TARQ474M035 Price of the High period of SCL. New data must be put onto the bus while SCL is Low. Bus timing is one clock pulse per data bit. The number of data bytes to be transferred is determined by the master device. The tota number of bytes that can be transferred in one operation is theoretically unlimited. VCB = 20V,IE = o VEB = 2V,IC = 0 VCE = 5V,IC = 50mA VCE = 5V,Ic = 300mA VCE = 5V,IC = 50mA VCB=lOV,f=lMHz VCB=lOV,f=lMHz Ic = lOOmA,IB = lOmA lC = lOOmA,IB = lOmA The L9638 provides a special operation mode for shorted LIN bus lines to ground. In that case, the whole LIN network is blocked. If the protocol handler in the hcC detects a "time out" condition, that could be un- ambiguously identified as a short to ground condition in the bus line, the whole LIN node could be discon- nected from the network by setting EN input to LOW. This will switch INH output from active HIGH to LOW. Additionally RxD output, that remains in the domi- nant state and maybe block the hcC will set to HIGH ohmic state. The L9638 won't accept any transition at TxD. This short circuit mode will be stable until the dominant state on LIN will be cleared. In that case, the device will switch to the sleep mode. According to that, the current consumption of a blocked LIN network will be reduced to the resulting short circuit current in the LIN line. Especially for sporadically happening shorts due to damaged cable isolation, the LIN network will be au- tomatically reset. Therefore no special power up procedure is required. |
