Chip balances two 3.3V supercapacitors
Advanced Linear Devices has introduced a voltage balancing IC for series-connected pairs of 3.3V supercapacitors. Inside is a pair of mosfet-like devices with a sharp ‘knee’ in their voltage-current characteristic. As such, they are not literally balancing, but are clamping against over-voltage and passing spare current to the other cell. Called ALD910030, “this dual mosfet provides auto-balancing capabilities and power ...
3D Hall sensor for human-vehicle interfaces
Diodes is aiming at contactless rotary motion and proximity detection with a 3D Hall-effect magnetic field sensor. Automotive applications are envisaged, include infotainment rotary and push selectors, gear shifts, door handles and powered seat adjusters, it said. AH4930Q, as it will be known, comes in a ~3 x 3 x 1.5mm SOT-26 package and includes three sensors to detect a ...
1.5mΩ 48V automotive load switch
Infineon has revealed a 1.5mΩ protected load switch for 24V and 48V automotive systems. “With more than 1,000,000 switching cycles, the switches far exceed the average of conventional relays,” claimed Infineon. Called BTH50015-1LUA, it is functional across 12 to 54V, will work from 8 to 60V with some restrictions, and can survive over -0.3 to +70V. 1.5mΩ is a typical ...
More on: Isolated ADCs measure mV with a ±200V offset
Texas Instruments is aiming at robot motor control up to 60V with a series of isolated ADCs that include 200V barriers and come in 8pad 3.5 x 2.7mm VSON packaging. Each has a ΣΔ ADC on the hot side, an isolation barrier, then a digital interface on the cool side. The output is a modulated bit stream synchronised to an ...
2.1MHz low-side current sense amplifier
STMicroelectronics has introduced a 2.1MHz bandwidth low-side current-measurement amplifier in a 6-lead SOT23 pacakge. Dubbed TSC1801, it is aimed at motor control, solar power and automotive power conditioning. “The amplifier’s fast response allows pulse-by-pulse current control even in very high-frequency power-management systems,” according to the company, as well as “rapid over-current detection, protecting sensitive output-stage components against being damaged in ...
Modules embed Wi-Fi 6, Bluetooth LE 5.4 and Matter
Mouser is stocking Silicon Labs’ latest series of Wi-Fi 6, Bluetooth Low Energy 5.4 and Matter wireless modules, which measure 16 x 21.1 x 2.3mm. Called SiWG917Y, “the series are shielded modules with a dedicated wireless processing subsystem, an MCU and a security engine,” according to Mouser, which is stocking the parts. “The modules come with radio approvals for the ...
Embedded World: Sine/cosine to digital interpolation IC for positioning
iC-Haus has created a high-speed sine-to-digital signal conditioning interpolation IC for magnetic or optical position sensors. “Linear scales and angular sensors can benefit from higher resolution and accuracy, enabling an outstanding measurement precision, a faster motion speed or an improved control quality for drives,” claimed the company. By combining analogue and digital processing, the IC, called iC-NQE, takes in analogue ...
Isolated GaN gate driver in SO-8
Distributor Rutronik is stocking an isolated single-channel gate driver for GaN hemts that comes in a 4.9 x 6 x 1.65mm SOP-JW8 package. Made by Rohm and called BM6GD11BFJ-LB, they have “an isolation voltage of up to 2,500Vrms, a minimum input-output latency of 60ns and a minimum input pulse width of 65ns”, said Rutronik. “Under-voltage lock-out is integrated into the ...
±1ppb/°C 156.25MHz mems oscillator for SerDes and 800G links
SiTime has introduced SiT5977, a ±1ppb/°C mems-based 156.25MHz oscillator for network timing in data centres. It is “capable of driving 800G and higher links via 80fs phase jitter and LVDS outputs,” according to the company. Inside the tiny package, which measures 3.5 x 5mm, is what is claimed to be “the world’s most accurate silicon temperature sensor”. This sensor consists ...
