Typical implementations of distance measurements use expensive rare-earth magnets. To lower overall system cost, this reference design walks through the implementation of industry’s first inductance-to-digital converters from TI for linear position sensing without the use of any expensive rare-earth magnets. Linear position sensing determines the position of a target that moves laterally across an inductive sensor that is generating a magnetic field. An inductance-to-digital converter (LDC), like the LDC1000 or LDC1101, senses inductance changes of an inductor that comes into proximity with a conductive target, such as a piece of metal. The LDC measures this inductance shift to provide information about the position of a conductive target over a sensor coil. The inductance shift is caused by eddy currents generated in the target due to the magnetic field of the sensor. These eddy currents generate a secondary magnetic field that opposes the sensor field, causing a shift in the observed inductance.

The TI Design TIDA-00475 demonstrates contactless, robust, cost effective, position sensing for variable speed trigger switches common in power and garden tools. The MSP430G2x53 microcontroller determines accurately the trigger position and generates the PWM signal to control motor speed and torque. This capacitive potentiometer enables by design high reliability, long life time, and robust operation in harsh environments. The contactless sensing is inherently neither effected by wear down nor moisture or dirt. Therefore it is an ideal replacement for sensitive resistive potentiometers in cost sensitive applications and resolves their reliability issues in harsh environments. The very low power standby operation of the system avoids discharge and damage to the battery pack in case of long term storage.

Возможности:

Cost-efficient accurate position sensing Robust operation in harsh environment in presence of temperature, humidity, supply voltages variations and electromagnetic disturbances Step-less high resolution speed command Long lifetime of the trigger switch Low operation and standby current

The Sitara AM437x simplified power sequence feature provides flexibility to power designers. This reference design implementation is a BOM-optimized discrete power solution for the AM437x processor with a minimal number of discrete ICs and basic feature set. The solution represents a baseline of a discrete power solution that can be extended for additional features and capabilities of the AM437x processor.

Возможности:

Simplified, BOM-optimized discrete power solution for the Sitara AM437x processor. AM437x includes an integrated LDO that simplifies processor power sequencing requirements. Systems without controlled power down can greatly benefit from this feature since the integrated LDO always ensures power up/down sequencing is met for VDDS and VDDSHVx supplies The TLV62565 step down converter provides the 3.3 volt supply and the TLV62080 provides the 1.1 volt supply. Two TLV702xx low drop out regulators (LDOs) provide the 1.5-V and 1.8-V supplies. TLV803M voltage supervisor keeps the processor in reset until all rails are operational and to reset the processor when input power is lost. This design is tested and includes schematics, BOM, design guide, and test data.

TI provides the system solution for Industrial Communication on Sitara™ processors with Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS). PRU-ICSS allows custom firmware applications in the field of real-time applications. The I2C peripheral on many application processors does not support SMbus commands like block read and block write transfers. This TI Design implements those SMbus commands with standard I2C commands into the PRU-ICSS peripheral.
