ZXBM5210
REVERSIBLE DC MOTOR DRIVE WITH SPEED CONTROL
Description
The ZXBM5210 is a single chip solution for driving a single-coil
reversible direct current (DC) fans and motors. The integrated full-
bridge driver output stage is designed to minimize audible switching
noise and electromagnetic interference (EMI) providing a low noise
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
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
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.

Typical Applications Circuit
ZXBM5210
Note:
4. C1 is for power stabilization and to strengthen the noise immunity, the recommended capacitance is 100nF to 1µF or more.
C2 is a re-circulating capacitor for back rush voltage and recommended capacitance is 100nF for low current applications to 10µF or more for large
current applications. See application note section

Notes:
5. Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings
only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device
reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time
6. The absolute maximum supply voltage of 24V is a transient stress rating and is not meant as a functional operating condition. It is not recommended
to operate the device at the absolute maximum rated conditions for any period of time.
7. SO-8 soldered to minimum recommended landing pads (see Package Outline Dimension section) on a 1”x1” two-layer 2oz.copper FR4 PCB
(1.6mm thickness) without any via or copper flood on the bottom layer. See thermal de-rating curves in the thermal performance section.
8. SO-8EP exposed pad soldered to minimum recommended landing pads (see Package Outline Dimension section) on a 2”x2” two-layer 2oz.copper
FR4 PCB (1.6mm thickness) with four thermal vias in the exposed PAD to the copper flood on the bottom layer. See thermal de-rating curves in the
thermal performance section.
