49 / 70 page ![]() Final Data Sheet 49 V4.2, 2003-08-29 TLE 6244X 3.6 Power outputs 2.2A/45V OUT9...OUT14 In case of open input (parallel con- trol) or missing power supply the power stage is switched off. Paral- lel connection of power stages is possible. 3.6.1 Nominal Cur- rent C IOUT9.. .14 2.2 A 3.6.2 Extended Cur- rent Range IOUTi > 2.2A Accumulated operating time C 100 h 3.6.3 Maximum Current (Short Circuit Shut down Threshold) 4.5V ≤ UUBatt ≤ 17V for OUT11..14 4.5V ≤ UUBatt for OUT9/10 TJ = -40°C TJ = 150°C B A IOUTi IOUTi 2.4 2.2 3.8 3.7 A A UUBatt > 21V for OUT11...14 TJ = -40°C TJ = 150°C B A IOUTi IOUTi 3 2.7 5 4.6 A A For OUT11... OUT14 Above this limit short circuit to UBatt is detected. For the duration of the shutoff delay time tVoff (see 3.6.4) the output current is limited to approximately this value. If the short circuit condition is still present after tVoff, the outputs OUT11...OUT14 are switched off. An error is stored after tDiag (see 3.11.4). The same is true for OUT9, OUT10 if the static current limita- tion is not enabled. Between -40°C and 150°C an approximately linear characteristic line can be assumed. Between 17V ≤ UUBatt ≤ 21V, the short circuit shutdown threshold is switched for OUT11..14 |
