TLE 6251 G
Other Features
V_µC-level Adapter
The advantage of the adaptive µC logic is the ratiometrical scaling of the I/O levels depending on
the input voltage at the V_µC pin. So it can be ensured that the I/O voltage of the µC fits to the
internal logic levels of the TLE 6251 G.
WAKE Input
The wake-up input pin is a bi-level sensitive input. This means that both transitions, HIGH to
LOW and LOW to HIGH, result in a wake-up.
V_CC, V_µC Undervoltage Detection
If an undervoltage condition at V_CC, V_µC is detected for longer than t = t_UV,t, the TLE 6251 G
automatically transfers into the sleep mode and the undervoltage flag is set. This flag is an internal
flag and not available via NERR or RxD. The flag is cleared again, after setting the power on or
wake flag (power-up or wake-up).
V_S Undervoltage Detection
If an undervoltage condition at V_S is detected, the TLE 6251 G immediately transfers into the
standby mode and the undervoltage flag is set. This flag is an internal flag and not available via
NERR or RxD. The flag is cleared again, after the supply voltage V_S has reached the nominal
value.
