Chip Introduction
The SS6811E offers a dual-channel integrated motor drive solution for stage lighting and other motor integration applications.
The SS6811E has two H-bridge drivers, each delivering a maximum output current of 1.6A (at 24V and Ta = 25°C with proper heat dissipation), and can drive two brush DC motors, or a bipolar stepper motor, or solenoids, or other inductive loads. The power delivery module for each H-bridge of the SS6811E consists of N-type power MOSFETs.
The SS6811E provides a low power sleep mode to shut down internal circuitry to achieve very low quiescent current. This sleep mode is implemented by setting the SLEEP pin. Internal shutdown includes overcurrent protection, short-circuit protection, undervoltage lockout protection, and overtemperature protection.
The SS6811E is available in a 16Pins, 5.0mm * 6.4mm, eTSSOP package with exposed pads for improved heat dissipation, and is lead-free with 100% tin-free leadframe plating.
