Over-Temperature Shutdown

The ZXLD1371 incorporates an over-temperature shutdown circuit to protect against damage caused by excessive die

temperature. A warning signal is generated on the STATUS output when die temperature exceeds 125°C nominal and the

output is disabled when die temperature exceeds 150°C nominal. Normal operation resumes when the device cools back

down to 125°C.
