Rohm Semiconductor announced they have developed compact wireless charger modules with an integrated antenna board: the BP3621 (transmitter) and the BP3622 (receiver). These new modules allow designers to add wireless power supply functionality to smaller devices such as smart tags/cards or PC peripherals. Wireless power supplies are increasingly being adopted in smartphones, smart watches, and other compact devices. […]

Compact contactors handle up to 250 A dc, 1,000 Vdc
TDK Corporation has extended its range of bipolar DC high-voltage contactors to include the new HVC43 (B88269X3**0C011) series. These products complete the existing range by offering continuous currents from 150 A DC to 250 A DC and operating voltages of up to 1000 V DC. The contactors are available in 12 V or 24 V […]
Current-sensing foil-on-ceramic resistors sport 2 milliohm resistance
High efficiency in consumer electronics has become increasingly important. For portable electronics, this means lower resistance values on current sense resistors for battery and power management. Stackpole’s CSRF series is a foil on ceramic carrier chip resistor that is designed for these applications. The CSRF2512 is now available in resistance values down to 2 milliohms. […]
Battery management system enables battery hot swapping in low-voltage EVs
Sensata Technologies announced the availability of its new i-BMS battery management system (BMS) for electrified applications up to 60V. The new i-BMS Battery Management System from Sensata’s Lithium Balance product brand, acquired by Sensata earlier in the year, is cell chemistry agnostic, compact, integrated BMS developed for the cost-optimized mass-production of applications up to 60V, such as […]
Battery management IC improves charge and fuel gauge accuracy
Analog Devices, Inc. announced the MAX17330 battery management integrated circuit (IC) with integrated fuel gauge and advanced battery protection for one-cell lithium-ion/polymer batteries that delivers a longer battery runtime for consumer applications than similar products. The new IC expands ADI’s battery management portfolio, which already delivers accuracy for the automotive and industrial markets that are […]
Battery charger IC handles low-voltage charging of wearables, compact IoT devices
The BD71631QWZ battery charger IC from Rohm Semiconductor is designed to provide low-voltage charging of wearables (e.g., wireless ear buds) and thin, compact IoT devices (e.g., smart displays) powered by rechargeable batteries. In recent years, the need for safer, higher density rechargeable batteries has led to the development of new battery types. This includes all-solid […]
Grid converter puts locally generated power on power grids
Siemens presents a new power conversion system for battery storage applications. The SINAMICS PCS grid converter makes locally generated batter power usable for industrial and public power grids. SINAMICS PCS controls the charging and discharging process of the battery and helps to handle load peaks and grid disturbances via the battery storage, to store the […]
High-current jumpers handle up to 7 A
Electronic circuits frequently require zero-ohm jumpers for ease of manufacture or to make trace routing easier. Some of these applications require current handling that exceeds the capabilities of general-purpose or high current jumpers. Stackpole’s HCJ series offers more than double the current rating of comparable high current jumpers. The HCJ current ratings range from 5.8A for […]
PXI, multi-cell battery simulator modules target automotive and aerospace applications
Pickering Interfaces launched a new family of battery simulator modules, ideal for Electric Vehicle (EV) battery stack emulation in Battery Management Systems (BMS) test applications. The 41-752A (PXI) and 43-752A (PXIe) modules enable direct voltage and current readback either programmatically or using Pickering’s soft panel control. Each cell simulator is highly accurate, specified at ±5 mV from 1 […]
1.5kW ac-dc power supplies offer CV and CC operation
Two new single-phase 1.5kW AC-DC power supplies from XP Power offer programmable constant voltage (CV) and constant current (CC) operation with analog and digital interfaces for user control. The compact and convenient solutions use an efficient resonant zero-volt switching (ZVS) topology and are suitable for equipment manufacturers in a wide range of industries including industrial, […]
