TI Korea (CEO Kent Jeon, www.ti.com/ww/kr ) August 30, 2012 – TI (CEO Kent Jeon) announced the addition of four new devices to its industry-leading current shunt monitor family. These ICs can monitor power current, voltage, and power values, achieving high accuracy while saving board space and the Bill of Materials (BOM). The INA3221, INA282, INA223, and LMP8480 current shunt monitoring devices are optimized for a wide variety of finished products, including smartphones, tablet PCs, computers, servers, power management devices, battery charging ICs, industrial applications, communications, and test equipment. (For more information on the products or to order samples, please visit www.ti.com/currentshunt-pr)

Key Features and Advantages
INA3221: 3-channel shunt and bus voltage monitor with I2C interface
• As the industry's first 3-channel device providing a digital interface, it can monitor three voltages and eliminates the need for separate devices for each voltage rail.
• Featuring a maximum offset voltage of 80µV and a gain error of 0.5%, it enables accurate current measurement and precise overcurrent detection when used in finished products such as laptops, desktop PCs, base stations, and servers.

INA282: Bidirectional high-precision current shunt monitor featuring a wide common-mode voltage range
• Save power consumption, board space, and BOM by using smaller shunt resistors with a 70µV maximum offset voltage and low gain error.
• As the first device to combine a wide common-mode voltage range (-14V to +80V) and a high common-mode rejection ratio (120dB), it achieves low offset voltage across multiple gain options. This combination provides higher accuracy in high-voltage applications, such as power equipment for industrial systems or telecommunications power systems.

INA223: Analog Output Current Shunt, Instantaneous Power, and Voltage Monitor
• As the industry's first analog multiple-output current shunt device, it provides multiplexed current, voltage, and instantaneous power values, saving board space and BOM.
• Provides programmable gains of 20, 128, and 300, allowing operation over a wide dynamic current load range without the need to switch sensing elements, thereby improving response time and accuracy in high-precision products such as battery-powered laptops, mobile phones, and tablet PCs.

LMP8480: Precision high-side current detection amplifier providing voltage output
• Features a wide common-mode voltage range of 4V to 76V and a wide power supply voltage range of 4.5V to 76V, allowing it to be driven by the same voltage node being monitored, thereby reducing system costs.
• Provides high detection accuracy in high-precision applications such as communications, automotive, and solar power monitoring with an input offset voltage (265μV) reduced by 50% compared to competitors

By combining various types of analog monitoring and control ICs that integrate INA3221, INA222, INA223, LMP8480 current shunt monitors, TI’s OMAP™ processors, Stellaris® ARM® Cortex™-M microcontrollers, LM75A or TMP75 temperature sensors, as well as analog-to-digital converter (ADC) and digital-to-analog converter (DAC) solutions such as AMC7812 or LMP92001, designers can develop comprehensive system management solutions.
