FUNCTIONAL DESCRIPTION
The SGM42622B is a low voltage stepper motor driver
Figure 4 shows how the step mode is selected for the
SGM42622B with some examples.
that includes
a
10-bit sequencer with 1/256
microstepping capability, two PWM current controllers
and two protected full-bridges in power stage.

This device can be placed in standby mode to reduce
the power consumption to near zero by pulling the
STBY/RESET input pin below the VSTBYL threshold.

In standby mode, the supply current of the controller is
significantly reduced and the power stage is shutdown
with outputs in a high-impedance state.

Figure 4. Mode Selection Examples
The 4-bit binary value on the MODEx inputs is latched
just after power-up or when the device exits standby
mode. In normal operation, the input value is ignored
and the MODE3 and MODE4 inputs act as step clock
(STCK) and direction (DIR) inputs. The only exception
is when MODE1 and MODE2 are both at low state. In
such condition, the latched value is ignored and the
device operates in full-step mode. If either MODE1 or
MODE2 input returns to high state, the previous
operating mode will be restored.
The sequencer is a 10-bit counter used to set the PWM
current controller’s reference and H-bridge current
direction. The counter resets to zero after power-up or
standby and is counted with each rising edge of STCK.
It is increased if DIR = high or decreased if DIR = low.
The current direction and references that determine the
output currents of the device as listed in Table 2 for
full-step mode. VREF is the reference input (0.1V to 0.5V
recommended) to adjust the output current magnitudes.
The values for other step modes are listed in Table 2.

Table 3 lists the reference and sequencer values for 1/2,
1/4 and 1/8 step modes. For higher microstepping
resolutions, the same pattern is extended. Positive
numbers show that the output current flows from
OUTx1 to OUTx2, and negative numbers show
opposite direction.

FUNCTIONAL DESCRIPTION (continued)
Reverse voltage is generated by circulating the current
through the high-side switch.
PWM Current Control
Figure 5 shows bridge current flow and PWM timing
control. Each bridge has its own independent PWM
current controller. The bridge current flows from its
negative pole to ground through a sense pin and a
sense resistor. The sense pin voltage (VSENSEA or
The reference voltage (VREF) must be chosen based on
the load peak current and the sense resistance:
VREF = RSENSEx × ILOAD, PEAK
(1)
V
SENSEB) is proportional to the phase current and
The RSENSEx must be small enough to avoid excessive
power loss in the resistor and prevent large negative
voltage peaks on the SENSEx pin caused by current
recirculation. A few resistances can be paralleled to
achieve the required power rating and resistance value.
Note that if the selected RSENSEx is too small, the
accuracy and performance of the device will be
degraded due to the low measurement sensitivity and
influence of the noise and comparator offsets.
compared to the reference that is set based on the
sequencer value and VREF (Table 2). As soon as VSENSEx
exceeds the VREFx value, a comparator triggers the
off-time and the decay sequence.
In off-time, the current first decays with a slow rate and
then with a fast rate. In the slow decay portion, both
low-side switches of the full-bridge are turned on, and
output voltage is near zero. When 5/8 of the tOFF_SLOW
has expired, the polarity of the output voltage is
reversed by current recirculating to start the fast decay.

FUNCTIONAL DESCRIPTION (continued)
Setting PWM Off-Time
Over-Current Protection (OCP)
The total off-time (slow decay + fast decay) of the PWM
is programmed by an external resistor (ROFF) between
the TOFF pin and ground, as shown in Figure 6. For
stable regulation, a small series RC branch must be
placed parallel to the ROFF (see Table 4).
If the current through any FET exceeds the preset
over-current threshold, all FETs in the H-bridge will be
disabled for a period of approximately 16ms, and the
EN/nFAULT pin will be pulled low. After the period, the
chip resumes operation and EN/nFAULT pin is released.
Over-current conditions are sensed in both directions:
that is, a short to ground, supply, or across the motor
winding will all result in an over-current shutdown.
The relationship between the off-time and the external
resistor value is shown in Off-Time vs. ROFF curve. The
value typically ranges from 10μs to 120μs.
Note that over-current protection does not use the
current sensing circuitry used for PWM current control
and is independent of the ISENSE resistor value or VREF
voltage.

Thermal Shutdown
If the die temperature (TJ) exceeds the maximum safe
temperature threshold, a thermal shutdown event
occurs. With a thermal shutdown the EN/nFAULT pin is
pulled low by the internal open-drain MOSFET that
disables the power stage as shown in Figure 7.

The EN/nFAULT is released when TJ returns back to
the safe range (TJ < TTSD - THYS).
