Description
Switched Mode Controller for DC Motor Drive UC1637 UC2637 UC3637 .
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-dir.
Features
* Single or Dual Supply Operation
* ±2.5V to ±20V Input Supply Range
* ±5% Initial Oscillator Accuracy; ± 10% Over Temperature
* Pulse-by-Pulse Current Limiting
* Under-Voltage Lockout
* Shutdown Input with
Temperature Compensated 2.5V Threshold
Applications
* requiring either uni-directional or bidirectional 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 p
