Precision control of automotive proportional solenoids is necessary to achieve the precise control in an automatic transmission, in electronic fuel injectors, and in several automotive actuator applications. In proportional solenoids, the current flowing through the coil is directly oportional to the magnetic field generated. The designer can estimate armature position by knowing the current that is flowing through the solenoid. By forming a closed-loop solenoid control with high-accuracy current sensors, the designer is able to control the proportional olenoid in a precise manner. This order of control implies that highaccuracy current sensors are critical to achieve precise control of solenoids. Some of the main aspects to consider when selecting a current sensor are less offset, less drift, and higher pulse-width-modulation (PWM) rejection ration. By combining the above three features, this reference design shows a way to precisely measure the current flowing through the solenoid using TI's current shunt monitoring portfolio.
Возможности:

Uncalibrated accuracy: less than 1% for more than 10 mA over temperature (–40°C to 125°C) Suitable for various solenoid current ranges Low drift, high precision High-side drive, high-side solenoid monitor Enhanced PWM rejection facilitates uniform current profile Lowers blanking time and enables accurate measurements at lower duty cycle

Thisreference design provides detection of traction motor phase currents. The TIDA-01543 design realizes an isolated current sensor solution. Precise in-line huntbased, motor phase current sensing is done with AMC1305M05-Q1 delta-sigma (ΔΣ) modulators and the INA301-Q1 device. The high CMTI of the modulator helps suppress inverter switching transients from corrupting the data on the controller side. The fast response time of the INA301-Q1 enables faster reaction times for overcurrent events. The TIDA-01543 provides an interface to connect to an external MCU where digital SINC filters can be implemented to demodulate the AMC1305M05 output bit stream. This TI Design uses the C2000 family, automotive-qualified F280049M Piccolo™ icrocontroller control card.

This reference design shows how to detect current from the mA-to-KA range using a busbar-type shunt resistor. The increasing demand of high-capacity batteries in electric vehicles (EVs) and hybrid electric vehicles (HEVs) drives the requirement for larger current spans and highly-accurate current sensors. Obtaining a good accuracy over three decades (mA to A, 1 A to 100 A, and 100 A to 1000 A) is quite challenging due to large amounts of noise in the system. This design solves this problem by using a high-resolution analog-to-digital converter (ADC) and high-accuracy current shunt monitors from TI.
