|2ch H-Bridge Small Motor Driver, 6 to 18V Single Power Supply Driving, 0.7A|
|Home Appliances, Consumer Electronics|
Asahi Kasei Microdevices Corporation, (AKM), has developed a motor driver, the AP1010AEN, capable of operation with a single 18V power supply. The AP1010AEN is ideal for 12V systems such as home equipment, (e.g. opening/closing water heater valves), and white goods household appliances, (e.g. refrigerators and ice machines). Since operating temperature of the overvoltage protection circuit and operating current of the overcurrent protection are optimized, the AP1010AEN can have a circuit configuration that removes a fuse from the motor’s power supply line while keeping motor operation safe. The AP1010AEN is capable of driving two DC motors, or one stepping motor.
The AP1010AEN has undervoltage protection, overcurrent protection and thermal protection functions. Reliability is improved by optimizing these detection thresholds. Therefore, it is possible to design a system that shuts down in abnormal situations, such as during a short circuit. This allows removing a protective fuse from the motor power supply line. In addition, overcurrent protection can be disabled using external signals, enabling to avoid malfunction caused by inrush current or regenerative current when starting or stopping a motor.
The AP1010AEN is housed in a 16-pin 3 mm × 3 mm QFN package.
