STR3A155D Frequently Asked Questions (FAQ)
-
Allegro recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a separate layer for the power supply and output signals. Keep the sense lines as short as possible and away from noise sources.
-
Use a Kelvin connection for the sense lines, and ensure the sense lines are twisted and shielded to minimize noise. Also, use a low-impedance path for the sense lines and keep them away from high-current paths.
-
The output pins are open-drain, so they can withstand up to the supply voltage (VCC) without damage. However, it's recommended to keep the output voltage below VCC - 0.5V to ensure proper operation.
-
The STR3A155D is rated for operation up to 150°C, but it's recommended to derate the current measurement accuracy above 125°C. Consult the datasheet for temperature-related specifications and consider using a heat sink if necessary.
-
Use a shielded enclosure, and ensure the PCB is designed with EMI in mind. Use a common-mode choke or ferrite bead on the sense lines, and consider adding EMI filters on the power supply and output signals.
