KE02: Bandgap Reference: Temperature Characterization

Hi NXP,

 

The KE02 includes a Bandgap Reference with a nominal trimmed value of 1.16 Vdc at 25C, but the Data Sheet (Rev.5, 01/2019) provides no indication on its value over the operating temperature range of the device (we are using the MKE02Z64VFM4) – could you please provide a response to the following questions:

 

  1. What is the expected range of Bandgap Reference values at the maximum ambient operating temperature of 105C (e.g. 25C Nominal +/- 2%)?
  2. What is the Temperature Coefficient of the Bandgap Reference?
  3. Do you have an Application Note providing details of a KE02 based Internal Temperature Measurement carried out using the Bandgap Reference?

 

Thank you for the assistance - CC
