motor driver SS8833T
DESCRIPTION
The SS8833T is a dual bridge motor driver which has two H-bridge drivers, and can drive two DC brush motors, a bipolar stepper motor, solenoids, or other inductive loads. It operates from 2.7V to 16V, and can deliver load current up to 1.0A per channel. The output driver block of each H-bridge consists of P+N-channel power MOSFETS configured as an H-bridge to drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current. The internal safety features include sinking and sourcing current limits implemented with external sensors, under-voltage lockout, over current protection (OCP) and thermal shutdown. An over-temperature output flag is available to indicate thermal shutdown. The SS8833T is packaged in 16-pin, 5.0mm×6.4mm eTSSOP with an exposed thermal pad on the back.
FEATURES
Wide Power Supply Voltage Range: 2.7V to 16V
Two Internal Full-Bridge Drivers
Low Quiescent Current: 1.1mA
Low Sleep Current: 1μA
Thermal Shutdown and Under-Voltage Lockout Protection
Over Current Protection (OCP)
Over-Temperature Output Flag
Thermally-Enhanced Surface-Mount Package
Low MOSFET On Resistance (HS: 650mΩ; LS: 350 mΩ
APPLICATIONS
POS Printers Video Security Camera Robotics Battery Powered Toys
