MP6601
35V, 2.5A, Stepper Motor Driver
The Future of Analog IC Technology
DESCRIPTION
FEATURES
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.
Wide 4.5V to 35V Input Voltage Range
Two Internal Full-Bridge Drivers
Internal Current Sensing and Regulation
Low On Resistance (HS: 170mΩ, LS:
150mΩ)
No Control Power Supply Required
Simple PHASE/I0/I1 Logic Interface
3.3V and 5V Compatible Logic Supply
Step Modes from Full-Step to Quarter-Step
2.5A Output Current
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.
Automatic Current Decay
Over-Current Protection (OCP)
Input Over-Voltage Protection (OVP)
Function
Thermal Shutdown and Under-Voltage
Lockout (UVLO) Protection
Full protection features include over-current
protection (OCP), input over-voltage protection
(OVP), under-voltage lockout (UVLO), and
thermal shutdown.
