Wireless power supply chipset provides up to 1 W
ROHM Group company LAPIS Technology announced they have developed a chipset capable of providing up to 1W of wireless power for compact, streamlined wearable devices and for industrial smart, miniaturized, and sealing solutions. The ML7661 (transmitter) and ML7660 (receiver) eliminate the need for an external MCU by incorporating a control circuit required for transmission/reception, resulting in the industry’s smallest […]
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 […]
IoT PMIC uses a single inductor to power multiple rails
The new MAX77659 single-inductor multiple-output (SIMO) power management IC (PMIC) with integrated switch-mode buck-boost charger from Analog Devices, Inc. charges wearables, hearables, and Internet of Things (IoT) devices faster and in less space than any other PMIC available today. The MAX77659 SIMO PMIC delivers over four hours of playtime after a short, ten-minute charge, and […]
Ultra-low capacitance TVS diodes offer 3.8-V clamping
TDK Corporation has extended its range of TVS (transient voltage suppression) diodes characterized by their extremely low capacitance values for bidirectional overvoltage protection to include the ULC series (Ultra Low Clamping & Capacitance). The SD01005SL-ULC101 (B74111U0033M060) type has a minimum capacitance of ~0.5 pF and the SD0201SL-ULC101 (B74121U0033M060) type of ~0.6 pF, both at 1 […]
Glitch-free power supervisor IC protects low-voltage IoT apps
Designers can now enhance system reliability in low-voltage IoT applications with the Essential Analog MAX16162 nanoPower supervisor with glitch-free power-up from Maxim Integrated Products, Inc. This supervisor IC is the industry’s first to fully assert a system reset through the entire system power supply ramp; thereby eliminating low-voltage glitches during power-up and delivering higher system reliability. […]
Tiny high-power TVS diodes excel at ESD protection
TDK Corporation has released tiny high-power TVS diodes for ESD protection, extending its portfolio of components for bidirectional overvoltage protection of I/O interfaces. The space requirement of the so-called chip-scale package (CSP) is just 400 x 200 µm² (CSP01005) or 600 x 300 µm² (CSP0201), while the package height of just 100 µm is also […]
