Overview
The STK681-050 is a bidrectional DC brush-type motor
driver IC with brake function that incorporates MOSFET
power elements.
Applications
• PPC drum and scanner motor drivers
• LBP drum motor drivers
• Printer head and carriage motor drivers
• General DC motor applications
Features
• H-bridge output stage configuration employing 4
MOSFETs
• Independent TTL/CMOSlev el control for each MOSFET
(4-pin control)
• External signal control of forward, reverse and brake
opreration
• MOSFETs supporting 12A peak starting current and
13.5A peak brake current (F3 and F4 ON)
• DC input supporting saturation operation
• Only 1 charge pump electrolytic capacitor required, compared with the STK6875 which requires 2
