UC3637DW Description

Short technical summary and product information.

The UC3637DW from Texas Instruments is a versatile pulse width modulator circuit designed for PWM motor drive and amplifier applications. It supports both uni-directional and bi-directional drive circuits, offering increased efficiency and reduced component costs compared to conventional drivers.

 

This monolithic device integrates a sawtooth oscillator, an error amplifier, and two PWM comparators with ±100mA output stages. Key protection features include under-voltage lockout, pulse-by-pulse current limiting, and a shutdown port with a temperature-compensated 2.5V threshold. The UC3637DW is characterized for operation from 0°C to 70°C and is available in a 20-SOIC Surface Mount package.

 

Its design flexibility is enhanced by uncommitted PWM comparators, making it suitable for a variety of general-purpose motor control tasks. The device supports single or dual supply operation within a ±2.5V to ±20V input supply range.
