TMCS1101A2UQDR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the application note SLVAE25, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The TMCS1101A2UQDR has a programmable gain amplifier that allows for different current sensing ranges. The gain can be set through the GAIN pin, which can be connected to a resistor divider network or a digital potentiometer to select the desired gain setting.
  • The maximum allowable voltage on the VS pin is 5.5V, which is the absolute maximum rating. However, for normal operation, the recommended voltage range is 3.0V to 5.0V.
  • When the input current is zero, the output voltage of the TMCS1101A2UQDR will be approximately half of the supply voltage (VS/2). This is due to the internal voltage reference and the output stage of the device. To handle this, you can add a voltage reference or a voltage divider network to shift the output voltage to a desired level.
  • The thermal resistance of the TMCS1101A2UQDR package (QFN-16) is 34.4°C/W (junction-to-ambient) and 10.4°C/W (junction-to-case). This information is available in the datasheet, but it's often overlooked.
