The UC1637 is a pulse width modulator circuit intended to be used for a variety of
PWM motor drive and amplifier applications requiring either uni-directional 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 analog error signal and modulate
two bi-directional pulse train outputs in proportion to the error signal magnitude
and polarity.
This monolithic device contains a sawtooth 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.
The UC1637 is characterized for operation over the full military temperature range
of -55°C to +125°C, while the UC2637 and UC3637 are characterized for -25°C to
+85°C and 0°C to +70°C, respectively.
