Product Summary
The UC1620SP/883 is a brushless DC motor driver capable of decoding and driving all 3 windings of a 3-phase brushless DC motor. In addition, an on-board current comparator, oscillator, and high gain Op-Amp provide all necessary circuitry for implementing a high performance, chopped mode servo amplifier. Full protection, including thermal shutdown, pulse-by-pulse current limiting, and under-voltage lockout aid in the simple implementation of reliable designs. Both conducted and radiated EMI have been greatly reduced by limiting the output dv/dt to 150V/ms for any load condition. The UC1620SP/883 is characterized for operation over the full military temperature range of -55°C to +125°C, while the UC1620SP/883 is characterized for 0°C to +70°C.
