ADVANCE INFORMATION
Refer to the PDF data sheet for device specific package drawings
The separation between the input conductor and the Hall sensor die due to the TMCS1126 construction provides inherent galvanic isolation between package pins 1 and 2 on the high-voltage input side, and package pins 3 through 10 on the low-voltage output side. Insulation capability is defined according to certification agency definitions and using industry-standard test methods as defined in Insulation Specifications. Assessment of device lifetime working voltages follow the VDE 0884-11 standard for reinforced insulation, requiring time-dependent dielectric breakdown (TDDB) data-projection failure rates of less than 1 part per million (ppm), and a minimum insulation lifetime of 30 years. The VDE standard also requires additional safety margins of 20% for working voltage, and 30% for insulation lifetime, translating into a minimum required lifetime of 39 years at 900 VRMS for the TMCS1126.
