Full-bridge PWM Motor Driver
SI-5300
September 2005
■General Description
●Two Pch MOSFETs for high side power switches, two Nch for
low side and one control IC are integrated into one package.
●Enables to drive a motor by DC drive at up to 5ADC or by pulse
drive at up to 16A.
●PWM input signal is 20 kHz max, and phase
changeover frequency is 500Hz max.
●Input signals for IN1 and IN2 control the output of
each phase with normal, reverse, brake, and free-run
mode.
●In order to prevent shoot through current during phase changeover,
the control IC set the dead time. Dead time: 20μS (typ).
●Versatile protection functions:
●Over current protection for each power switch (Latch mode)
●Thermal shutdown (TSD)
●DIAG output function: Outputs the diagnosis during abnormal
operation.
■Applications
●Driving various DC motors (PWM control)
●Throttle valve for automotive application
■Features
SI-5300 incorporates two high side Pch MOSFETs, two low side
Nch MOSFETs, and a control IC in one package.
Overcurrent protection function for each power switch, and thermal
shutdown function for control IC. Also, the dead time (20μS) is set
in the control IC to prevent turning on the high side MOSFETs at
the same timing.
