8.3.2.2 Immunity to SENSE Pin Voltage Transients

The TLV841S is immune to short voltage transient spikes or excursion on the SENSE pin. To further improve the noise immunity on the SENSE pin, placing a 10 nF to 100 nF capacitor between the SENSE pin and GND can reduce the sensitivity to sensitivity to transient voltages on the monitored signal.

Sensitivity to transients depends on both transient duration and overdrive (amplitude) on the transient voltage. Overdrive is defined by how much VSENSE exceeds the specified threshold and is important to know because the smaller the overdrive, the slower the resonse of the output. Threshold overdrive is calculated as a percent of the threshold in question, as shown in Equation 2.

Equation 2. Overdrive = | ((VSENSE / VIT-) – 1) × 100% |
