AM9268Q

The AM9268Q is 8-Channel motor driver IC which has 2 Channel PWM drivers for sledge

motor, 2 Channel BTL drivers for collimator motor, 3 channel actuator drivers and 1 tray driver.

The PWM control system for sledge is used to reduce IC power dissipation. This IC also has

1 independent precision voltage regulator with enable control. Output voltage adjustable

range is from 1.2V to 4.0V.It has built-in thermal-shut-down circuit. Package material is Pb

free.
