SG1731

Motor and Fan Controllers - DC MOTOR PULSE WIDTH MODULATOR; ±3.5 V to ±15 V Control Supply\n±2.5 V to ±22 V Driver Supply\n Dual 100 mA Source/Sink Output Drivers \n 5 kHz to 350 kHz Oscillator Range \n High Slew Rate Error Amplifier \n Adjustable Deadband Operation \n Digital SHUTDOWN Input;

The SG1731 is a pulse width modulator circuit designed specifically for DC motor control. It provides a bi-directional pulse train output in response to the magnitude and polarity of an analog error signal input. The device is useful as the control element in motor-driven servo systems for precision positioning and speed control, as well as in audio modulators and amplifiers using carrier frequencies to 350 kHz. The circuit contains a triangle waveform oscillator, a wideband operational amplifier for error voltage generation, a summing/scaling network for level-shifting the triangle waveform, externally programmable PWM comparators and dual ±100 mA, ±22 V totem pole drivers with commutation diodes for full bridge output. A SHUTDOWN terminal forces the drivers into a floating high-impedance state when driven LOW. Supply voltage to the control circuitry and to the output drivers may be from either dual positive and negative supplies, or single-ended.Microchip Ordering Part  Standard Microcircuit Drawing (SMD)SG1731J-DESC Cross Reference 5962-9669901MEASG1731J-DESC Cross Reference 5962-9669901MEX
