TLE 6244X
Bit 0
1: no overvoltage at pin VDD
0: overvoltage at pin VDD resp. state of overvoltage still stored
Access by controller: read only
Testing the VDD-Monitoring:
Upper threshold:
By writing 000xxxxx in the register STATCON_REG the overvoltage threshold is reduced by
b
0.8V. In STATCON_REG Bit 0 has to be LOW then.
After writing 110xxxxx in the register STATCON_REG Bit 0 in STATCON_REG must be HIGH
b
again.
Lower threshold:
By writing 010xxxxx in the register STATCON_REG the overvoltage threshold is increased by
b
0.8V. In STATCON_REG Bit 1 has to be LOW then.
After writing 110xxxxx in the register STATCON_REG Bit 1 in STATCON_REG must be HIGH
b
again.
Example of configuration:
Requirement: After overvoltage ABE is to be LOW;
After overvoltage a self-test is carried out by the ECU, afterwards ABE is deactivated.
Register STATCON_REG is set to 111xxxxx during driving cycle.
b
When ABE becomes active, overvoltage can be detected by reading out STATCON_REG.
After the ECU’s self-test a reset condition is achieved by writing 110xxxxx into the register
b
STATCON_REG. This reset is only possible after disappearance of the overvoltage condition
because the set input is dominant. The reset signal is withdrawn by writing 111xxxxx .
