The TPS65180/TPS65181 and TPS65180B/TPS65181B devices provide precise temperature measurement
function to monitor the panel temperature during operation. The TPS65180/TPS65180B requires the host
processor to trigger the temperature acquisition through an I2C write whereas the TPS65181/TPS65181B
automatically updates the temperature every 60 s.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
