Freescale Semiconductor Technical Data 5.0 A Throttle Control H-Bridge The 33926 is a SMARTMOS monolithic H-Bridge Power IC designed primarily for automotive electronic throttle control, but is applicable to any low-voltage DC servo motor control application within the current and voltage limits stated in this specification. The 33926 is able to control inductive loads with currents up to 5.0 A peak. RMS current capability is subject to the degree of heatsinking provided to the device package. Internal peak-current limiting (regulation) is activated at load currents above 6.5 A 1.5 A. Output loads can be pulse width modulated (PWM’ed) at frequencies up to 20 kHz. A load current feedback feature provides a proportional (0.
