This reset happens typically every 195ms when there is no output switching in either case. See also 1.2.2. A voltage reset causes a release of the output and output is in high state after power on again. 2 output will switch if magnetic signal is changing more that 2xBmin within offset recalibration time even below 6Hz once per magnetic edge, increased phase error is possible Data Sheet Page 2 of 3 TLE4928C supplement Revision History: April 2007 Version 3.0 Previous Version: 2.0 Page Subjects (major changes since last revision) 1 Data sheet is valid for 8" products 1 Ordering code added Infineon Technologies AG (c) Infineon Technologies AIM SC All Rights Reserved. http://www.infineon.com/products/sensors We Listen to Your Comments Any information within this document that you feel is wrong, unclear or missing at all?
