IFX9201SG
6 A H-bridge with SPI diagnosis
IFX9201SG is a general purpose 6 A H-bridge. It is designed for the control of small DC
motors and inductive loads.
Key features
››R (typ) = 100 mΩ per switch
››Operation voltage 5.0 V to 36.0 V
››3.3 V and 5.0 V compatible logic
DS(on)
Based on the automotive know-how, the IFX9201SG is optimized for non automotive
applications such as industrial applications, home appliances and building automation,
power tools battery management and electric toys.
The outputs can be pulse width modulated at frequencies up to 20 kHz by means of
PWM/DIR control. While the signal at the DIR input defines the direction of the DC motor,
the PWM signal controls the duty cycle. PWM/DIR control reduces the number of PWM
capable pins needed at the microcontroller.
inputs (TTL/ CMOS)
››Low stand-by current
››Short circuit and overtemperature
protection
››V undervoltage shutdown
››Open load detection in ON and OFF
S
state
For load currents above the current limitation threshold (8 A typ) the H-bridge switches
into chopper current limitation mode.
The IFX9201SG is protected against short circuits and over temperature and provides
diagnosis via SPI or basic error feedback via status flag. Open load can be detected when
the bridge is disabled or during PWM operation of inductive loads.
The robust PDSO-12 package provides excellent thermal performance due to the thick
copper heat slug and is well suited for automatic optical solder inspection.
Applications
››DC motor control for industrial applications
››Home and building automation
››Power tools battery management
››Industrial robotic applications
››Electric toys
