Furthermore, the IC is well-suited for applications that require two-stage over-temperature protection, such as power supplies and battery protections.

MCP98243T-BE/MCAB Working Principle

The MCP98243T-BE/MCAB works by using two independent temperature sensor inputs, one for the high side and one for the low side, to measure the temperature of the system. The measured temperature is compared to two adjustable reference points, which are configured with external voltage signals. When the measured temperature exceeds either of the reference points, one of the over-temperature protection (OTP) stages is activated, and a digital output is asserted to notify the host microcontroller. If the temperature gets too high, the second OTP stage will be activated and the IC will activate its temperature shut-off stages. These stages can be independently set and triggered by digital or analog signals. Once the temperature has been shut off, the host microcontroller will be notified via the Bidirectional Fault Signal (BDFS).

Conclusion

In conclusion, the MCP98243T-BE/MCAB is an excellent choice for power and thermal management applications due to its robust features, reliable operation, and wide variety of application fields. It provides the user with two adjustable temperature references, two OTP stages, two temperature shut-off stages, and a BDFS for monitoring the system’s temperature and status. This makes it a great choice for all types of applications, from embedded systems, to servers, to autonomous vehicles, and more.
