MAX4376/MAX4377/ MAX4378 Single/Dual/Quad, High-Side Current-Sense Amplifiers with Internal Gain General Description The MAX4376/MAX4377/MAX4378 single, dual, and quad precision high-side current-sense amplifiers are available in space-saving packages. They feature buffered voltage outputs that eliminate the need for gain-setting resistors and are ideal for today's notebook computers, cell phones, and other systems where current monitoring is critical. These precision devices are offered in three fixed-gain versions of 20, 50, and 100: GAIN SUFFIX 20 T 50 F 100 H For example, MAX4376TAUK is a single high-side amplifier with a gain of 20. High-side current monitoring is especially useful in battery-powered systems since it does not interfere with the ground path of the battery charger. The input common-mode range of 0 to +28V is independent of the supply voltage and ensures that the current-sense feedback remains viable even when connected to a battery pack in deep discharge. The full-scale current reading can be set by choosing the appropriate voltage gain and external-sense resistor. This capability offers a high level of integration and flexibility, resulting in a simple and compact current-sense solution. The MAX4376/MAX4377/MAX4378 operate over a supply voltage range of +3V to +28V, draw 1mA of supply current per amplifier, and operate over the full automotive temperature range of -40C to +125C. These devices have a wide bandwidth of 2MHz, making them suitable for use inside battery-charger control loops. The buffered outputs drive up to 2mA of output current into a ground-referenced load. The MAX4376 is available in a tiny 5-pin SOT23 package. The MAX4377/MAX4378 are available in space-saving 8-pin MAX(R) and 14-pin TSSOP packages, respectively.

Maxim Integrated 8 MAX4376/MAX4377/ MAX4378 Single/Dual/Quad, High-Side Current-Sense Amplifiers with Internal Gain Detailed Description The MAX4376/MAX4377/MAX4378 high-side current-sense amplifiers feature a 0 to +28V input common-mode range that is independent of supply voltage. This feature allows the monitoring of current out of a battery in deep discharge and also enables high-side current sensing at voltages greater than the supply voltage (VCC). The MAX4376/MAX4377/MAX4378 operate as follows: current from the source flows through RSENSE to the load (Figure 1). Since the internal sense amplifier's inverting input has high impedance, negligible current flows through RG2 (neglecting the input bias current). Therefore, the sense amplifier's inverting-input voltage equals VSOURCE - (ILOAD)(RSENSE). The amplifier's open-loop gain forces its noninverting input to the same voltage as the inverting input. Therefore, the drop across RG1 equals (ILOAD) (RSENSE). Since IRG1 flows through RG1, IRG1 = (ILOAD)(RSENSE)/RG1. The internal current mirror multiplies IRG1 by a current gain factor, , to give IRGD = x IRG1. Solving IRGD = x (ILOAD)(RSENSE)/RG1. Therefore: VOUT = b x (RGD/RG1)(RSENSE x ILOAD) x amp gain Applications Information Recommended Component Values The MAX4376/MAX4377/MAX4378 sense a wide variety of currents with different sense resistor values. Table 1 lists common resistor values for typical operation of the MAX4376/MAX4377/MAX4378. Choosing RSENSE To measure lower currents more accurately, use a high value for RSENSE. The high value develops a higher sense voltage that reduces offset voltage errors of the internal op amp. In applications monitoring very high currents, RSENSE must be able to dissipate the I2R losses. If the resistor's rated power dissipation is exceeded, its value may drift or it may fail altogether, causing a differential voltage across the terminals in excess of the absolute maximum ratings. If ISENSE has a large high-frequency component, minimize the inductance of RSENSE. Wire-wound resistors have the highest inductance, metal-film resistors are somewhat better, and low-inductance metal-film resistors are best suited for these applications. Bidirectional Current-Sense Amplifier where GAIN = 20 for MAX437_T. Systems such as laptop computers and other devices that have internal charge circuitry require a precise bidirectional current-sense amplifier to monitor accurately the battery's current regardless of polarity. Figure 2 shows the MAX4377 used as a bidirectional current monitor. This is useful for implementing either smart battery packs or fuel gauges. GAIN = 50 for MAX437_F. Current Source Circuit where amp gain is 2, 5, or 10. The part's gain equals ( x RGD / RG1) x amp gain. Therefore: VOUT = (GAIN)(RSENSE)(ILOAD) GAIN = 100 for MAX437_H. Set the full-scale output range by selecting RSENSE and the appropriate gain version of the MAX4376/ MAX4377/ MAX4378. www.maximintegrated.com Figure 3 shows a block diagram using the MAX4376 with a switching regulator to make a current source.
