Microchip Technology MCP19035 Power Module 8A Evaluation Board converts the input voltage rail (typically 12V) to 5V regulated output voltage. This step-down voltage converter has a maximum 8A output current. The board demonstrates the capabilities of the MCP19035 600kHz Synchronous Buck Converter Controller in a typical step-down application. The reference design can be modified to support output voltages from 3.3V to 5V by changing a single resistor.
Microchip Technology AC320208 ATSAME54 Motor Control MCU Card is for the ATSAMxxxBDLCxxx-STK Motor control starter kit. The hardware has the SMART ARM-based MCU, ATSAME54, with integrated onboard debug support. The MCU card can be used with the ATSAMD21BLDC24V-STK low voltage BLDC PMSM motor control starter kit.
Qorvo QPL9057 Flat Gain Amplifiers are designed to provide a flat 2.4dB gain over a wide bandwidth from 1.5GHz to 3.8GHz. These gain amplifiers provide 22.8dB gain, +32dBm OIP3 at a 50mA bias setting, and 0.54dB noise figure. The QPL9057 gain amplifiers require five external components to operate from a single positive supply as they are internally matched using a high-performance E-pHEMT process. The single positive supply includes an RF choke, blocking/bypass capacitors, and a bias resistor going to pin 1.
Microchip Technology MCP8025A Three-phase Brushless DC (BLDC) Motor Gate Drivers with key-off sleep mode are power modules designed for motor current monitoring. These gate drivers integrate various features including key-off sleep mode, a LIN transceiver, a buck voltage regulator, an over-temperature sensor, and an operational amplifier. The MCP8025A gate drivers consist of phase comparator and multiplexer that allow for hardware communication detection. The neutral simulator helps in communication detection without a neutral tap in the motor.
Analog Devices Inc. LT1997 Wide Voltage Gain Selectable Amplifier is a one-chip solution for accurately amplifying voltages. The LT1997 combines a precision operational amplifier with highly-matched resistors. Gains from –13 to +14 with an accuracy of 0.006% (60ppm) can be achieved using no external components. The LT1997 is ideal for use as a difference amplifier, where the excellent resistor matching results in a common mode rejection ratio of greater than 91dB.
