2.4
The output stages consist of a DMOS H-bridge built by two highside switches and two
lowside switches. Integrated circuits protect the outputs against overcurrent and
overtemperature if there is a short-circuit to ground or 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.
2.4.1
To realize the fast switching times, the charge pump, which generates the voltage
necessary to switch on the n-channel D-MOS high-side switches, must be highly
efficient. It requires an external capacitor
pump buffer input, DRV. It should be placed as close to the pins as possible.
2.4.2
To limit the output current, a chopper current limitation is integrated as shown in
Figure 3. The current is measured by sense cells integrated in the low-side switches. As

2.4.3
When drivng inductive loads with PWM operation, the dissipated power can be
significantly reduced by activating the transistor located parallel to the internal
freewheeling diode. This is realized in the TLE 6209 R. When switching an output from
L to H, the high-side switch is turned on after a certain dead-time to avoid cross currents
flowing through the half bridge.
