DRIVER COLLECTOR
INPUT
The collector current for the internal driver which drives the external
darlington is supplied through this pin. The external resistor R10 limits the
dissipation in the IC. The value this resistor depends on the darlington used
and on the limiting current in the coil.
15
OVERVOLTAGE
LIMITATION
The external darlington is protected against overvoltage by means of an
internal zener available at this pin. The external divider R5/R6 defines the
limitation value, typically given by :
Vovp
=

R5
+ 5 103
R6
+ 30
16
DRIVING STAGE
OUTPUT
Current Driver for the External Darlington. To ensure stability on the current
limitation loop a capacitor C3 (typically 2.2nF, this value depending on the
darlington used) must be connected between this pin and the current
sensing input (pin 1).
