Abstract
A variable slew control for output circuits is disclosed. The slew control circuit automatically adjusts the rate in which voltage on a slew node is driven to a reference voltage, minimizing noise at the output device driver. The variable slew control decreases the slew rate of the slew node during periods when di/dt is at a high level, but allows the voltage on the slew node to drop at faster rates during times when di/dt at the output driver is low.
