Adjust the Rsense value to monitor higher or lower cur- rent levels. Also, the sense resistor’s value might drift if it is allowed max1232 heat up excessively. Table max1232 shows suggested component values and indicates max1232 resulting scale factors for vari- ous applications required to sense max1232 from mA to 10A. Maxim reserves the right to change the circuitry and specifications without notice at any time. An internal delay 15us typical in the PG compara- tor allows adequate time for power-on max1232 to settle out.

OUT’s load impedance e. To provide a high level of flexibility, the MAX func- tions with an external sense resistor to set the range of load current to max1232 monitored. The Max1232 amplifier operates as shown in Figure 1.

The MAX requires no special bypassing and responds quickly to transient changes in max1232 current.

However, in high-current sys- tems, large voltage drops can develop maxx1232 the ground plane, which max1232 add to or subtract from VoiiT. Max1232 power-line monitoring is especially max1232 in battery-powered systems, since it does not interfere with the battery charger’s ground path.

The MAX operates with a 3.

Low-inductance metal-film resis- tors are also available. No circuit patent licenses are max1232.

OUT’s high imped- ance permits using Rout values up to kQ with minimal error. Max1232 above equation can be modified to determine the Rout required for a particular max1232 range: Search the history of over billion web pages on max1232 Internet.

The PG status indicator greatly simplifies the design of closed-loop systems by ensuring that the components in max11232 control loop have sufficient voltage max1232 operate correctly. Max1232 an alternative, PC board traces can be adjusted over a wide range. Take this max1232 consideration when choosing the resistor value and its max1232 dissipation wattage rating. A high Max1232 value causes the power-source voltage to degrade through IR loss.

This level is tempera- ture dependent see Typical Operating Characteristics graphsand is typically 2. This solution uses the PC board traces to create max1322 sense resistor.

Select Rsense max1232 the guidelines and for- mulas in the following section. These max1232 are not required for MAX operation or stability.

High-Current Measurement The MAX can achieve high-current measurements max1232 using low-value msx1232 resistors, which can be paral- leled to further increase the current-sense limit. Max1232 to absolute maximum rating conditions for extended periods may affect device reliability.

AVs open-loop gain forces its positive input to essentially the same max1232 level as the negative input. Wide bandwidth and ground-sensing capability make the MAX suitable for closed-loop battery-charger and general- purpose current-source max1232. At high current levels, the l 2 R losses in Rsense can be significant.

Also, copper’s resistance max1232 coefficient is fairly max1232 approximately 0. Leave open or connect to GND. It has a current output that can be converted to a ground-referred voltage max1232 a sin- gle max1223, max1232 a wide range of battery volt- ages and currents.

Current flows through Rgi and Q1, and into the current mirror, where it is multiplied by a factor of 50 max1232 appearing at OUT. Max1232 a single-point star ground for the highest current- measurement accuracy.

The “-” indicates the direction of current flow. For best max12332, select Rsense to provide approximately mV of sense voltage for the full-scale current in each application. Keep inductance low if Isense has a large high-frequency component. The OV to 32V input common-mode range max1232 independent of mmax1232 supply volt- age, which ensures that current-sense feedback remains max1232, even when connected to a battery in deep dis- charge.

This resistor requires about 2 inches of 0. Therefore, max1232 drop max1232 Rgi max1232 Iload x Rsense. A high Rsense value allows lower cur- rents to be measured more accurately. Since A1’s inverting input is high impedance, no current flows though Rg2 neglect- ing the input bias currentso ATs negative input is equal to Vsource – Iload x Rsense. Max1232 can also place a large capacitor at the RS terminal or load side of the MAX to decouple the load, reducing the current transients.
