These ASIL-compliant devices can measure voltage, current, and temperature. Customers will be provided with flexibility and design reusability in their electric vehicle (EV) power systems. The MLX91230, […]
Current sensing for energy efficient power delivery
It pays to know the limitations and strengths of widely used methods of measuring current. Sam Locke • Allegro Microsystems Recent technological developments such as fast dc charging for electric vehicles and high-power processing in data centers drive the quest for delivering more power in smaller spaces. Congruent with that quest is the need for […]
Proof-of-concept platform evaluates ambient light and heat micro-power sources
Trameto has introduced a proof-of-concept platform for evaluating how to generate a reliable micro-power source from ambient light and heat. Called Severn, the compact platform can be used as a prototype because its size and form factor could be adopted for production. An engineering sample of the TM2040, a four-input, smart EH PMIC is at […]
Current-sense shunt resistor offers 0.5 milliohm resistance, 3-W power rating
High-efficiency current sensing requires low resistance values. However, lead resistance may cause inaccuracies in sensing measurement for ultra-low resistance values. Four terminal Kelvin connections with separate sense and current flow connections eliminate the detrimental effects of lead resistance yielding a very accurate measurement of the power delivered. Stackpole’s CSSK3637 is a four-terminal device offering resistance […]
Battery-free BLE sensor beacon wirelessly powered over 120 ft away
Powercast Corporation and InPlay have created a platform for designing battery-free, maintenance-free, long-range wireless IoT sensor systems that deploy easily for monitoring in the retail, medical, warehousing, and industrial IoT markets. Powercast (booth #641) and InPlay (booth #333) will both demonstrate at Sensors Converge in San Jose how Powercast’s RF-to-DC power harvesting technology is a compelling new option […]
Dual-channel low-side 4/5-A gate driver ICs handle fast MOSFET, WBG switches
Infineon Technologies AG has released the new EiceDRIVER 2EDN product family. Aiming at space-limited designs, the next-generation devices complement the existing 2EDN driver ICs by providing higher system-level efficiencies, excellent power density, and consistent system robustness with fewer external components. Building upon this expansion, the 2EDN family is now able to drive the power switch […]
Four-terminal shunts provide precision current sensing
Low resistance values are important for high-efficiency current sensing because lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values accurately becomes challenging because of lead resistance errors. Using a four-terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation. The HCSK1216 provides […]
Fully integrated current sensor excels at wide bandgap power applications
ACEINNA announced the high current ±65 Amp MCx1101 Current Sensor, the industry’s most accurate and highest bandwidth current sensor. Designed for WBG (wideband gap) applications, and available in 3.3- and 5-Volt versions, this highly accurate, wide bandwidth AMR-based (Anisotropic Magnetoresistive) current sensor is ideal for a wide range of next-generation power systems and applications. Units […]
