"TLE7182EM H-Bridge and Dual Half-bridge Driver IC (Data
6 Half-bridges
Separate, 7 V DC to 32 V DC
One digital output controls the two
switches of a Half-bridge
±5 A rated current (max., per channel)
±7 A short-term current peaks (max.,
per channel)
20 A max. rated current at power sup-
ply plus or minus
20 kHz (max.)
2.5 s (min.)
All 6 Half-bridges together as channel
group to the supply voltage of the
module and to housing
Switch-off at overtemperature, over-
current, short-circuit
Monitoring, fault protection and
switch-off always jointly for two Half-
bridges (channels 1 and 2, channels 3
and 4, channels 5 and 6)
Setting of diagnostics bit at switch-off
Limitation (clamping) of the output
voltage to the external power supply
of the half-bridges
Output-to-ground of voltage supply of
the module:
60 V DC / 30 V AC
Output-to-housing:
60 V DC / 30 V AC
Half-bridge consists of 2 push-pull
switches with current measurement
(current input), diagnostics assembly
Depending on the configuration and
connection as high-side, low-side,
half-bridge switch (Full-bridge through
external connection)
