The ZXBM5409Q 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-RDSON 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 RDSON.
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 ZXBM5409Q provides fault condition protection, such as reference 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.
The ZXBM5409Q is available in industry standard PDIP-8 package and is qualified to AEC-Q100 Grade 1 and is automotive compliant supporting PPAPs.
