36V, 32A power stage for BLDC motors with cycle-by-cycle stall current limiter

This reference design is a power stage for brushless motors in battery-powered garden tools and power tools rated up to 1 kW, powered by a 10-cell lithium-ion battery with a voltage range of 36 to 42 V. This design uses 60V N-channel NexFET(TM) with ultra-low drain-to-source resistance (RDS_ON) of 1.8 mΩ in a SON5x6 SMD package, resulting in a small 57 × 59 mm PCB footprint. This design uses a three-phase gate driver to drive the three-phase MOSFET bridge, which can operate from 6V to 60V and supports programmable gate current with a maximum setting of 2.3A sink/1.7A source. The C2000™ Piccolo™ LaunchPad™ LAUNCHXL-F28027 is used with this power stage and implements 120-degree trapezoidal control of BLDC motors via Hall sensors in software. The gate driver's cycle-by-cycle current limiting feature limits the maximum current allowed in this power stage to a safe level, thereby protecting the board from overcurrent issues caused during motor shutdown.

Precision Output Current Limit Circuit Reference Design for TPS61088 Boost Converter

This reference design delivers an accurate output current limit solution for the TPS61088 boost converter. This feature is realized by an output current sense resistor and a low cost operational amplifier. When the output current is higher than the current limit point, the output of the operational amplifier will be higher than the TPS61088’s 1.204V reference voltage. So the output voltage drops. If the output current continuously increases, the output voltage will be further decreased. Thus the maximum output power will always be limited below a certain level.
