UC3637DWTR Description

Short technical summary and product information.

The UC3637DWTR 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 when replacing conventional drivers.

 

This monolithic device integrates a sawtooth oscillator, 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 input with a 2.5V temperature-compensated threshold. The UC3637DWTR is characterized for operation from 0°C to 70°C.

 

It is housed in a 20-SOIC package and supports surface mount installation. The device operates with a supply voltage range of ±2.5V to ±20V and provides dual 100mA source/sink output drivers. Its function as a controller for commutation and direction management makes it suitable for general-purpose motor control applications.
