SensorTile.box wireless multi-sensor development kit with user-friendly apps for IoT and wearable sensor applications
This advanced motor implements closed-loop speed control to maintain precise RPM across load torque profiles. The DRV5013 Hall-effect sensor senses the magnetic rotor position, and the DRV8308 controller determines when to drive the CSD88537ND FET that energizes the coil . Without the use of a microcontroller or firmware, the sinusoidal current minimizes noise and torque ripple, maximizing motor performance.
The KITFS6523 evaluation board demonstrates the capabilities of the FS65xx and FS45xx product families. These safety SBCs target the ISO26262 automotive functional safety standard.
This shunt-based, isolated current measurement unit enables high-precision current measurement without the use of current transformers (CTs). Isolation is achieved through the AMC1304 which integrates high voltage isolation and a Delta-Sigma modulator . This solution avoids the need to use CTs, which is highly valued by customers as it reduces board size, product weight, crosstalk and EMI in the system, and reduces mechanical requirements by replacing CTs with shunts. problems, potentially extending product life.

This reference design features TI's DLP2010 (.2 WVGA) DMD chipset and is designed to enable ultra-low power and ultra-mobile displays either embedded into systems (e.g. smartphones, tablets, etc.) or as a standalone add-on module application. This chipset is used in designs containing the DLP2010 (.2 WVGA) DMD, DPC3435 display control, and DLPA2005 PMIC/LED driver.
This application note describes a two-phase, synchronous, step-down converter that is fully compliant with the AMD® K8 Low-Power Mobile Specification. It includes details of the circuit operation, schematic, bill of materials, and a 1.2 volt, 27.3 Amp reference design with test data.
This application note presents a simple, cost-effective, pre-IEEE® 802.3at PoE+ Powered Decice (PD) solution that employs the MAX5941B. The preliminary requirements of PoE+ PDs are discussed, as is the advantage of extending the existing MAX5941B circuit to implement a PoE+ PD. Test results including inrush-current limit, efficiency, output ripple, and dynamic response are presented for a 3.3V, 30W PD.
Brushed motors are a relatively popular motor design option due to their low price and simple control scheme. A brushed motor has a wound rotor and a permanent magnet stator. The motor is commutated via a conductive ring: this ring is connected to the rotor, which uses a brush to scrape against the commutator ring, thus commutation is achieved. Therefore, the direction of current flowing through the motor can change depending on the brush orientation and different commutation rings. Simple direction changes and speed control changes can be quickly and efficiently implemented on brushed DC motors using an H-bridge. An electronic driver is required to control the motor current in a brushed DC motor. The electronic drive circuit contains a power stage with a two-phase inverter (to meet the required power intensity), a microcontroller for implementing motor speed commands and fault handling, a current sensing function for motor start/stop protection, for control Gate drivers for two-phase inverters and power supplies for microcontrollers and other low-voltage devices.
The PMP11769 reference design is a comprehensive solution for 700W automotive audio amplifiers. This boost converter provides a 36.0V, 10.0A continuous/20.0A peak output from an input voltage of 9 to 16V. It contains two Class D amplifiers delivering 2 x 175W (loaded into 4 ohms, left and right channels) and 1 x 350W (loaded into 2 ohms, subwoofer) power.
This TEA1836 board demonstrates an ultra-compact, high power density, and cost-effective 45 W / 19.5 VAC/DC switch mode power supply (SMPS) wall adapter, typically used for ultrabook and tablet likely applications.
