DESCRIPTION

The MP6601 is a stepper motor driver with

parallel inputs and current regulation. Current

sensing is internal and requires no external

sense resistors. High integration and a small

package size make the MP6601 a space-saving

and cost-effective solution for bipolar stepper

motor drives.

The MP6601 operates from a wide supply

voltage of 4.5 - 35V and can deliver motor

current up to 2.5A (depending on thermal

conditions and the package). The MP6601 can

operate a bipolar stepper motor in full-, half-, or

quarter-step modes using internal 2-bit DACs.

Full protection features include over-current

protection (OCP), input over-voltage protection

(OVP), under-voltage lockout (UVLO), and

thermal shutdown.

The

MP6601

is

available

in

QFN-24

(5mmx5mm) and TSSOP-28 EP packages.
