Refrigerator Damper and Fan Motor Control Solutions

Refrigerators often use dampers to control airflow and fans to provide air circulation. Discrete solutions have been used for years, but this TI design uses an integrated motor driver to provide easy control, high performance and complete protection. The DRV8848 drives the stepper motor damper, while the DRV10983 drives the BLDC fan with quiet 180° commutation. The BLDC even has closed-loop speed control when using the MSP430G2553 and the DRV8812 for PWM-based power supplies. The entire solution uses a single layer PCB. BLDC and stepper control example code is included in the MCU firmware. Overcurrent, overtemperature and undervoltage protection mechanisms are integrated in the DRV device.

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.

Single-ended input to differential output conversion circuit reference design

This TI Precision Verified Design provides the principles, component selection, simulation, PCB design and measurement details for a single-ended input of a specific differential output circuit that converts a single-ended input from +0.1V to +2.4V ±2.3V differential output on a single +2.7V supply. The output range is specifically limited to maximize its linearity. This circuit consists of 2 amplifiers. An amplifier acts as a buffer, creating the voltage Vout+. The second amplifier inverts the input and increases the reference voltage to produce Vout-. Both Vout+ and Vout- range from 0.1V to 2.4V. The voltage difference Vdiff is the difference between Vout+ and Vout-. This will give a differential output voltage range of +2.3V.
