DESCRIPTION
The CRM2463 is a motor driver designed for 2 phase
stepping motor, it implement PWM to regulate output
current. The driver stage is consists by dual MOSFET H-
bridge. Fabricated by advanced BCD process to improve
performance and reduce power losses. The driver support
up to 40V supply voltage and maximum driving current up
to 1.8A.
The on-chip voltage regulator allows only powered from a
single power supply, VM, it highly reduce external
components and saving the PCB size.
APPLICATIONS
Home appliance
Amusement machine
Office automation machine
