应用须知
- Optimizing Performance of the PGA450-Q1PDF, 156 Kb, 档案已发布: Jun 23, 2015
The PGA450-Q1 device must be optimized and fine-tuned for each particular application. All supporting materials provided by TI for the PGA450-Q1 have been optimized for Texas Instruments' lab-bench setup. The PGA450-Q1 device is not ensured to perform identically in an end-user’s test environment because of varying environmental factors.These factors include temperature, humidity, air p - Using a fixed threshold in ultrasonic distance-ranging automotive applicationsPDF, 753 Kb, 档案已发布: Jul 17, 2012
- LIN Demonstration using PGA450Q1EVM Firmware Rev 2.1 (Rev. A)PDF, 644 Kb, 修订版: A, 档案已发布: Jul 13, 2015
This demonstration is intended to illustrate the method of using the internal 8051 MCU firmware of the PGA450-Q1 device to calculate the time of flight (tof) using LIN communication to trigger a distance computation. The settings for short distance measurements have been updated from Rev. 2.0 to Rev 2.1 of the firmware. Differences include an optimized threshold algorithm (optimized for the TI set - Automatic Slave Node Position Detection (SNPD) for PGA450-Q1PDF, 50 Kb, 档案已发布: Jun 17, 2015
This application note describes how to automatically detect the position of the slave nodes on the LIN bus and assign a unique ID to each device. - PGA450-Q1 Reset Issue During VPWR Ramp DownPDF, 35 Kb, 档案已发布: May 24, 2016
During a VPWR ramp down, the 8051W microcontroller comes out of reset incorrectly when VPWR is between the typical values of 3.5 V and 3.2 V which leads to faulty code execution. This application report describes this issue and the workaround for this issue. - 3Q 2012 Issue Analog Applications JournalPDF, 4.5 Mb, 档案已发布: Jul 17, 2012
