Input Mapping Rgister (MAP)
Defined to which outputs the IN4 / IN is assigned (can be one up to all)
0.. No connection to IN4 / IN
1.. Output can be controlled with IN4 / IN pin
Boolean operation Register (BOL)
The logic operation for serial and parallel control signal is defined for all channels individually
0.. Logic "OR"
1.. Logic "AND"
Overload Behavior Rgister (OVL)
The overload behavior of a single channel is defined.
0.. Current limit without shutdown of the channel
1.. Current limit with latching overload shutdown of the channel
Overtemperature Behavior Register (OVT)
The overtemperature behavior of a single channel is defined.
0.. Autorestart after cooling down
1.. Latching shutdown on overtemperature
Switching Speed / Slew Rate Register (SLE)
The switching speed of the channels is defined
0.. fast (10µs)
1.. slow (50µs)
Output State Register (STA)
Reads back the state of the output (read only register)
0: DMOS off
1: DMOS on
Serial Output Control Register (CTL)
Sets the serial controll bits for switching the output stages.
0: Output off
1: Output on
SPI Diagnostics:
As soon as a fault occurs for longer than the fault filtering time, the fault information is latched into the
diagnosis register (and the Fault pin will change from high to low state). A new error on the same
channel will over-write the old error report. Serial data out pin (SO) is in a high impedance state when
CS is high. If CS receives a LOW signal, all diagnosis bits can be shifted out serially. If the sent com-
