38 / 128 page ![]() i.MX RT1170 Crossover Processors Data Sheet for Consumer Products, Rev. 1, 05/2021 38 NXP Semiconductors Electrical characteristics 4.2.2 Internal POR and power detect Internal detector monitors VDD_SOC_IN and VDD_LPSR_DIG. Internal POR will be asserted whenever VDD_SOC_IN or VDD_LPSR_DIG are lower than the valid voltage values shown in the Table 16. 4.2.3 Integrated LDO voltage regulator parameters Various internal supplies can be powered ON from internal LDO voltage regulators. The on-chip LDOs are intended for internal use only and should not be used to power any external circuitry. See the i.MX RT1170 Reference Manual (IMXRT1170RM) for details on the power tree scheme. 4.2.3.1 LDO_SNVS_ANA Table 17 shows the parameters of LDO_SNVS_ANA. 4.2.3.2 LDO_SNVS_DIG Table 18 shows the parameters of LDO_SNVS_DIG. Table 16. Internal POR and power detect Symbol Description Value Unit Vdetlpsr1p0_H 1.0 V supply valid 0.75 V Vdetsoc1p0_H 1.0 V supply valid 0.75 V Hystdet1p0 The detector hysteresis 100 mV Table 17.
