ZXBM5408Q
BRUSHED DC MOTOR DRIVER WITH SERVO CONTROL
Description
Pin Assignments
The DIODESTM ZXBM5408Q is a protected H-Bridge driver designed
specifically for automotive manual headlight beam control and
industrial servo control applications with DC-brush motor loads. The
integrated full-bridge driver output stage is composed of high-current,
low-RDS(on) H-bridge MOSFETs to maximize efficiency.

To simplify the circuit design and minimize external components, the
device integrates voltage and temperature compensated internal
references, amplifiers, and output H-bridge power switches with low

For system flexibility, the servo control forward and reverse
hysteresis, deadband, and angle amplification are easily
programmable by external resistors.

To help protect the motor coil, the ZXBM5408Q provides fault
condition protection, such as RANGE input short to GND, short-to-
supply voltage, or broken wires, by stopping the motor and
disconnecting the output stage. In case of supply undervoltage and
overvoltage, the device shuts down the output drive to help prevent
overvoltage stress on the coil. The overcurrent protection monitors
the output current and shuts down the outputs stage with periodic
retry to help protect the coil from device burnout. Overtemperature
shutdown provides thermal protection for the device.
