A1101ELHLT-T Frequently Asked Questions (FAQs)

  • A symmetrical layout with a central ground plane and minimal signal trace length is recommended. Allegro provides a reference layout in their application note AN296055.
  • Use a low-impedance current sense resistor (CSR) and ensure the CSR is placed close to the IC. Also, use a Kelvin connection to the CSR to minimize parasitic inductance.
  • The maximum allowable voltage on the VCC pin is 5.5V. Exceeding this voltage may damage the device.
  • The A1101ELHLT-T is rated for operation up to 150°C. However, the device's accuracy and reliability may degrade at high temperatures. Consult Allegro's application notes for thermal management guidelines.
  • Check the power supply, decoupling, and PCB layout. Verify that the device is properly configured and that the output signals are not overloaded. Consult Allegro's application notes and technical support resources for further assistance.
