8.2.2 Slew-Rate Limit for Input Protection

In control systems for motors, abrupt changes in voltages or currents can cause mechanical damages. By controlling the slew rate of the command voltages into the drive circuits, the load voltages ramps up and down at a safe rate. For symmetrical slew-rate applications (positive slew rate equals negative slew rate), one additional op amp provides slew-rate control for a given analog gain stage. The unique input protection and high output current and slew rate of the TLVx197-Q1 make these devices an optimal amplifier to achieve slew-rate control for both dual- and single-supply systems.Figure 43 shows the TLVx197-Q1 in a slew-rate limit design.
