Описание:
This TIDA-00150 Design provides reference documentation on the PGA400-Q1 which will allow customers to quickly evaluate the automotive qualified PGA400-Q1 System on Chip (SoC) as an interface for their automotive resistive pressure sensor applications. The PGA400-Q1 has a built-in configurable Analog Front-End (AFE) with diagnostics, Sigma-Delta ADC, DACs, SPI, I2C, and a One-Wire Interface (OWI). Also with an integrated 8051 MCU and OTP memory, this chip enables a fully configurable system that can be easily matched to multiple automotive resistive pressure sensor applications. This design incorporates the PGA400Q1EVM board to create the solution.

Возможности:

Описание:
This shunt-based current sensor reference design provides an accuracy of < 0.2% FSR over a temperature range of -40°C to +125°C. Precision current sensing is essential in a number of automotive applications, including battery management systems, motor currents, and others. Generally, nonlinearity, temperature drift, shunt tolerances in these locations can cause poor accuracy results. This design solves these problems by using TI’s current shunt monitors and signal conditioners (INA240, PGA400-Q1).
Возможности:

Accuracy of 0.2% FSR, over temperature (-40°C to 125°C) Suitable for ±500A, high/low-side current sensing Compensated for temperature and non-linearity (second order temperature and linearity compensation algorithm) Protection against harness faults (overvoltage, reverse polarity, input/output signal protection) Electromagnetic interference (EMI) protection
