6.7 5A H-Bridge
This FBB represents an H-bridge to drive motor applications such as a latch where a change
in the motor direction is necessary. The FBB is capable of active freewheeling and diagnosis
in on and off state.

6.8 Latch Position Input
This analog input FBB determines the latch state of the inlet connector by measuring the
resistor values representing different latch states (unlocked, locked).
 Meas. range: 1kΩ (unlocked)
11kΩ (locked)
 Pull up resistance: 7.5kΩ
 Accuracy: ± 10%

6.9 20mA LED Output
This LED Output FBB is a constant current LED driver with three channels. Dimming can be
done via PWM up to 200Hz.
 Output current: 20mA
 Switching freq.: static on-off / up to 200Hz
