The L585 is an integrated circuit designed for use
with an NPN darlington as a voltage regulator in a
threephase alternator charging system. It includes
fault diagnostic circuitry which drives a 3 W warning
lamp in fault conditions such as open or short circuit
connections. Protection against load dump tran-
sients, short circuits and low energy spikes is incor-
porated.
