The IFX9202ED is a dual general purpose 6A H-bridge for industrial applications, home appliance and building automation, power tools battery management and medical applications, designed for the control of small DC motors and inductive loads is available from Infineon. The outputs can be pulse width modulated at frequencies up to 20kHz - that enables operation above the human sonic range - by means of PWM/DIR control. While the signal at the direction input defines the direction of the DC motor, the PWM signal controls the duty cycle. For load currents above the current limitation threshold (8A typ.) the H-Bridge switches into chopper current limitation mode. The IFX9202ED is protected against short circuits and over temperature and provides diagnosis via SPI or basic error feedback via status flag. Open load can be detected when the bridge is disabled or during PWM operation of inductive loads. The robust PG-DSO-36-72 package provides excellent thermal performance.
