7.3.2 Transient Immunity

The TLV4011-Q1 is immune to short negative transients on the SENSE pin. Sensitivity to transients is dependent on threshold overdrive as shown in Figure 7-2 and Figure 7-3. These graphs show the duration that the transient is below VIT compared to the magnitude of the voltage drop below VIT, called the threshold overdrive voltage. Any combination of transient duration and overdrive voltage which lies above the curves will result in RESET being asserted low. Any transient which lies below the curves will be ignored by the device.
