SGM42540
Single H-Bridge DC Motor Driver
GENERAL DESCRIPTION
FEATURES
The SGM42540 is an integrated driver IC for driving
● Motor Supply Voltage Range: 8V to 45V
one brushed DC motor in industrial applications. The
device operates from a single power supply and
supports a wide input supply range from 8V to 45V.
● Single H-Bridge Motor Driver
● 5-Bit Current Control Supports up to 32 Current
Levels
● 4.5A Peak Output Current at VM = 24V, TJ = +25℃
● Built-in 3.3V Internal Reference
● Parallel Digital Control Interface
● Full Set of Protections
The PHASE and ENBL pins allow simple interfacing to
controller circuits. The device has one H-bridge driver
for driving a DC motor.
With proper heatsinking, the SGM42540 can deliver up
to 4.5A peak or 3.5A continuous output current (at VM =
24V and TJ = +25℃). Five input pins (ISET0 - ISET4)
are used for 32 current levels. The decay mode (slow
or fast) can be selected by DECAY pin.
Over-Current Protection (OCP)
Under-Voltage Lockout (UVLO)
Thermal Shutdown (TSD)
Active-Low Fault Indication Pin (nFAULT)
● Available in a Green TSSOP-28 (Exposed Pad)
Package
A number of protection features are provided in the device
including over-current, short-circuit, under-voltage lockout
and thermal shutdown.
APPLICATIONS
The SGM42540 is available in a Green TSSOP-28
(Exposed Pad) package.

Package Thermal Resistance
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended

ESD Susceptibility
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

Current Set Reference Voltage Input. Apply the reference voltage to set the winding current value.
These pins should be tied together on the PCB.
Active-Low Reset Input. Active-low reset with weak internal pull-down to initialize logic and disable
H-bridge outputs.
Active-Low Sleep Mode Input. Active-low logic input with weak internal pull-down. Apply high to
enable device, and low to enter into the low-power sleep mode.
Decay (Brake) Mode Selection Input. Low = slow decay (brake), high = fast decay (coast). Internal
pull-down and pull-up.
