PWD5T60 [STMicroelectronics]

The PWD5T60 is a is a three-phase high-density power driver integrating gate driver and six N-channel power MOSFETs. The PWD5T60 is the optimal solution for motor drive applications such as fans, pumps and small appliances.

The integrated power MOSFETs have RDS(on) of 1.38 Ω and 500 V blocking voltage. The high integration of the device allows to efficiently drive loads with reduced footprint, making PWD5T60 the optimal solution for space constrained applications.

The device has dedicated input pins for each output and a shutdown pin. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing with control devices. Matched delays between low-side and high-side sections guarantee no cycle distortion and allow high-frequency operation.

Robustness is a distinctive factor of PWD5T60. Prevention from cross conduction is ensured by interlocking and deadtime functions and a comparator featuring advanced smart ShutDown function ensures fast and effective protection against overload and overcurrent.

The dedicated UVLO protections on both low-side and high-side prevent the power switches from operating in low efficiency or dangerous conditions, enabling optimal and fail-safe operation.

The zero-drop integrated bootstrap diodes as well as all of the embedded features enable the design of compact and simple PCB layout, and reduce the overall bill of material and application cost. The device is available in a compact VFQFPN 12x12x0.95 mm.
