Application Field

The TLV9002IDSGR is suitable for a variety of applications in industrial control, medical instrumentation, and power monitoring systems. Its low power consumption, wide bandwidth, and accurate current measurement capabilities make it ideal for demanding industrial applications. TLV9002IDSGR can be used in current sensing circuits to measure current flows as small as 0.1uA, while providing accurate and reliable performance across a wide range of conditions. It can be used to detect over-current and under-current conditions and to interface analog signals into digital systems. It is also suitable for applications in motor control, battery protection, solar inverter monitoring, load monitoring and current regulation.

Working Principle

The TLV9002IDSGR operates on the principle of logging two operating voltages of a p-channel MOSFET, the gate and the source. A low power current sense amplifier is used to measure the voltage difference between the two nodes. The amplifier has a gain of 1V/A. The voltage difference is then converted to a proportional output voltage using a programmable gain amplifier. The output voltage is linearly proportional to the measured current. This linear voltage output is then fed to the A/D converter of the system.

The TLV9002IDSGR is a gain stabilized current sense amplifier and features a programmable offset. The amplifier\'s output is also independent of the common mode voltage of the nodes being measured, making it suitable for applications that require sensing of multiple currents in different loops. The device also features programmable current limits and short-circuit protection, making it suitable for applications that require reliable performance in line with prevailing industrial standards.

Conclusion

The TLV9002IDSGR is an operational amplifier with high-side current sensing that is suitable for a variety of applications in industrial control, medical instrumentation, and power monitoring systems. It can measure current flows as small as 0.1uA, while providing accurate and reliable performance across a wide range of conditions.
