1.5 Function of Pins
IN1 to IN16
Control inputs of the power stages
Internal pull-up current sources (exception: IN8 with pull-down current
source)
FCL
FDA
SSY
Clock for the µsec-bus (pin shared with IN16)
Data for the µsec-bus (pin shared with IN6)
Strobe and Synchronisation for the µsec-bus (pin shared with IN7)
OUT1 to OUT18
Outputs of the power switches
Short-circuit proof
Low side switches
Limitation of the output voltage by zener diodes
VDD
Supply voltage 5V
UBatt
Supply voltage UBatt
Pin must not be left open but has to be connected either to UBatt or to VDD
(e.g. in commercial vehicles)
GND1 to GND8
RST
Ground pins
Ground pins for the power stages (see 2.4)
Ground reference of all logic signals is GND1/2
Reset
Active low
Locks all power switches regardless of their input signals (except OUT8)
Clears the fault registers
Resets the µsec-bus interface registers
ABE
In-/Output VDD-Monitoring
Active low
Output pin for the VDD-Monitoring
Input pin for the shut-off signal coming from the supervisor
GND_ABE
Sense ground VDD-Monitoring
SI, SO, SCK, SS SPI Interface
