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 U_Batt
Pin must not be left open but has to be connected either to U_Batt or to V_DD
(e.g. in commercial vehicles)
GND1 to GND8 Ground pins
Ground pins for the power stages (see 2.4)
Ground reference of all logic signals is GND1/2
RST
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
