Overview
The UC1637 is a pulse width modulator (PWM) circuit designed for DC motor drive and amplifier applications, offering single or dual supply operation with a wide input supply range of +2.5V to +20V.
Key Features
The device features a sawtooth oscillator, error amplifier, and two PWM comparators with 100mA output stages. It also includes protection circuitry such as under-voltage lockout, pulse-by-pulse current limiting, and shutdown input with a temperature-compensated 2.5V threshold.
Applications
The UC1637 is suitable for a variety of PWM motor drive and amplifier applications, including uni-directional or bi-directional drive circuits, and can increase efficiency and reduce component costs in many applications.
