A3950SLPTR-T Frequently Asked Questions (FAQ)

  • A good PCB layout for the A3950SLPTR-T involves keeping the high-current paths short and wide, using a solid ground plane, and placing the device close to the battery. Allegro provides a recommended PCB layout in their application note AN296050.

  • The sense resistor (Rs) should be chosen based on the desired current sense accuracy and the maximum current rating of the device. A smaller Rs value provides better accuracy but increases power loss, while a larger Rs value reduces power loss but decreases accuracy. Allegro provides a sense resistor calculation tool to help with this selection.

  • The A3950SLPTR-T has an operating temperature range of -40°C to 150°C, but the device can be derated for high-temperature operation. Consult the datasheet for derating curves and thermal management guidelines.

  • The A3950SLPTR-T has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection can be achieved by using external components such as TVS diodes or Zener diodes to clamp voltage transients and prevent damage to the device.

  • A 10 μF to 22 μF ceramic capacitor is recommended for the VCC bypass capacitor to ensure stable operation and reduce noise. The capacitor should be placed as close to the VCC pin as possible.
