NCS199A1R, NCS199A2R, NCS199A3R Current-Shunt Monitors, Voltage Output, Bidirectional, Zero-Drift, www.onsemi.com Low- or High-Side Current Sensing The NCS199A1R, NCS199A2R, and NCS199A3R are voltage output, current shunt monitors (also called current sense amplifiers) which can measure voltage across shunts at commonmode voltages 1 from 0.3 V to 26 V, independent of supply voltage. The low offset of SC706 the zerodrift architecture enables current sensing across the shunt SQ SUFFIX with maximum voltage drop as low as 10 mV fullscale. These CASE 419B devices can operate from a single +2.2 V to +26 V power supply, drawing a maximum of 80 A of supply current, and are specified over MARKING DIAGRAM the extended operating temperature range ( 40C to +125C). Available in the SC706 package. 6 Features XXXM Wide Common Mode Input Range: 0.3 V to 26 V Supply Voltage Range: 2.2 V to 26 V 1 Low Offset Voltage: 150 V max XXX = Specific Device Code M = Date Code Low Offset Drift: 0.5 V/C max = PbFree Package Low Gain Error: 1.5% max (Note: Microdot may be in either location) Low Gain Error Drift: 10 ppm/C RailtoRail Output Capability PIN CONNECTIONS Low Current Consumption: 40 A typ, 80 A max REF OUT Typical Applications Current Sensing (HighSide/LowSide) GND IN Telecom Vs IN+ Power Management (Top View) Battery Charging and Discharging ORDERING INFORMATION See detailed ordering, marking and shipping information on page 2 of this data sheet.
