FZL 4146

The turn-ON threshold at input Dl and ENA can be set via pin TS from 1.5 to 7 V.

VTS = 0 V … 1.5 V

VTS = 1.5 V … 7 V

VTS = VS

Turn-ON threshold = 1.5 V

Turn-ON threshold = VTS

Turn-ON threshold = 7 V

Inputs Dl, ENA and W are proof against line break, i.e. an open input at Dl or ENA

corresponds to input L, open input W corresponds to overcurrent. If input TS is open, the

highest turn-ON threshold is provided.

The internal current supply B and the undervoltage monitor UV ensure that in case of a

supply voltage that is below the VS turn-OFF threshold, outputs Q and SQ are disabled

and the inputs go high-impedance. Basic functioning is possible within the range from VS

turn-OFF threshold to 4.5 V.

In case of overcurrent or short-circuit to ground at any output stage the signaling output

(SQ) will go low. In clock-governed operation (i.e. when there is automatic switching-ON

by the clock and not by a key), SQ goes high and low at the clock rate as long as a short-

circuit or overload is present. SQ is an open-collector output.

Any input and output is ESD proof within the limit values.
