Features
* Dual power supply voltage design (5/12V) and wide voltage handling range * Built-in Hall amplifier with hysteresis (supports core without auxiliary electrode) * Built-in lockup protection and automatic recovery circuits (External capacitor for rotation detection need only be 0.1 F, allowing compact, cost-saving design) * Built-in FG output (Vosat = 0.2Vtyp at IO = 5 mA) * Built-in output transistor with output withstand voltage 24Vmin/output current 500 mA (average), 1.2A (peak) * Built-in thermal protection circuit * Compact, high-temperature resistant MFP-10 package reduces external parts count and mounting space, therefore making this IC support the motors with a wide range of sizes and speeds.

Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.

Precautions * Wiring layout for IN- and OUT1 must be designed to prevent interference. * If the wiring between the Hall element and the IC input is long, noise interference may lead to chattering in the FG output waveform. In this case, insert a capacitor with 0.01 to 0.001 F between IN+ and IN-. * If CT pin is connected to GND, the lockup protection and restart functions are disabled. * In a circuit configuration as shown above, a current-GND reverse connection will cause a current to flow as follows: GND -> OUT -> coil -> power supply. The magnitude of this current is limited by the coil resistance. If it is less than 500 mA, the IC will not be destroyed. If required, insert a diode between VCC and the coil.

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
