Description

SI-6633M is a 3-phase brushless motor driver IC, with rated current of 2A(DC)/4A(peak)
Output DMOSFET, pre-drive, PWM current control, and protection functions are integrated into a single package. The device supports motor power voltage up to 30V.

Application

Printers, industrial equipment

Features

Motor supply voltage range VBB=10~30V
Output DMOSFETs are integrated. Output current IOUT=2A(DC)/4A(peak)
Hall Input
Current control function
Fixed frequency PWM (Internal PWM) with peak current control
PWM control by speed control signal with analog voltage (External PWM)
PWM control by logic input (Logic PWM)
Over current protection
Over voltage protection
Thermal shutdown
Under voltage lock out
Motor lock detection
*Alarm output pin (FLAG) is active when any protection is activated.
Motor speed output by hall input transition (FG)
Synchronous rectification with low power dissipation
Select for synchronous rectification (active/passive).
Stand-by mode
*Although the device may be protected from damaged with protection circuit in the device from design point of view, it can’t be guaranteed the device being damaged by the protections in the device. In the design of set, please take care to avoid abnormal condition with all the countermeasures you can take.
