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 V_REF 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.
