Type FZL 4146 G General Description
Ordering Code Q67000-H8743
Package P-DSO-20-7 (SMD)
The IC prises 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 mon 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....
