0.2 mOhms ±1% 9W Chip Resistor Nonstandard Anti-Sulfur, Automotive AEC-Q200, Current Sense, Moisture Resistant, Pulse Withstanding Metal Element The WSLP3921L2000FEA is a power metal strip current sense resistor manufactured by Vishay Dale, designed specifically for precision current measurement applications in power electronics circuits. It belongs to the WSL/WSLP family, a line of low-resistance, high-power surface-mount resistors built using a metal strip element rather than conventional thick-film or thin-film resistive technology, giving it characteristics that are particularly well suited to current sensing rather than general-purpose resistive applications. The defining characteristic of this component is its very low resistance value, which allows it to be placed in series with a current path while introducing minimal voltage drop and power loss, while still producing a measurable voltage signal proportional to the current flowing through it. This voltage signal can then be read by current-sense amplifiers, comparators, or analog-to-digital converters to provide accurate real-time current feedback for power supply regulation, overcurrent protection, battery management, motor control, and similar applications where knowing the instantaneous current is essential to safe and efficient operation. The metal strip construction used in this series offers a low temperature coefficient of resistance compared to thick-film alternatives, meaning the resistor's value remains more stable across varying operating temperatures, which directly improves the accuracy of current measurements taken over a wide thermal range. The element is also engineered for low thermal EMF and minimal self-inductance, both of which are important for maintaining measurement fidelity in fast-switching power conversion circuits where parasitic effects can otherwise distort the sensed signal. This particular part is qualified to automotive component reliability standards, reflecting its suitability for use in vehicle electrical systems, battery packs, and other safety- or reliability-critical power applications where component robustness under thermal cycling, vibration, and long-term stress must be assured. The device also features moisture-resistant and pulse-withstanding construction, along with a nonstandard anti-sulfuration design intended to resist corrosion-related resistance drift that can occur in resistors exposed to sulfur-containing environmental contaminants over time, a known failure mode in some conventional thick-film resistor technologies. The component is housed in a surface-mount package and is supplied on tape-and-reel packaging suitable for automated assembly, with construction compliant to RoHS material restrictions.

Power Supply Controller Digital Power Monitor 10-VSSOP The INA228 is an ultra-precise digital power monitor with a 20-bit delta-sigma ADC specifically designed for current-sensing applications. The device can measure a full-scale differential input of ±163.84 mV or ±40.96 mV across a resistive shunt sense element with common-mode voltage support from –0.3 V to +85 V. The INA228 reports current, bus voltage, temperature, power, energy and charge accumulation while employing a precision ±0.5% integrated oscillator, all while performing the needed calculations in the background. The integrated temperature sensor is ±1°C accurate for die temperature measurement and is useful in monitoring the system ambient temperature. The low offset and gain drift design of the INA228 allows the device to be used in precise systems that do not undergo multi-temperature calibration during manufacturing. Further, the very low offset voltage and noise allow for use in mA to kA sensing applications and provide a wide dynamic range without significant power dissipation losses on the sensing shunt element. The low input bias current of the device permits the use of larger currentsense resistors, thus providing accurate current measurements in the micro-amp range. The device allows for selectable ADC conversion times from 50 µs to 4.12 ms as well as sample averaging from 1x to 1024x, which further helps reduce the noise of the measured data. • High-resolution, 20-bit delta-sigma ADC • Current monitoring accuracy: – Offset voltage: ±1 µV (maximum) – Offset drift: ±0.01 µV/°C (maximum) – Gain error: ±0.05% (maximum) – Gain error drift: ±20 ppm/°C (maximum) – Common mode rejection: 154 dB (minimum) • Power monitoring accuracy: – 0.5% full scale, –40°C to +125°C (maximum) • Energy and charge accuracy: – 1.0% full scale (maximum) • Fast alert response: 75 μs • Wide common-mode range: –0.3 V to +85 V • Bus voltage sense input: 0 V to 85 V • Shunt full-scale differential range: ±163.84 mV / ±40.96 mV • Input bias current: 2.5 nA (maximum) • Temperature sensor: ±1°C (maximum at 25°C) • Programmable resistor temperature compensation • Programmable conversion time and averaging • 2.94-MHz high-speed I2C interface with 16 pinselectable addresses • Operates from a 2.7-V to 5.5-V supply: – Operational current: 640 µA (typical) – Shutdown current: 5 µA (maximum) #CommonPartsLibrary #IntegratedCircuit #PowerManagement
