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).

z 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
