DATA SHEET www.onsemi.com High-Side Current Sensor FAN4010 SIP6 1.45X1.0 CASE 127EB Description The FAN4010 is a high−side current sense amplifier designed for battery−powered systems. Using the FAN4010 for high−side power−line monitoring does not interfere with the battery charger’s ground path. The FAN4010 is designed for portable PCs, cellular phones, and other portable systems where battery / DC power−line monitoring is critical. To provide a high level of flexibility, the FAN4010 functions with an external sense resistor to set the range of load current to be monitored. It has a current output that can be converted to a ground−referred voltage with a single resistor, accommodating a wide range of battery voltages and currents. The FAN4010 features allow it to be used for gas gauging as well as uni−directional or bi−directional current monitoring.

Care must be taken not to exceed the maximum power dissipation of the copper trace. The FAN4010 measures the voltage drop (VSENSE) across an external sense resistor in the high−voltage side of the circuit. VSENSE is converted to a linear current via an internal operational amplifier and precision 100 W resistor. The value of this current is VSENSE/100 W (internal). Output current flows from the IOUT pin to an external resistor ROUT to generate an output voltage proportional to the current flowing to the load. Use the following equations to scale a load current to an output voltage: V SENSE + I LOAD @ R SENSE V OUT + 0.01 V SENSE INPUT 0.3 in COPPER (eq. 1) R OUT Load − + (eq. 2) VOUT LOAD RSENSE 0.3 in COPPER 0.1 in COPPER 1 V IN Load 6 2 NC GND 5 3 I OUT NC 4 6 Rsense 100 W 3 I OUT VIN 1 + Vsense − V IN R OUT RLoad VOUT Figure 14. Using PCB Trace for RSENSE ROUT Selecting ROUT ROUT can be chosen to obtain the output voltage range required for the particular downstream application. For example, if the output of the FAN4010 is intended to drive an analog−to−digital convertor (ADC), ROUT should be chosen such that the expected full−scale output current produces an input voltage that matches the input range of the ADC. For instance, if expected loading current ranges from 0 to 1 A, an RSENSE resistor of 1 W produces an output current that ranges from 0 to 10 mA. If the input voltage range of the ADC is 0 to 2 V, an ROUT value of 200 W should be used. The input voltage and full−scale output current (IOUT_FS) needs to be taken into account when setting up the output range. To ensure sufficient operating headroom, choose: Figure 13. Functional Circuit Selecting RSENSE Selection of RSENSE is a balance between desired accuracy and allowable voltage loss. Although the FAN4010 is optimized for high accuracy with low VSENSE values, a larger RSENSE value provides additional accuracy. However, larger values of RSENSE create a larger voltage drop, reducing the effective voltage available to the load. This can be troublesome in low−voltage applications. Because of this, the maximum expected load current and allowable load voltage should be well understood. Although higher values of VSENSE can be used, RSENSE should be chosen to satisfy the following condition: 10 mV t V SENSE t 200 mV (R OUT @ I OUT ) such that FS V IN * V SENSE * (R OUT @ I OUT ) u 1.6 V FS (eq. 3) (eq. 4) Output current accuracy for the recommended VSENSE between 10 mV and 200 mV are typically better than 1%. As a result, the absolute output voltage accuracy is dependent on the precision of the output resistor. Make sure the input impedance of the circuit connected to VOUT is much higher than ROUT to ensure accurate VOUT values. Since the FAN4010 provides a trans−impedance function, it is suitable for applications involving current rather than voltage sensing. For low−cost applications where accuracy is not as important, a portion of the printed circuit board (PCB) trace can be used as an RSENSE resistor. Figure 14 shows an example of this configuration. The resistivity of a 0.1−inch wide trace of two−ounce copper is about 30 mW/ft. Unfortunately, the resistance temperature coefficient is relatively large (approximately 0.4%/°C), so systems with a wide temperature range may need to compensate for this effect.
