10.24 Temperature sensor

[1]

The temperature sensor embedded in the PR533 is not intended to monitor the temperature. Its purpose is

to prevent destruction of the IC due to excessive heat. The external application should include circuitry to

ensure that the ambient temperature does not exceed 85

C as specified in Table 5 “Operating conditions”.
