TLE 6244X

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

Clock for the µsec-bus (pin shared with IN16)

FDA

Data for the µsec-bus (pin shared with IN6)

SSY

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

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
