Motor chip


SS8833T is designed for smart home and printer built-in over current over temperature under voltage protection of 2-channel stepper motor drive/dual brush drive chip support dual lithium battery power supply

Chip Introduction

The SS8833T is a dual-bridge motor driver with two H-bridge drivers that can drive two DC brushed motors, a bipolar stepper motor, solenoids, or other inductive loads. It operates from 2.7V to 15V and can draw up to 1.0A of load current per channel. The output driver block of each H-bridge consists of P+N-channel power MOSFETs configured as H-bridges to drive the motor windings. Each H-bridge includes circuitry that regulates or limits the winding current. Internal safety features include the use of external current-limiting resistors for output current limiting, undervoltage lockout, overcurrent protection (OCP), and overtemperature protection shutdown. Overtemperature output alarm, which can be used to indicate thermal shutdown.

 The SS8833T is available in three packages for customer flexibility.
