8.3.1 Voltage Monitoring

Each SENSEm (m = 1, 2, 3, 4L) pin can be set to monitor any voltage threshold above 0.4 V using an external resistor divider. The SENSE4H pin can be used for any overvoltage detection greater than 0.4 V, or for negative voltage detection using an external resistor divider (see the Sensing a Negative Voltage section). A broad range of voltage threshold and reset delay time adjustments can be supported, allowing these devices to be used in a wide array of applications.

The TPS3860x0 is relatively immune to short negative transients on the SENSEn pin. Sensitivity to transients depends on threshold overdrive, as shown in (Figure 14).
