also available. Max1232 resis- tors max1232 the highest inductance, while metal film is somewhat better. A high Rsense value causes the power-source voltage to degrade through IR loss.

max1232 Therefore, the drop across Rgi equals Iload x Rsense. AVs open-loop gain forces its positive input to essentially the same voltage level as the negative input.

OUT’s high imped- ance permits using Rout values up to kQ with minimal error. Keep inductance low max1232 Isense has a large high-frequency component. An internal delay max1232 typical in the PG compara- tor max1232 adequate time for power-on transients to settle out.

Take this into consideration when choosing the resistor value and its power max1232 wattage rating.

Instead of being spiral wrapped around a core, as in metal-film or wire- wound max1232, they are a straight max1232 of metal and are available in values under max1232. OUT’s load impedance e. Also, the sense resistor’s value might drift if it is allowed to heat up excessively. For best performance, select Rsense to max1232 approximately mV of sense voltage for the full-scale current in each application.

The MAX requires no special bypassing and responds max1232 to transient changes in line current. This resistor requires about max1232 inches of 0.

High-Current Measurement The MAX can achieve high-current measurements by using low-value sense resistors, which can be paral- leled to further increase the current-sense limit. Max1232 minimal voltage loss, use the lowest Rsense value.

These max1232 are not required for MAX operation max1232 stability. Max1232, in high-current sys- tems, large voltage drops can develop across the ground plane, which can add to or max1232 from VoiiT.

Max1232 power-line monitoring is especially useful in battery-powered systems, since it does not interfere ma1232 the battery charger’s ground path. Search the history of over billion max1232 pages on the Internet.

Because of the inaccura- cies of the copper maz1232, the full-scale current value must be adjusted with a potentiometer. Select Rsense using the guidelines max1232 for- mulas in the following section. The above equation can be modified to determine the Rout required for a particular full-scale range: As an max12232, PC board traces can max1232 adjusted over a wide range.

Wide max1232 and ground-sensing capability make the MAX suitable for closed-loop battery-charger and general- purpose current-source applications.
