The UC3637DW is a Switched Mode Controller for DC motor drive. The pulse width modulator circuit intended to be used for a variety of PWM motor drive and amplifier applications requiring either unidirectional or bi-directional drive circuits. When used to replace conventional drivers, this circuit can increase efficiency and reduce component costs for many applications. All necessary circuitry is included to generate an analogue error signal and modulate two bi-directional pulse train outputs in proportion to the error signal magnitude and polarity. This monolithic device contains a saw tooth oscillator, error amplifier and two PWM comparators with ±100mA output stages as standard features. Protection circuitry includes under-voltage lockout, pulse-by-pulse current limiting and a shutdown port with a 2.5V temperature compensated threshold.
● Pulse-by-pulse current limiting
● Under-voltage lockout
● Uncommitted PWM comparators for design flexibility
● ±5% Initial oscillator accuracy, ±10% over-temperature
● 100mA Source/sink dual output drivers
● Green product and no Sb/Br
