PRODUCTION DATA
A built-in thermal monitoring diode is made available on the TDIODE+ and TDIODE– pins. This diode facilitates temperature monitoring and characterization of the device in higher ambient temperature environments. Although the on-chip diode is not highly characterized, the diode can be used effectively by performing a baseline measurement (offset) at a known ambient or board temperature and creating a linear equation with the diode voltage slope provided in the Recommended Operating Conditions table. Perform offset measurement with the device unpowered or with the PD pin asserted to minimize device self-heating. Only assert the PD pin long enough to take the offset measurement. Recommended monitoring devices include the LM95233 device and similar remote-diode temperature monitoring products from Texas Instruments.
