PRODUCT OVERVIEW The SS8844T offers four independently controlled 1/2 H-bridge starters.
It can be used to drive two DC motors, a stepper motor, four solenoids, or other loads.
The output driver channel for each channel consists of an Nchannel power MOSFETs configured in a 1/2 Hbridge configuration.
The SS8844T delivers up to 2.5A peak current or 1.75A root mean square (RMS) output current (with appropriate printed circuit board (PCB) heat dissipation at 24V and 25°C) on each bridge channel.
The
SS8844T Features
* Dual channel H-bridge current control motor driver - Single or two brushed DC motors
* One stepper motor - Fully independent half-bridge control
* Industry standard IN/IN digital control interface
* Metal oxide semiconductor field effect transistor (MOSFET) with low on-impedanc
