H-Bridge Motor Driver, 2-7 V, 1.4 A, 200 kHz
- このページには、製造中止（生産終了）となった製品の情報が記載されています。本ページに記載されている仕様および情報は、過去の参考情報です。
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 100 uA for the motor drive supply and 400 uA 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 1u A to extend battery life
Thermal protection circuitry for the H-Bridge drivers to avoid damage to the IC's internal Power MOSFET circuitry
