Supply
2.2.1
The logic is supplied with 5 V by the
V
CC
pin, separated from the power stage supply
V
S
.
The advantage of this system is that information stored in the logic remains intact even
in the event of failures in the supply voltage
V
S
. The power supply failure information can
be read out via the SPI. If
V
CC
falls below typically 4.5 V, the logic is shut down, all
internally stored data is deleted and the Output Stages are switched to tristate. The IC is
restarted on rising
V
CC
with a hysteresis of typically 80 mV
After this restart at increasing
V
CC
, or if the device is activated after having been set into
inhibit mode (INH L to H), the IC is initialized by Power-On-Reset (POR). After POR, all
SPI control bits are set to L. This setting remains valid until first SPI communication. Also
the error bits are reset by POR.
Logic Supply Voltage, Power-On-Reset
2.2.2
The power stages are connected to the supply voltage
V
S
. This voltage is monitored by
over voltage (OV) and under voltage (UV) comparators as described in
Section 2.5.6
.
The power supply voltage needs a blocking capacitor to GND.

Direct Inputs
2.3.1
Inhibit (sleep mode)
The INH input can be used to cut off the complete IC. By pulling the INH input to low, the
power stages are switched to tristate, and the current consumption is reduced to just a
few
μ
A at both the
V
S
and the
V
CC
input. It also leads to the loss of any data stored. The
TLE 6209 R is reinitialized with POR if INH is put to high again. The pin has an internal
pull-down.
2.3.2
Disable
The DIS input can be used to disable the output stages. By pulling the DIS input to high
the power stages are switched to tristate, regardless of the signals at the DIR and PWM
inputs. The DIS input can be used as an emergency disable without resetting the SPI
data stored in the IC. It has an internal pull-up.
