UC2637J - DC Motor Controller

Download the UC2637J datasheet PDF. This datasheet also covers the UC2637 variant, as both devices belong to the same dc motor controller family and are provided as variant models within a single manufacturer datasheet.

General Description

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 bidirectional drive circuits.

Key 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.
  • Uncommitted PWM Comparators for Design Flexibility.
  • Dual 100mA, Source/Sink Output Drivers BLOCK.
