Application
TLE6282G
• _{Dedicated for DC-brush high current motor bridges in PWM control mode and adapted for use in injector and}
valve applications for 12, 24 and 42V powernet applications. Useable as four fold lowside driver for unipolar 4
phase motor drives.
• _{The two half bridges can operate independently. The two half bridges can even operate at different supply}
voltages.
