Overview

The STK6877 is an H bridge power pack reversible brush-type DC motor driver that uses Sanyo’s unique insulated metal substrate technology (IMST) substrate. This technology provides superlative thermal dissipation characteristics. By adopting MOSFET devices as its power elements, this hybrid IC realizes reduced loss and increased current outputs as compared to our earlier STK6860H series.

Features

• Increased margins with respect to rush currents due to the adoption of MOSFET elements

• TTL level compatible inputs

• Support for both two pin control saturation operation and three pin control PWM control

• A braking function is provided.

• Wide operating power supply voltage range (VCC1 = 12 to 42 V)

• Few required external components (Operation is possible with only two external bootstrap capacitors.)

Applications

• Plain paper copier drum and scanner motors

• LBP drum motors

• Printer head carriage motors

• All types of DC motor application equipment
