DESCRIPTION/ORDERING INFORMATION
The DRV8823 provides an integrated motor driver solution for printers and other office automation equipment
applications.
The motor driver circuit includes four H-bridge drivers. Each of the motor driver blocks employ N-channel power
MOSFETs configured as an H-bridge to drive the motor windings.
A simple serial interface allows control of all functions of the motor driver with only a few digital signals. A
low-power sleep function is also provided.
The motor drivers provide PWM current control capability. The current is programmable, based on an externally
supplied reference voltage and an external current sense resistor. In addition, eight current levels (set via the
serial interface) allow microstepping with bipolar stepper motors.
Internal shutdown functions are provided for over current protection, short circuit protection, under voltage
lockout and overtemperature.
The DRV8823 is packaged in a 48 pin HTSSOP package (Eco-friendly : RoHS & no Sb/Br).

Bridge Control
The xENBL bits in the serial interface registers enable current flow in each H-bridge when set to "1".
The xPHASE bits in the serial interface registers control the direction of current flow through each H-bridge. The
following table shows the logic:

xOUT2

Current Regulation
The motor driver employs fixed-frequency PWM current regulation (also called "current chopping"). When a
winding is activated, the current through it rises until it reaches a threshold, then the current is switched off until
the next PWM period.
The PWM frequency is fixed at 50 kHz. It may also be set to 100 kHz via factory option.
The PWM chopping current is set by a comparator which compares the voltage across a current sense resistor
connected to the xISEN pins, multiplied by a factor of 5, with a reference voltage. The reference voltage is input
from the VREF pin.
The full-scale (100%) chopping current is calculated as follows:
5
(1)
Example:
If a 0.5-Ω sense resistor is used and the VREFx pin is 2.5 V, the full-scale (100%) chopping current is
2.5 V/(5 * 0.5 Ω) = 1 A.
Three serial interface register bits per H-bridge (xI2, xI1 and xI0) are used to scale the current in each bridge as
a percentage of the full-scale current set by the VREF input pin and sense resistance. The function of the bits is
shown below:

Blanking Time
After the current is enabled in an H-bridge, the voltage on the xISEN pin is ignored for a fixed period of time
before enabling the current sense circuitry. This blanking time is fixed at 3.75 ms. Note that the blanking time also
sets the minimum on time of the PWM.

Decay Mode
During PWM current chopping, the H-bridge is enabled to drive through the motor winding until the PWM current
chopping threshold is reached. This is shown in Figure 3 as case 1. The current flow direction shown indicates
positive current flow in the step table below.
Once the chopping current threshold is reached, the H-bridge can operate in two different states, fast decay or
slow decay.
In fast decay mode, once the PWM chopping current level has been reached, the H-bridge reverses state to
allow winding current to flow in a reverse direction. As the winding current approaches zero, the bridge is
disabled to prevent any reverse current flow. Fast-decay mode is shown in Figure 3 as case 2.
In slow-decay mode, winding current is re-circulated by enabling both of the low-side FETs in the bridge. This is
shown in Figure 3 as case 3.

Figure 3. Decay Mode
The DRV8823 supports slow decay and also a mixed decay mode. Mixed decay mode begins as fast decay, but
at a fixed period of time (75% of the PWM cycle) switches to slow decay mode for the remainder of the fixed
PWM period.
Slow or mixed decay mode is selected by the state of the xDECAY bits in the serial interface registers. If the
xDECAY bit is 0, slow decay is selected. If the xDECAY bit is 1, mixed decay is selected.

Protection Circuits
The DRV8823 is fully protected against undervoltage, overcurrent and overtemperature events.
Overcurrent Protection (OCP)
All of the drivers in DRV8823 are protected with an OCP (Over-Current Protection) circuit.
The OCP circuit includes an analog current limit circuit, which acts by removing the gate drive form each output
FET if the current through it exceeds a preset level. This circuit will limit the current to a level that is safe to
prevent damage to the FET.
A digital circuit monitors the analog current limit circuits. If any analog current limit condition exists for longer than
a preset period, all drivers in the device will be disabled.
The device is re-enabled upon the removal and re-application of power at the VM pins.
Thermal Shutdown (TSD)
If the die temperature exceeds safe limits, all drivers in the device will be shut down.
The device will remain disabled until the die temperature has fallen to a safe level. After the temperature has
fallen, the device may be re-enabled upon the removal and re-application of power at the VM pin.
Undervoltage Lockout (UVLO)
If at any time the voltage on the VM pins falls below the undervoltage lockout threshold voltage, all circuitry in the
device will be disabled. Operation will resume when VM rises above the UVLO threshold. The indexer logic will
be reset to its initial condition in the event of an undervoltage lockout.
Shoot-Through Current Prevention
The gate drive to each FET in the H-bridge is controlled to prevent any cross-conduction (shoot through current)
during transitions.
Serial Data Transmission
Data transfers consist of sixteen bits of serial data, shifted into the SDATA pin LSB first.
On serial writes to DRV8823, additional clock edges following the final data bit will continue to shift data bits into
the data register; therefore, the last 16 bits presented will be latched and used.
One of two registers is selected by setting bits in an address field in the four upper bits in the serial data
transferred (ADDR in the tables below). One 16-bit register is used to control motor #1 (bridges A & B), and a
second 16-bit register is used to control motor 2 (bridges C & D).
Data can only be transferred into the serial interface if the SCS input pin is active high.
Data is initially clocked in to a temporary holding register. This data is latched into the motor driver on the rising
edge of the SSTB pin. If the SSTB pin is tied high at all times, the data will be latched in after all 16 bits have
been transferred.

THERMAL INFORMATION
Thermal Protection
The DRV8823 has thermal shutdown (TSD) as described above. If the die temperature exceeds approximately
150°C, the device will be disabled until the temperature drops to a safe level.
Any tendency of the device to enter thermal shutdown is an indication of either excessive power dissipation,
insufficient heatsinking, or too high an ambient temperature.

Power dissipation in the DRV8823 is dominated by the power dissipated in the output FET resistance, or RDS(ON).
Average power dissipation when running a stepper motor can be roughly estimated by Equation 2.
PTOT = 4
·
RDS(ON)
·
(IOUT(RMS))
2
(2)
where PTOT is the total power dissipation, RDS(ON) is the resistance of each FET, and IOUT(RMS) is the RMS output
current being applied to each winding. IOUT(RMS) is equal to the approximately 0.7x the full-scale output current
setting. The factor of 4 comes from the fact that there are two motor windings, and at any instant two FETs are
conducting winding current for each winding (one high-side and one low-side). Remember that the DRV8823 has
two stepper motor drivers, so the power dissipation of each must be added together to determine the total device
power dissipation.
The maximum amount of power that can be dissipated in the DRV8823 is dependent on ambient temperature
and heatsinking. The thermal dissipation ratings table in the datasheet can be used to estimate the temperature
rise for typical PCB constructions.
Note that RDS(ON) increases with temperature, so as the device heats, the power dissipation increases. This must
be taken into consideration when sizing the heatsink.
Heatsinking
The PowerPAD™ package uses an exposed pad to remove heat from the device. For proper operation, this pad
must be thermally connected to copper on the PCB to dissipate heat. On a multi-layer PCB with a ground plane,
this can be accomplished by adding a number of vias to connect the thermal pad to the ground plane. On PCBs
without internal planes, copper area can be added on either side of the PCB to dissipate heat. If the copper area
is on the opposite side of the PCB from the device, thermal vias are used to transfer the heat between top and
bottom layers.
For details about how to design the PCB, refer to TI application report SLMA002, " PowerPAD™ Thermally
Enhanced Package" and TI application brief SLMA004, " PowerPAD™ Made Easy", available at www.ti.com.
In general, the more copper area that can be provided, the more power can be dissipated. Figure 5 shows
thermal resistance vs. copper plane area for both a single-sided PCB with 2-oz copper heatsink area, and a
4-layer PCB with 1-oz copper and a solid ground plane. Both PCBs are 76 mm x 114 mm, and 1.6 mm thick. It
can be seen that the heatsink effectiveness increases rapidly to about 20 cm2, then levels off somewhat for
larger areas.
Six pins on the center of each side of the package are also connected to the device ground. A copper area can
be used on the PCB that connects to the PowerPAD™ as well as to all the ground pins on each side of the
device. This is especially useful for single-layer PCB designs.
