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 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.

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.
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.

TIDM-CAPTIVATE-64-BUTTON TI reference design demonstrates an ultra-low power touch panel with 64 buttons that can be controlled from a single MSP microcontroller (MCU) with CapTIvate™ technology. The design uses mutual capacitance technology to ensure that all 64 buttons are tightly packed and can be controlled with just 16 MCU pins. This touch panel easily connects to the CAPTIVATE-FR2633 MCU target module included in the MSP-CAPT-FR2633 MCU development kit.
This reference design utilizes an isolated modulator and independent digital filter to implement a Class 0.5 three-phase power measurement system with an isolated shunt sensor, eliminating the need for an integrated synchronization filter and allowing an optional host microcontroller (MCU). ) will be broader in scope. In this design, the current sensed by the isolated modulator and the phase voltage sensed by the host microcontroller are synchronized; more advanced metering algorithms are supported using the Simplelink™ ARM Cortex M4 host MCU. This design protects against magnetic tampering attacks by using current sensors and a power supply that does not use any transformers or other magnetic components. This subsystem design has been tested and includes hardware.
