1 AVAILABLE General Description The MAX4372 low-cost, precision, high-side currentsense amplifier is available in a tiny, space-saving SOT23-5-pin package. Offered in three gain versions (T = 2V/V, F = 5V/V, and H = 1V/V), this device operates from a single 2.7V to 28V supply and consumes only 3µA. It features a voltage output that eliminates the need for gain-setting resistors and is ideal for today s notebook computers, cell phones, and other systems where battery/dc current monitoring is critical. 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 to 28V is independent of the supply voltage and ensures that the current-sense feedback remains viable even when connected to a 2-cell battery pack in deep discharge. The user can set the full-scale current reading by choosing the device (T, F, or H) with the desired voltage gain and selecting the appropriate external sense resistor. This capability offers a high level of integration and flexibility, resulting in a simple and compact current-sense solution. For higher bandwidth applications, refer to the MAX4173T/F/H data sheet.

No Connection. Not internally connected. Detailed Description The MAX4372 high-side current-sense amplifier features a to 28V input common-mode range that is independent of supply voltage. This feature allows the monitoring of current flow out of a battery in deep discharge, and also enables high-side current sensing at voltages far in excess of the supply voltage (VCC). Current flows through the sense resistor, generating a sense voltage (Figure 1). Since A1 s inverting input is high impedance, the voltage on the negative terminal equals V IN -. A1 forces its positive terminal to match its negative terminal; therefore, the voltage across R G1 (V IN - V1-) equals. This creates a current to flow through R G1 equal to / R G1. The transistor and current mirror amplify the current by a factor of β. This makes the current flowing out of the current mirror equal to: I M = β / R G1 A2 s positive terminal presents high impedance, so this current flows through R GD, with the following result: V2+ = R GD β VSENSE / RG1 R1 and R2 set the closed-loop gain for A2, which amplifies V2+, yielding: V = RGD β / RG1 (1 + R2 / R1) The gain of the device equals: V = R GD β (1 + R2 / R1) / R G1 VSENSE Applications Information Recommended Component Values The MAX4372 operates over a wide variety of current ranges with different sense resistors. Table 1 lists common resistor values for typical operation of the MAX V TO 28V CURRENT MIRROR I M R2 A1 A2 Figure 1. Functional Diagram RG1 1kΩ R G2 1kΩ Choosing RSENSE Given the gain and maximum load current, select RSENSE such that V does not exceed VCC -.25V or 1V. To measure lower currents more accurately, use a high value for RSENSE. A higher value develops a higher sense voltage, which overcomes offset voltage errors of the internal current amplifier. In applications monitoring very high current, ensure RSENSE is able to dissipate its own I 2 R 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.

Recommended Component Values FULL-SCALE LOAD CURRENT, I LOAD (A) CURRENT-SENSE RESISTOR, R SENSE (mω) GAIN (V/V) FULL-SCALE PUT VOLTAGE (FULL-SCALE = 1mV), V (V) Using a PC Board Trace as RSENSE If the cost of R SENSE is an issue and accuracy is not critical, use the alternative solution shown in Figure 2. This solution uses copper PC board traces to create a sense resistor. The resistivity of a.1-inch-wide trace of 2-ounce copper is about 3mΩ/ft. The resistance temperature coefficient of copper is fairly high (approximately.4%/ C), so systems that experience a wide temperature variance must compensate for this effect. In addition, self-heating will introduce a nonlinearity error. Do not exceed the maximum power dissipation of the copper trace. For example, the MAX4372T (with a maximum load current of 1A and an RSENSE of 5mΩ) creates a full-scale VSENSE of 5mV that yields a maximum V of 1V. R SENSE, in this case, requires about 2 inches of.1- inch-wide copper trace.
