Type FZL 4145 D General Description
Ordering Code Q67000-H8437
Package P-DIP-18-1
The IC prises four driver circuits capable of driving power transistors for high output currents. The output transistors are protected against short-circuit to ground and supply voltage. The input threshold can be adjusted between 1.5 V and 7 V. Overload or shortcircuit failure at an output will be indicated at pin SQ (signaling output). Functional 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) outputs are designed to drive the output transistors. The load current is sampled 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. Its operation...
