STMicroelectronics provides a recommended PCB layout in the application note AN4979, which includes guidelines for component placement, routing, and thermal management.
-
The sense resistor value depends on the desired current measurement range and the voltage supply. A general guideline is to choose a sense resistor value that results in a voltage drop of 50-100 mV at the maximum expected current.
-
The maximum allowed voltage on the sense pins is 6 V, exceeding which can damage the device. It's essential to ensure that the voltage on the sense pins does not exceed this limit.
-
Calibration involves adjusting the gain and offset of the current measurement circuit. STMicroelectronics provides a calibration procedure in the application note AN4979, which involves measuring the output voltage at different current levels and adjusting the gain and offset accordingly.
-
The thermal resistance of the VND600SP package is typically around 25°C/W, which means that for every watt of power dissipation, the junction temperature will increase by 25°C. Proper thermal management is essential to ensure reliable operation.
