Part Details for OPA2374 by Texas Instruments

The PMP8824 uses the TPS53318 DCAP Mode 8A step-down converter to power the VCCR_GXB, VCCL_GXB, VCCT_GXB rails in Altera Arria® V FPGAs enabling tight load regulation, low total component count, high efficiency, high power density, and excellent thermal performance. The complete design fits i

This reference design is a power stage for brushless motors in battery-powered garden and power tools rated up to 1 kW: operating from a 10-cell lithium-ion battery with a voltage range from 36 to 42 V. The design uses 60V: N-channel NexFETsTM featuring a very low drain-to-source resistance (RDS_ON ) of 1.8 mΩ in a SON5x6 SMD package: which results in a very small PCB form factor of 57 × 59 mm. The three-phase gate-driver is used to drive a three-phase MOSFET bridge: which can operate from 6 to 60 V and supports programmable gate current with maximum setting of 2.3-A sink / 1.7-A source. The C2000™ Piccolo™ LaunchPad™ LAUNCHXL-F28027 is used along with this power stage and 120 degree trapezoidal control of BLDC motor with Hall sensors is implemented in software. The cycle by cycle current limit feature in the gate-driver protects the board from excessive current that is caused during motor stalls: by limiting the maximum current allowed in the power stage to a safe level.

The Three-Phase Brushless DC Motor Driver reference design is a 10A: 3-phase brushless DC drive stage based on the DRV8301 pre-driver and CSD18533Q5A NextFET™ power MOSFET. It has three low side current sense amps (two internal to DRV8301: one external). The design also leverages a 1.5A step down buck converter: is fully protected with short circuit: thermal: and shoot-through protection: and is easily configured via a SPI interface. It is ideal for sensorless: brushless control techniques and drive stage design.
