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

Polymeric PTC Resettable Fuse 6V 3 A Ih Surface Mount 1812 (4532 Metric), Concave The 1812L300MR is a surface-mount resettable fuse (PPTC – Polymer Positive Temperature Coefficient) designed to provide overcurrent protection in electronic circuits.
