The MCP9843T-BE/MC is a digital temperature sensor from Microchip Technology, part of the MCP9843 family, designed for accurate temperature monitoring in embedded systems. It integrates an internal sensor with a sigma-delta ADC and register bank, outputting temperature data over an I²C/SMBus interface.
Package and board-fit considerations
Housed in an 8-VFDFN exposed pad package (supplier device package 8-DFN 2x3 mm), the MCP9843T-BE/MC is surface-mount and requires a thermal pad on the PCB for heat dissipation. The exposed pad also improves thermal coupling to the measured surface if the sensor is used for board-level temperature monitoring. The DFN package has a low profile, making it suitable for space-constrained designs.
It is ROHS3 compliant, meeting current environmental regulations for lead-free assembly.
