MC34933EP中文资料H-Bridge, Dual, Low Voltage, Stepper & DC Brushed Motor Driver, 2-7V, 1.4A, 200kHz, QFN 16数据手册恩XP规格书

描述 Description

The NXP® MC34933 is a two channel H-Bridge driver with a variety of applications, such as auto focus control, that make it ideal for the digital camera market.
Uses the NXP proprietary SMOS8 Bi CMOS process to deliver a low power device with a maximum quiescent current of 100uA for the motor drive supply and 400uA for the control logic supply
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
Thermal protection circuitry for the H-Bridge drivers to avoid damage to the IC's internal Power MOSFET circuitry
