DRV5011ADLPGM datasheet by Texas Instruments

DRV5011ADLPGM Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the DRV5011ADLPGM?
  Texas Instruments provides a recommended PCB layout in the DRV5011 application note (SLVAE67). It's essential to follow this layout to ensure proper operation and minimize noise and EMI issues.
• How do I choose the right sense resistor value for my application?
  The sense resistor value depends on the current sensing range and the desired accuracy. A smaller sense resistor value provides a higher current sensing range but reduces accuracy. A larger sense resistor value provides higher accuracy but reduces the current sensing range. TI provides a sense resistor calculator tool to help with the selection.
• What is the maximum voltage that can be applied to the VCC pin?
  The maximum voltage that can be applied to the VCC pin is 5.5V. Exceeding this voltage can damage the device. It's essential to ensure that the power supply voltage is within the recommended operating range of 4.5V to 5.5V.
• How do I handle the output signal of the DRV5011ADLPGM?
  The output signal of the DRV5011ADLPGM is an analog voltage that represents the sensed current. This signal can be connected to an ADC or a comparator for further processing. It's essential to ensure that the output signal is properly filtered and conditioned to remove noise and ensure accurate measurements.
• What is the response time of the DRV5011ADLPGM?
  The response time of the DRV5011ADLPGM is typically around 1.5μs. This means that the device can respond to changes in the current signal within 1.5μs. However, the actual response time may vary depending on the application and the sense resistor value.
