Description
Technical Field
The utility model belongs to the technical field of the on-vehicle battery fuse box technique and specifically relates to a isolator that general type function is strong.
Background
The isolating switch is integrated in the power distribution unit, the double-battery system can be quickly separated to ensure the safety state, the load of all the generators can be borne up to 190A during working, and 100 ten thousand conversion cycles can be completed. The Q-diode in the isolation switch is a power switch that can act independently as a diode. The voltage drop in the conduction direction or EN = high is small and negligible. The Q-diode should be characterized in that the power switch can work like a diode, but does not show a high voltage drop of about 0.7V like a "normal" diode. To enable the diode function, the EN input must be connected to a low voltage. In this mode of operation, the voltage of the Q diode is supplied from T30 or T30Z. The diode function can be ensured by applying a voltage of 8V or more to one of the terminals. If the voltage on the T30 (banister) side is higher than the voltage on the T30Z (starter) side, the MOSFET will turn off and the current is interrupted. When the voltage on the anode (starter) side rises above the cathode level again, the Q-diode becomes conductive (low-ohmic). If a high level is provided to the EN input or an open circuit condition is maintained, the Q diode is in a permanent low ohmic condition regardless of the direction of the flowing current. The power supply for the electronic device comes from T30Z and must be higher than 4.5V. If the voltage is below 4.5V, a plate network can still be provided even on the intrinsic diodes of the mosfets. EN = high supply current is app. 80 muA, absolutely below the common quiescent current requirement of <100 muA. Nevertheless, the low ohmic state of the Q-diode can be guaranteed. The utility model provides a isolator that function is strong even under the vehicle of parking (park heater, amplifier, because the part short circuit, the car emergence accident of parking, the cable is bitten by the animal etc. and the fuse tripping current that arouses), also can ensure high current consumption.
