Full-Bridge 600V/3.5A Power Driver Features SiP Format

STMicroelectronics’ has released its PWD5F60 high-density power driver, the second in a new series of power-driver systems-in-package addressing high-voltage brushed DC and single-phase brushless motor applications. It integrates a 600V/3.5A single-phase MOSFET bridge with gate drivers, bootstrap diodes, protection features, and two comparators in a 15 mm x 7 mm outline. The thermally efficient system-in-package occupies 60% less board real-estate than discrete components, while boosting reliability and simplifying design and assembly.

As a single-phase full-bridge module, the PWD5F60 is tailored for driving brushed DC motors in applications such as industrial pumps and fans, blowers, domestic appliances, and factory-automation systems. It is particularly targeted at the appliances using single-phase brushless motors that guarantee high durability and efficiency at a reasonable cost. It is also cost-effective and convenient for use in power supply units.

With on-resistance of 1.3 8Ω, the PWD5F60’s integrated N-channel MOSFETs ensure high efficiency for handling medium-power loads. The gate drivers are optimized for reliable switching and low EMI (electromagnetic interference), while the integrated bootstrap diodes enable high-voltage startup with no need for external diodes and passive components to supply the high-side inputs.

Flexibility is assured by two embedded uncommitted comparators that allow an easy implementation of peak current control or over-current and over-temperature protection features. The peak-current control used in conjunction with positioning Hall-effect sensors allows to achieve a stand-alone controller with no need of a dedicated MCU and hence drastically reducing the cost of control electronics. Further flexible features include adjustable dead-time and the option to configure the MOSFETs as a single full bridge or two half bridges. Operating voltage range extends from 10 V to 20 V and inputs are compatible with 3.3 V-15 V control signals to ease interfacing with Hall sensors or a host microcontroller or DSP

Cross-conduction prevention and under-voltage lockout are already built-in to protect the device by preventing operation in low-efficiency or dangerous conditions. The PWD5F60 is in production and available now, packaged as a multi-island VFQFPN device, from $2.15 for orders of 1,000 pieces.
