MC33926 5.0 A throttle control H-bridge Rev. 16 19 February 2020 Data sheet: technical data 1 General description 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. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified. 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 (PWMed) at frequencies up to 20 kHz. A load current feedback feature provides a proportional (0.24 % of the load current) current output suitable for monitoring by a microcontrollers A/D input. A status flag output reports undervoltage, overcurrent, and overtemperature fault conditions. Two independent inputs provide polarity control of two half-bridge totem-pole outputs. Two independent disable inputs are provided to force the H-bridge outputs to tri-state (high-impedance off state). An inverted input changes the IN1 and IN2 inputs to low (true logic). 2 Simplified application diagram V DD V PWR VPWR SF FB CCP IN1 OUT1 IN2 INV MCU 33926 motor SLEW OUT2 D1 D2 PGND EN AGND aaa-028113 Figure 1.Simplified application diagram 3 Features and benefits 5.0 V to 28 V continuous operation (transient operation from 5.0 V to 40 V)NXP Semiconductors MC33926 5.0 A throttle control H-bridge 225 m maximum R at 150 C (each H-bridge MOSFET) DS(on) 3.0 V and 5.0 V TTL/CMOS logic compatible inputs Overcurrent limiting (regulation) via an internal constant-off-time PWM Output short-circuit protection (short to V or ground) PWR Temperature dependent current limit threshold reduction All inputs have an internal source/sink to define the default (floating input) states Sleep mode with current draw < 50 A (with inputs floating or set to match default logic states) AEC-Q100 grade 1 qualified 4 Applications Electronic throttle control (ETC) Exhaust gas recirculation (EGR) Turbo flap control Industrial and medical pumps and motor control 5 Ordering information This section describes the part numbers available to be purchased along with their differences.
