Integration Associates Introduces New High Voltage, High-Side Current Sense Amplifier.Business Editors/High-Tech Writers MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Oct. 27, 2003 Integrated IC Offers Complete, Uni-Directional, High-Side Solution in a Miniature SOT-23 Package Integration Associates, a fabless semiconductor company A fabless semiconductor company specializes in the design and sale of hardware devices implemented on semiconductor chips. It achieves an advantage by outsourcing the fabrication of the devices to a specialized semiconductor manufacturer called a semiconductor foundry or "fab. offering analog and mixed-signal semiconductor solutions for wireless and wireline communications, today announced the launch of the IA2410, a high voltage The term high voltage characterizes electrical circuits, in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to , high-side current sense amplifier. This amplifier is designed for current sense monitoring and control in a variety of portable electronic devices, as well as cellular infrastructure equipment, high-end routers, smart battery packs, and automotive applications. "The requirements for today's portable power management applications are becoming increasingly complex, which means that the components must be more integrated, more precise, more flexible, more efficient, and smaller than ever before," said Jean-Luc Nauleau, chief executive officer for Integration Associates. "The IA2410 has been engineered to maximize these values. When you consider all the relevant factors affecting overall cost-effectiveness, the IA2410 is an ideal drop-in part for challenging electronic designs that can utilize its high voltage, high-side current sense capability." The IA2410 is an ideal choice for application designers concerned about controlling costs and protecting valuable PCB PCB: see polychlorinated biphenyl.

This is an extremely cost-effective and value-added solution that has low power requirements and can sense a wide range of currents with different resistor resistor, two-terminal electric circuit component that offers opposition to an electric current. Resistors are normally designed and operated so that, with varying levels of current, variations of their resistance values are negligible (see resistance). values. In addition to design choices enabling the use of the tiny SOT-23 package, the IA2410 also comes with an internal temperature sensor that can further reduce the BOM by replacing the current sense resistor with a PCB copper trace. The IC temperature-sensing feature can be used to compensate for the temperature coefficient The temperature coefficient is the relative change of a physical property when the temperature is changed by 1 K. In the following formula, let R be the physical property to be measured, let T be the temperature of at which the property is measured. of the copper. Technical Specifications: The IA2410 operates from a single supply (5V to 36V) and offers a highly accurate (0.2% full scale) conversion of current output to a ground referenced voltage over the specified temperature range (-40 C to 85 C). Measuring very small voltage drops Noun 1. voltage drop - a decrease in voltage along a conductor through which current is flowing free fall, drop, dip, fall - a sudden sharp decrease in some quantity; "a drop of 57 points on the Dow Jones index"; "there was a drop in pressure in the pulmonary across a sense resistor, the IA2410 converts this voltage into a current output that is a small ratio of the measured current. This output is then used to monitor the value of the actual line current. The amplification factor of the current sense can be adjusted with a choice of external resistor ratios, so that a large range of current can be measured. Other key features are an output option for temperature measurement, 90uA supply current, 9uA max shutdown shut·down n.

Availability/Pricing: The IA2410 is available in either a 5-pin SOT-23 or 8-pin SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward.
