SGM42610/SGM42611
Stepper Motor Driver ICs
GENERAL DESCRIPTION
FEATURES
The SGM42610/SGM42611 can drive solenoids, two
DC motors, one DC motor in parallel connection, as
well as a stepper motor in full-step or half-step. The
devices can operate over a wide input voltage range of
2.5V to 16V.
● SGM42610: Quad Half-Bridge Driver
● SGM42611A: 4-Wire Input Stepper Driver
● SGM42611B: 2-Wire Input Stepper Driver
● Supply Voltage Range: 2.5V to 16V
● Integrated Protection Features
VCC Under-Voltage Lockout (UVLO)
Over-Current Protection (OCP)
Thermal Shutdown (TSD)
Two versions (SGM42611A and SGM42611B) of the
SGM42611 are offered. The SGM42611B has low
power sleep mode which is provided to save power
dissipation. If the EN pin is pulled low, the SGM42611B
Short-Circuit Protection (SCP)
Auto-Retry
will enter into sleep mode after tSLEEP
.
● Low Power Sleep Mode (SGM42611B Only)
● Available in Green MSOP-10 (Exposed Pad) and
SSOP-10 Packages
The SGM42610 and SGM42611 are available in Green
MSOP-10 (Exposed Pad) and SSOP-10 packages.

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.

DETAILED DESCRIPTION
IN/FAULT Operation
Over-Current Protection (OCP)
For SGM42610/11A, IN4/FAULT is an enable input or
alert output pin. If this pin is pulled high more than tFAULT
it can be used to alert output; in other cases, this pin is
just as logic input controls state of OUTx.
An analog current limit circuit on each MOSFET limits
the current through the MOSFET by limiting the gate
drive. If this analog current limit persists for longer than
the OCP deglitch time (tOCP), all MOSFETs in the
H-bridge will be disabled and the FAULT pin will be
driven low. The driver will be re-enabled after the OCP
retry period (tRETRY) has passed. If the fault condition is
still present, the cycle repeats. If the fault is no longer
present, normal operation resumes and the FAULT pin
becomes high again after 2ms. Please note that only
the H-bridge in which the OCP is detected will be
disabled while the other H-bridge will function normally
(OUT1 and OUT2 form an H-bridge, OUT3 and OUT4
form another H-bridge).
,
For SGM42611B, the FAULT is a separate fault flag pin.
When OCP or TSD occurs, the FAULT pin will be driven
low.
Under-Voltage Lockout (UVLO)
If at any time, the voltage on the VCC pin falls below
the under-voltage lockout threshold, all output drivers
are disabled, and all internal logic will be reset.
Operation will resume when VCC rises above the UVLO
threshold. The FAULT pin is not driven low in the event
of an under-voltage condition.
Over-current conditions are detected independently on
both high-side and low-side devices. For example, a
short across the motor winding will all result in an
over-current shutdown.
EN Operation
The EN pin of SGM42611B is an enable or sleep mode
input. When the EN pin is logic low for less than tSLEEP
,
Thermal Shutdown (TSD)
all output drivers are disabled, as shown in Table 3.
After the EN pin is pulled low more than tSLEEP, the
device will enter into a low power sleep mode. In this
state, the output drivers are disabled, all internal logic is
reset, and internal clocks are stopped. All inputs are
ignored until EN returns inactive high. The internal
pull-down resistor of EN pin is approximately 100kΩ.
The FAULT pin is not driven low in the event of a low
power sleep mode.
If the die temperature exceeds safe limit, all output
drivers are disabled and the FAULT pin will be driven
low. Once the die temperature has fallen to a safe level
operation will automatically resume.
