GENERAL DESCRIPTION
FEATURES
The SGM42606 is a motor driver device with one
integrated H-bridge that can run a DC motor, a solenoid,
one winding of a bipolar stepper motor, or other devices.
It can be used in a variety of applications such as
consumer products, toys and other battery-powered
motion-control applications.

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

DETAILED DESCRIPTION
Overview
Bridge Control and Decay Modes
The SGM42606 is a single H-bridge motor driver with
current regulation circuitry. A number of protection
circuits are also provided in the device.
Please refer to the input control logic below on Table 2.
Shoot-through is prevented inside the device, if INxL
and INxH are both high, the high-side and low-side
N-MOSFETs of output will both be off.
The device can operate from 2V to 12V single supply
and has the ability to drive up to 6A peak output
current.

Low On-Resistance,
SGM42606
Single H-Bridge DC Motor Driver
DETAILED DESCRIPTION (continued)
Current Limit Protection
Power Supplies and Input Pins
The current through the motor windings may be limited,
or controlled, by a fixed-frequency PWM current
regulation, or current chopping. For DC motors, current
control is used to limit the start-up and stall current of
the motor. For stepper motors, current control is often
used at all times.
The charge pump is used to generate a gate supply
greater than VCC to turn on the internal N-MOSFETs. A
0.1μF ceramic capacitor is required between VCP and
VCC pins. Connect a 0.1μF capacitor and a 10μF or
larger (ceramic) capacitor between VCC and GND pins
as close to the device as possible.
When an H-bridge and current limit protection function
are enabled, current rises through the winding at a rate
dependent on the DC voltage and inductance of the
winding. If the current reaches the current chopping
threshold, the bridge disables the current until the
beginning of the next PWM cycle. Note that
immediately after the current is enabled, the voltage on
the ISEN pin is ignored for a fixed period of time before
enabling the current sense circuitry. This blanking time
is fixed at 2.5μs. This blanking time also sets the
minimum on-time of the PWM when operating in
current chopping mode.
Device Functional Modes
The nSLEEP is an active low input to put the device in
low-power (sleep mode) state. In sleep mode, all
internal logic, bridges and charge pump are disabled
(stopped).
Protection Circuits
A number of protection features are provided in the
SGM42606 including over-current, under-voltage
lockout, over-voltage protection and thermal shutdown.
Over-Current Protection (OCP)
All switches of the H-bridge are current limit and if an
over-current is detected on one of them, its gate drive
signal is removed. If the current limit persists for a
period longer than the OCP time, all H-bridge
MOSFETs are disabled. The driver will be re-enabled
after the OCP retry period (tRETRY) has passed.
The PWM chopping current is set by a comparator
which compares the voltage across a current sense
resistor connected to the ISEN pins with a reference
voltage. The reference voltage is fixed at 200mV. The
chopping current is calculated in Equation 1.
200mV
ICHOP
=
(1)
Over-current will occur due to an output short to ground,
to power supply, or across the motor windings.
RISENSE
For example, If a 1Ω sense resistor is used, the
chopping current will be 200mV/1Ω = 200mA. Once the
chopping current threshold is reached, the H-bridge
switches slow decay mode. Winding current is
re-circulated by enabling both of the low-side
MOSFETs in the bridge. This state is held until the
beginning of the next fixed-frequency PWM cycle.
Under-Voltage Lockout (UVLO)
If the voltages on VCC pin fall below their under-voltage
lockout threshold, the device will be disabled, and the
internal logic will be reset. Device resumes operation
when all of them go back above their UVLO thresholds.
Over-Voltage Lockout (OVLO)
If the voltages on VCC pin rise more than their
over-voltage lockout threshold, the device will be
disabled. Device resumes operation when power
supply voltage falls back below OVLO thresholds.
The current limit protection function is disabled when
nCLIP_EN = high and enabled when nCLIP_EN = low.
Dead Time
Dead time is used to prevent the crossover during
high-side and low-side MOSFETs switching. The
SGM42606 has a dead time (tDEAD) of about 220ns
(low-side off to high-side on)/170ns (high-side off to
low-side on).
Thermal Shutdown (TSD)
All bridges and drivers are shutdown if a junction over-
temperature occurs in the device. Once the
temperature goes back to the safe level, device
resumes its operation.
