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 DC Specifications 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.
