20 Programmable Undervoltage Lockout (UVLO)

The TPS84210 implements internal UVLO circuitry on the VIN pin. The device is disabled when the VIN pin voltage falls below the internal VIN UVLO threshold. The internal VIN UVLO rising threshold is 3.135 V (max) with a typical hysteresis of 300 mV.

If an application requires a higher UVLO threshold on the VIN pin, the UVLO pin can be configured as shown in Figure 33. Table 8 lists standard values for RUVLO to adjust the VIN UVLO voltage up.
