Supply

2.2.1

Logic Supply Voltage, Power-On-Reset

The logic is supplied with 5 V by the VCC pin, separated from the power stage supply VS.

The advantage of this system is that information stored in the logic remains intact even

in the event of failures in the supply voltage VS. The power supply failure information can

be read out via the SPI. If VCC 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 VCC with a hysteresis of typically 80 mV

After this restart at increasing VCC, 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.

2.2.2

Power Supply Voltage

The power stages are connected to the supply voltage VS. 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.

2.3

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 ÂµA at both the VS and the VCC 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.
