The TLE9202ED contains two independent general purpose 6 A H-Bridges in one Package. It is designed for (but not limited to) the control of DC motors or other inductive loads in automotive applications. The outputs can be pulse width modulated at frequencies up to 20 kHz. PWM/DIR control reduces the number of PWM capable pins needed on the microcontroller side. For load currents above the current limitation threshold (8 A typ.) the H-Bridge goes into chopper current limitation mode. It is protected against short circuits and overtemperature and provides extensive diagnosis via SPI or basic error feedback via error flag. Open load can be detected when the bridge is disabled or during PWM operation of inductive loads.
