mc34933

NXP mc34933 two channel H-Bridge driver is aimed at the digital camera market. mc34933 uses NXP's proprietary SMOS8 Bi CMOS process to deliver a low power device, with a maximum quiescent current of 100μA for the motor drive supply and 400μA for the control logic supply. This device has four operation modes: forward, reverse, brake, and tri-state (high-impedance). The 34933 employs a VCC detection circuit to sense when the logic supply switches to an off-state with a maximum current of 1uA to extend battery life.

mc34937a

NXP's mc34937a Three Phase Field Effect Transistor Pre-Driver is designed for three-phase motor control and similar applications. The integrated circuit (IC) uses SMARTMOS technology. The IC contains three high side FET pre-drivers and three low side FET pre-drivers. Three external bootstrap capacitors provide gate charge to the high side FETs. The IC interfaces to a MCU via six direct input control signals, an SPI port for device setup and fault detection, an asynchronous reset, an interrupt and two enable signals. Both 5.0 and 3.0V logic level inputs are accepted and 5.0 V logic level outputs are provided.
