Features
: 2CHs for current driving-type BTL drivers to drive two-axis actuators
1CH for a voltage driving-type BTL driver for a feed motor
1CH for a voltage driving-type BTL driver for a loading motor
1CH for a voltage driving-type BTL driver for a spindle motor
Use of the HSOP-M36 power package achieves downsizing of the set.
A wide dynamic range
A built-in thermal shutdown circuit installed.
A built-in mute circuit installed. (This circuit can mute the outputs of the drivers
except for those for loading motors.)
The power supplies for PreVcc, the actuator part, the loading part, and PowVcc
of the feed motor part/spindle motor part are provided independently to achieve
an efficient drive.

*1 When mounted on the glass/epoxy board with the size: 70 mm×70 mm, the thickness: 1.6 mm, and
the rate of copper foil occupancy area: 3% or less.
Over Ta=25°C, derating at the rate of 17.6mW/°C.
*2 The power dissipation should be specified within the ASO range.
{ RECOMMENDED OPERATING CONDITIONS
(To determine a power supply voltage, the power dissipation must be taken into consideration.)
