ZXBM5210
REVERSIBLE DC MOTOR DRIVE WITH SPEED CONTROL
Description
Pin Assignments
The ZXBM5210 is a single chip solution for driving a single-coil
reversible direct current (DC) fans and motors. The integrated fullbridge driver output stage is designed to minimize audible switching
noise and electromagnetic interference (EMI) providing a low noise
NEW PRODUCT
solution
For system flexibility, the device has four modes of operation:
Forward, Reverse, Brake and Standby selected via FWD and REV
pins. The Forward and Reverse modes provide the motor rotation
direction control, the Brake mode allows quick stop and the Standby
SO-8
mode helps system efficiency by powering down most of the internal
circuits to consume less than 32uA typical. The motor speed can be
adjusted by changing the duty ratio of the PWM signal on the FWD or
REV pins in the PWM mode or alternatively by adjusting DC voltage
input signal to the VREF pin in the VREF speed control mode.
To help protect the IC and the motor coil the ZXBM5210 includes
under voltage, over voltage, over current and over temperature
protections. Once the safe operating range has been exceeded the
device shuts down the output drive to help prevent over stress on the
SO-8EP
IC or the coil. The device internal current protection threshold is 1.5A
typical.
The ZXBM5210 is available in the standard SO8 and thermally
enhanced SO8-EP packages.

Brake mode – Short circuit brake with low side switches on
In the brake mode, switches S2 and S4 are ON allowing the motor to stop quickly. All the internal control circuits are fully operational.
In the standby mode all the output drive switches are off and additionally, the internal circuits are also turned off to minimize power consumption.
The power consumption in the standby mode is less than in the brake mode. If running motor enters the Standby mode, due to the body diodes
the motor free wheels to idle state. Whenever the motor enters the standby mode from any mode (except the brake mode) the control logic will
remain active in previous mode for at least 125µs before shutting down the internal circuits. To prevent device entering the standby mode during
operating mode changes, the mode change signals should be completed within 125µs.
In the forward mode, with switches S1-S2 ON and S3-S4 OFF, OUT1 is high and OUT2 is low. The motor current flows from OUT1 to OUT2. In
the reverse mode, switches S1-S4 are ON while S1-S2 are OFF to allow motor current flow from OUT2 to OUT1.
In the forward or reverse mode, for VREF speed control, the output drive duty ratio is generated internally based on the voltage on the VREF pin.
For PWM speed control, external PWM signals applied to the FWD or REV pins control the PWM switching of the low side S2 (forward mode)
or S4 (reverse mode). See application section for further details.
The ZXBM5210 has three modes of speed control: VREF speed control mode, PWM speed control mode and by adjusting the supply voltage

Application Note (cont.)
Motor Speed Control with DC Voltage on VREF Pin
Motor speed can be controlled by adjusting the DC voltage into the VREF pin. The output drive PWM duty ratio is defined by the ratio of the VREF
voltage to the supply VDD voltage.
In VREF speed control mode, FWD and REV pins are only used for direction control and therefore high frequency PWM control signal should not
be applied to the FWD and REV pins. If repetitive direction changes required, it is recommended to keep direction change frequency of below

Motor Speed Control with a PWM Input Signal
Motor speed can be controlled by adjusting the duty cycle of the PWM speed control signal into the FWD or REV while keeping the VDD pin at
the nominal motor voltage. In this mode the input voltage on the VREF pin must be greater than or equal to VDD.
In PWM speed control mode the high side switches S1 and S3 are kept fixed while the low side switches S2 or S4 are switched. In the forward
mode, S1 is kept switched on, S2 is switched in accordance with the PWM signal and S3 and S4 are switched off. In reverse mode, S3 is
switched on, S4 is switched in accordance with the PWM signal and S1 and S2 are switched off.

The motor speed is proportional to the input PWM signal duty. For example, for a 12V motor the VDD pin is maintained at 12V while varying the
PWM control signal duty to adjust the motor speed linearly. The timing diagram below shows the output O1 and O2 in relation to PWM speed
control signal at PWM pin.
Frequency of PWM speed control signal can be between 8kHz to 100kHz. Recommended typical PWM signal frequency is 25kHz to keep
switching frequency away from the audible band.

Application Note (cont.)
Motor Speed Control with a PWM Input Signal (cont.)
Depending on the motor design and its inertia the minimum start-up PWM duty required can be typically between 30% - 50%. While the motor is
rotating minimum PWM duty can generally be reduced down to 20%. How small the PWM duty can be without stalling the motor depends on the
motor mechanical and coil design parameters and not limited by the output capability of the device. If voltage at VDD is lower than the nominal
motor voltage, both start-up PWM duty and minimum running PWM duty required will be higher.
NEW PRODUCT
Motor Speed Control by DC Supply Voltage
Motor speed can be controlled by varying the VDD supply voltage while the FWD and REV pins are set to either a logic high or low depending on
forward or reverse direction needed. The VREF must be equal to VDD in this mode. For example, if the VDD for a 12V motor is changed from
12V to 3V the speed will be reduced from 100% to 25%.
Re-Circulating Capacitor
During motor operation when the low side switch is turned off the bridge or the motor voltage may overshoot to high levels if there is no current
path for the energy in the motor to flow. Such high voltages can damage the IC. A current path can be provided by adding a bypass capacitor
from the VDD or VM to the GND. The value of the bypass capacitor depends on the motor coil design, motor current, motor voltage and the
IC voltage limits. This could be in the range of 0.47µF for low current applications to 10uF or more for large current applications.
Dead-Time
During motor current reversal (for motor rotation direction reversal), switch position changes between S1-S2 and S3-S4. Such change may result
in cross conduction between high side and low side MOSFETS, e.g. S1 and S4 or S2 and S3. To prevent cross conduction the IC provides a
dead time 3µs typical during current reversal or fast turn on of the low side MOSFETs.
Back-Rush Voltage
Depending on motor characteristics, the environment and the ambient conditions back-rush voltage (at the bridge) may fluctuate during brush
commutation and PWM switching. Due to the energy in the coil this back-rush voltage can reach high levels if no adequate alternative current
path is provided when inductor current path is interrupted. The back-rush voltage overshoot should not be allowed to go beyond the operating
voltage range of the IC. This backrush voltage overshoot can be minimized by using a re-circulating bypass capacitor at the VDD and VM pins.
The value of the re-circulating bypass capacitor depends on the motor coil design, motor current, motor voltage and the IC voltage limits. This
could be 0.47µF for low current applications to 10uF or more for large current applications.
Under Voltage Lockout
To make sure the minimum voltage needed to operate the driver is supplied, the driver has an under voltage lock out. At start up the device will
only start if the supply voltage is typically 2.8 or greater. During normal operation, the device will switch off all the output switches and power
down if the supply voltage drops below 2.6V typical.
Over Voltage Protection
When the supply voltage exceeds 20.7V (typical) the driver will turn-off all the output switches. The driver will return to normal condition if the
supply voltage drops below 19V (typical) provided no other fault condition or signals are preventing it to enter normal operation.
In-Rush Current
It is recommended to use the PWM duty cycle to control the average voltage supplied to the motor during power up, standby mode, brake mode
or during motor direction reversal. If a PWM signal is not available it is recommended to use a current limiting resistor or other protection
devices if needed.
Over-Current Setting and Protection
The internal over current protection (OCP) threshold is 1.5A typical at 12V supply +25°C.
When the motor current exceeds the OCP threshold for longer than 10µs typical on any of the H-Bridge switches, the device will switch of all the
output switches and remain off for 5ms typical. The IC returns to normal operation after the 5ms if over current condition has gone away. If the
motor current is still higher than the OCP threshold, the device will enter another 5ms standby mode.
Thermal Shutdown
The device has an internal thermal shutdown to prevent a thermal run-away scenario. The thermal shutdown is triggered when the junction
temperature of the device reaches +165°C. It will remain in standby mode until the junction temperature falls by +25°C.
Reverse Voltage Protection
If reverse protection is needed this can be achieved by adding an external diode to the VDD and VM pins.
