Relay-control Output Behavior, Pin 2
Toggle Input, Pin 5
The relay-control output is an open-collector Darlington circuit with an integrated 23-V Z-diode
for limiting the inductive cut-off pulse of the relay coil. The maximum static collector current must
not exceed 300 mA and the saturation voltage is typically 1.1 V at 200 mA.
The lC supply is protected by R
by a series resistor, integrated Z-diode and RF capacitor (refer to
The relay-control output is protected by the integrated 23 V Z-diode in case of short interference
peaks. It is switched to conductive condition for a battery voltage greater than 40 V in case of
load dump. The output transistor is dimensioned so that it can withstand the generated current.
When the operating voltage is switched on, an internal power-on reset pulse (POR) is generated
which sets the logic of the circuits to a defined initial condition. The relay output is disabled.
The time functions (relay output) can be started or interrupted by the three inputs ON, OFF or
TOGGLE (pins 3, 4 and 5, input circuit of these pins see
