Freescale Semiconductor Technical Data Document Number: MC34933 Rev. 3.0, 9/2014 1.4 A Dual H-Bridge Driver Compatible with 3.0 V Logic 34933 The 34933 is a two channel H-Bridge driver aimed at the digital camera market. There are a variety of applications containing bipolar step motors and/or brush DC motors, such as Auto Focus control for the digital camera lens. The 34933 uses Freescale's proprietary SMARTMOS process to deliver a low-power device, with a maximum quiescent current of 100 A for the motor drive supply and 400A for the control logic supply. H-BRIDGE DRIVER The 34933 VM supply operates from 2.0 V to 7.0 V using an internal charge pump, with independent control of each H-Bridge driver via the MCU (IN1A, IN1B, IN2A, IN2B). The 34933 has a low total RDS(on) of 1.
