NXP Semiconductors MC33926 ICs & Drivers
NXP Semiconductors MC33926 ICs and Drivers are SMARTMOS monolithic H-Bridge Power ICs designed primarily for automotive electronic throttle control. These NXP ICs apply to any low-voltage DC servo motor control application within the current and voltage limits. The MC33926 drivers feature overcurrent limiting via an internal constant-off-time PWM and output short-circuit protection. These ICs include temperature-dependent current limit threshold reduction. The MC33926 drivers operate at a 5V to 28V voltage range. These drivers are ideal for electronic throttle control (ETC), exhaust gas recirculation (EGR), and turbo flap control.
