Rohm has created a set of six current sense amplifiers with AEC-Q100 qualification for automotive use. They work with external shunt resistors, and there are two basic types: one (BD1423xFVJ-C) that can sense across the common-mode range of -14 to +80V and runs from 2.7 to 18V, and the other (BD1422xG-C) that can sense across -14 to +40V and runs ...

Ditronix has announced a multi-phase power and energy monitoring board in the form of a ‘Hat’ for Raspberry Pis. Called ‘IPEM PiHat’, it is based on Microchip’s M90E36A monitoring and power computation IC. “The board may be used as a stand-alone controller-monitor, or integrated within an IoT in-house or IoT cloud MQTT monitoring platform,” according to the company. “Safety is ...

Raspberry Pi has announced a second-generation of its computer-in-keyboard, and a branded monitor. Aimed at home computing and based on RP5 technology, the Raspberry Pi 500 keyboard computer has a quad-core 64bit Arm Cortex-A76 processor (with 8Gbyte of ram), wireless networking, dual display outputs, and 4K video playback. It comes with a 32GB Raspberry Pi SD Card pre-loaded with Raspberry ...

NXP is aiming at ASIL D safety approval with a vehicle battery junction box controller IC, intended to fire the pyrotechnic disconnect switch during a serious fault, as well as report faults over a serial bus. MC33777A, as it will be known, redundantly measures currents, voltages and temperatures, then deduces situations – a short circuit or a crash, for example ...

Diodes has created a range of precision current shunt monitors that have a -0.3 to 26V common-mode sense range irrespective of supply voltage, allowing both high-side and low-side measurement – and a reference pin is provided for bi-directional current measurement. Called the ZXCT21xQ family, there are six gain options: 50V/V  ZXCT213Q 75V/V  ZXCT215Q 100V/V  ZXCT214Q 200V/V  ZXCT210Q 500V/V  ZXCT211Q 1kV/V  ...

Sick of Hertfordshire has introduced a vibration, shock and temperature monitor for measuring signs of approaching machine failure. The harsh environment MPB10 Multi-Physics Box bolts on to industrial machines, including electric motors, pumps, fans and conveyor systems. “The MPB10 provides service data to enable predictive maintenance practices that can improve plant availability, maximise operating life, protect product quality and protect process ...

Infineon has introduced a chipset to implement its take on electric vehicle battery stack monitoring, using a combination of capacitive and transformer coupling to get cell charge-state data safely across the hundreds of volts present. There are two chips: TLE9012DQU, the Li-ion battery monitoring and balancing IC, which can handle up to 12 cells in series, and TLE9015DQU which interfaces a microcontroller ...

Anritsu has created the MS27201A remote spectrum monitor series, that includes a 43.5GHz version for new satellite downlink bands. A 110MHz measurement bandwidth supports common satellite downlink spans, DANL (displayed average noise level) is -164dBm and the typical TOI (third-order intercept point) is +20dBm. Other MS27201A versions work up to 9GHz or 20GHz. All work down to 9kHz. “Combining RF performance ...

Renesas has introduced a battery pack monitor for long strings of cells that uses an ac-coupled bus to solve the thorny problem of passing data up and down the line. At the same time, it revealed a high-side battery protection and monitoring IC for 4S to 16S cell battery packs. RAA489204 for long strings Stackable up to 30 ICs Up ...

Analog Devices is aiming at wearable patient monitoring devices with an analogue front-end for four vital signs: electrocardiogram, heart rate, blood-oxygen saturation and respiration rate. The chip, MAX86178, does this with three channels, one each for: photodiodes (optical PPG for blood oxygen and heart rate), voltages (electrocardiogram (‘ECG’ or ‘EKG’) and alternative heart rate) and bio-impedance (‘bio-z’ for respiration rate) Optical ...
