Masach Tech recommends a 4-layer PCB with a dedicated ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad on the bottom of the device should be connected to a heat sink or a large copper area to ensure efficient heat dissipation.
Masach Tech provides a calibration procedure in the application note (AN-MS378-20C-001) that includes a series of voltage and current measurements. It is recommended to follow this procedure during manufacturing to ensure the device is properly calibrated and meets the specified accuracy and linearity.
Masach Tech recommends a pi-filter configuration (R-C-R) with a cutoff frequency of 100 kHz to minimize noise and EMI. The input filter should be placed as close to the device as possible to ensure optimal performance.
Masach Tech recommends using external overvoltage and undervoltage protection circuits to prevent damage to the device. A voltage supervisor IC can be used to monitor the input voltage and provide a reset signal to the device in case of an overvoltage or undervoltage condition.
Masach Tech recommends a soldering profile with a peak temperature of 260°C and a dwell time of 10-15 seconds. The device should be soldered using a no-clean flux and a solder with a melting point of 217°C or higher.
