Description of the Power Stages
4 low side power switches for nominal currents up to 3A (power stages OUT1 to OUT4). Con-
trol is possible by input pins or via SPI. For T
switches is below 500mΩ.
2 low side power switches for nominal currents up to 1.5A (power stages OUT5 and OUT6).
Control is possible by input pins or via SPI. For T
switches is below 1Ω.
In order to increase the switching current or to reduce the power dissipation parallel connec-
tion of power stages is possible.
Each of the 6 output stages is equipped with an own zener clamp, that limits the output volt-
age to a maximum of 60V. The outputs are provided with a current limitation set to a minimum
of 1.5A resp. 3A. Each power stage is equipped with an own temperature sensor.
Each output is protected by embedded protection functions
circuit to U
(early warning). If this operation leads to an overtemperature condition, a second protection
level (about 170°C) will change the output into a low duty cycle PWM (selective thermal shut-
down with restart) to prevent critical chip temperatures.
The following faults can be detected (individually for each output):
- short to UBatt:
- short to ground:
- open load:
- overtemperature: (OT) will only be detected when switches are
The fault conditions SCB, SCG and OL will not be stored until an integrated filtering time is
expired (please note for PWM application). If, at one output, several errors occur in a se-
quence, always the last detected error will be stored (with filtering time). All fault conditions are
encoded in two bits per switch and are stored in the corresponding SPI registers. Additionally
there are two central diagnostic bits: one especially for overtemperature (latched result of an
OR-operation out of the 6 signals of the temperature sensor) and one for fault occurrence at
any output. A fault that has been detected and stored in the fault register must not be replaced
by o.k.-state (11) unless it is read out by the RD_DIAG command sent by the microcontroller
or an internal or external reset has been applied. I.e. the fault register will be cleared only by
the RD_DIAG command.
PRG - Program pin.
If the parallel input pins are not connected (independent of high or low activity) it is guaranteed
that the channels 1 to 6 are switched OFF.
PRG pin itself is internally pulled down when it is not connected.
