Quad BTL Power Driver AM5810
The AM5810 is a 4-channel BTL driver - 2 channels are able to use for stepping motor, and 1 channel is for reversible driver - designed to be used with ordinary electronic equipment (such as audio-visual equipment, office automation equipment, communications devices, electrical appliances, and electronic toys).
Applications
CD players
Features
1) A power saving mold is enabled by power-saver terminal. 2) Small surface mounting power package (HSOP-28) 3) Separating Vcc into Pre and Pow, can make better power efficiency 4) Thermal-shut-down circuit built in 5) Wide dynamic range 4.OV (Typ.) at PreVcc=12V, PowVcc=5V 6) BTL driver: Input pins consist of (+) and (-), therefore various input types are available such as differential input. 7) Loading driver: a. The output voltage is adjustable by output voltage control terminal. (Only "H" side voltage) b. Brake circuit built in c. Circuit protection diode built in
