CSD88584Q5DC
40-V, N channel synchronous buck NexFET™ power MOSFET, SON 5 mm x 6 mm Dual-Cool™ power block, 50 A
Data sheet
CSD88584Q5DC
- Half-bridge power block
- High-density SON 5mm × 6mm footprint
- Low RDS(ON) for minimized conduction losses
- 2.4W PLoss at 35A
- DualCool™ thermally enhanced package
- Ultra-low-inductance package
- RoHS compliant
- Halogen free
- Lead-free terminal plating
The CSD88584Q5DC 40V power block is an optimized design for high-current motor control applications, such as handheld, cordless garden and power tools. This device utilizes TI’s patented stacked die technology in order to minimize parasitic inductances while offering a complete half bridge in a space saving thermally enhanced DualCool™ 5mm × 6mm package. With an exposed metal top, this power block device allows for simple heat sink application to draw heat out through the top of the package and away from the PCB, for superior thermal performance at the higher currents demanded by many motor control applications.
