1 / 8 page DESCRIPTION The UC3620 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/ µs for any load condition. The UC1620SP is characterized for operation over the full military tem- perature range of -55 °C to +125°C, while the UC3620SP is charac- terized for 0 °C to +70°C. FEATURES • 2A Continuous, 3A Peak Output Current • 8V to 40V Operation • Internal High Gain Amplifier for Velocity Control Applications • TTL Compatible Hall Inputs • Mask Programmable Decode Logic • Pulse-by-Pulse Current Limiting • Internal Thermal Shutdown Protection • Under-Voltage Lockout • Available in SP Hermetic Package BLOCK DIAGRAM Switchmode Driver for 3- ∅ Brushless DC Motors UC1620 UC3620 3/97 1 |
