The UC1637L from Texas Instruments is a pulse width modulator circuit designed for a variety of PWM motor drive and amplifier applications requiring uni-directional or bi-directional drive circuits. This monolithic device integrates a sawtooth oscillator, an error amplifier, and two PWM comparators with ±100mA output stages.
Key electrical specifications include a supply voltage range of ±2.5V to ±20V, with an absolute maximum rating of 20V. The oscillator accuracy is ±5% initially and ±10% over temperature. The operating temperature range is -55°C to 125°C, making it suitable for demanding environments.
This controller can increase efficiency and reduce component costs when used to replace conventional drivers. It includes circuitry to generate an analog error signal and modulate two bi-directional pulse train outputs proportionally to the error signal's magnitude and polarity. The device is available in CDIP (J) and LCCC (FK) packages.
The UC1637L is intended for applications requiring precise control of DC motor speed and direction. Its design flexibility allows for integration into various motor drive systems.
