The TLE8209-2SA contains four n-channel power-DMOS transistors that can be used in an H-bridge or in dual
half bridge configuration.
Integrated circuits protect the outputs against overcurrent and over-temperature, in case of short-circuit to ground,
to the supply voltage or across the load. Positive and negative voltage spikes, which occur when switching
inductive loads, are limited by integrated freewheeling diodes (body diodes of power-DMOS).
7.1
By default the setting of the power switches is controlled by the Inputs IN1, IN2 (parallel control). The outputs
OUT1 and OUT2 are set to High (high-side switch ON, low-side switch OFF) or Low (high-side switch OFF, low-
side switch ON) by the parallel inputs IN1 and IN2, respectively. In SPI mode there is also the option to control the
outputs via the SPI bits SIN1 and SIN2 of the SPI configuration register. To switch to SPI control the bit MUX has
to be set to ’0’.
In addition, the outputs can be disabled (set to tristate, high- and low-side switch OFF) by the disable input DIS
and the bidirectional reset pin ABE. Disabling sets the device to parallel control
