General Description
The IC comprises four driver circuits capable of driving power transistors (PNP or
PMOS). The output transistors are protected against short-circuit to ground and supply
voltage. The turn-ON threshold can be set from 1.5 V to 7 V. Overload at one or several
outputs will be indicated at pin SQ (signaling output). The corresponding power
transistors are then protected by changeover to clock-governed operation.
Circuit Description
Each driver circuit has one active high driver input Dl and a common enable input ENA
(active high) is provided for all stages. The Q output is designed to drive the output
transistors. The load current is sampled and, if necessary, limited via pin W. If the load
current exceeds the preset value, the output stage switches off. Switching-ON again is
provided by the built-in clock generator T. Its operation requires an external capacitor Ce
at pin CE. If Ce is bridged by a break-key, switching-ON can only be carried out by
operating this key. The duty cycle of the clock generator is 1:47 (e.g. 45 µs/2.1 ms with
Ce = 10 nF). The clock generator is privileged versus the current sensor shut down.
When the supply is connected, the internal RS-FF goes into the state corresponding to
the released output.
