The TLE8102SG is supplied by power supply line V
device including the gate control of the power stages. A capacitor between pins V
The TLE8102SG can be programmed via SPI to enter sleep mode. In sleep mode, all outputs are turned off and
all diagnosis and biasing circuits are disabled. These actions reduce the quiescent current consumption from the
power supply. However, the SPI configuration registers (except for the channel on/off register) are not reset when
the TLE8102SG enters sleep mode. To exit sleep mode, a wake up command must be sent via SPI.

5.2
There are two input pins available on the TLE8102SG to control the output stages.
Each input signal controls the output stages of its assigned channel. For example, IN1 controls OUT1 and IN2
controls OUT2. Please refer to
pull-down current source. A comparator with hysteresis determines the state of the signal on INn. The zener diode
protects the input circuit against ESD pulses.
The BOL bit can be set via SPI. This bit determines if the output is exclusively controlled by the INn signals,
exclusively controlled by the corresponding data bits CHn
inputs. The default setting of the BOL bits programs the outputs to be controlled exclusively by the INn signals.
The SLEn bit can be set via SPI. This bit sets the slew rate of its assigned channel by selecting either slew rate 1
or slew rate 2. The slew rate also changes the over load switch off delay time (only for current limit 2).
