Part Number: AM5810
Function: Quad BTL Power Driver
Package: HSOP-28 Type
Manufacturer: Amtek Semiconductors
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).
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 z Absolute Maximum Ratings Parameter Supply voltage Power dissipation Operating temperature Storage temperature Symbol PREVCC, POWVCC Pd Topr Tstg Limits 13.5 1.7- -40 ~ +85 -55 ~ +150 Unit V W ℃ ℃ *On less than 3% (percentage occupied by copper foil), 70 x 70mm2, t = 1.6mm, glass epoxy mounting. Reduce power by 13.5mV for each degree above 25℃.
