Among the many automotive applications that the VNH9030AQ integrated full-bridge DC motor driver can handle are functional-safety applications. The driver incorporates sophisticated diagnostics and features a dedicated pin for real-time output status, which reduces the need for external circuitry and lowers the bill of materials.
The VNH9030AQ effectively manages mid- and low-power DC motor-driven applications, including door-control modules, washer pumps, powered lift gates, powered trunks, and seat adjusters, with an RDS(on) of 30m? per leg.
Integrated non-dissipative current-sense circuitry monitors the current passing through the device to identify each motor phase, enhancing the driver’s high overall efficiency and preserving external components. Utilizing zonal controller platforms is made easier by the extremely low standby power consumption across the whole working temperature range.
The VNH9030AQ Integrates:
- The high-side and low-side MOSFETs with gate drivers, diagnostics, and protection against overvoltage transients, undervoltage, short-circuit conditions, and cross conduction.
- Flexibility to configure the MOSFETs either in parallel or in series allows use in systems involving multiple motors or to meet other specific requirements.
The new driver is part of a family of devices that leverage ST’s latest VIPower M09 technology, which permits efficient, monolithic integration of power and logic circuitry. All products feature an innovative 6mm x 6mm thermally enhanced triple-pad QFN package designed for optimal underside cooling and share a common pinout to ease layout and software reuse.
