Low Quiescent Current Programmable Delay Supervisory Circuit
The TPS3808G01-Q1 microprocessor supervisory circuits monitor system voltages from 0.4 V to 5 V, asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the useradjustable delay time after the SENSE voltage and MR return above their thresholds. Datasheet is available in Texas Instruments website.
The TPS3808G01-Q1 device uses a precision reference to achieve 0.5% threshold accuracy for VIT ≤ 3.3 V. The reset delay time can be set to 20 ms by disconnecting the CT pin, 300 ms by connecting the CT pin to VDD using a resistor, or can be useradjusted from 1.25 ms to 10 s by connecting the CT pin to an external capacitor. The TPS3808G01-Q1 has a very low typical quiescent current of 2.4 μA, so it is well suited for battery-powered applications.
Low Dropout Linear Regulator
The TPS74801-Q1 low-dropout (LDO) provides an easy-to-use robust power management solution for a wide variety of applications. User programmable soft-start minimizes stress on the input power source by reducing capacitive inrush current on start-up. The soft-start is monotonic and well- suited for powering many different types of Monitoring or Provides a Sequencing Signal processors and ASICs. The enable input and power for Other Supplies good output allow easy sequencing with external regulators. This complete flexibility permits the user to configure a solution that meets the sequencing Voltage Startup requirements of FPGAs, DSPs, and other applications with special start-up requirements.
A precision reference and error amplifier deliver 2% accuracy over load, line, temperature, and process. The device is stable with any type of capacitor greater than or equal to 2.2 μF, and is fully specified SON-10 and 5 x 5 QFN-20 Packages from –40°C to 105°C for the DRC package, and from –40°C to 125°C for the RGW package.

Power Sequency
The PS and PL power supplies are fully independent. PS power supplies (VCCPINT, VCCPAUX, VCCPLL, VCCO_DDR, VCCO_MIO0, and VCCO_MIO1) can be powered before or after any PL power supplies. The PS and PL power regions are isolated to prevent damage. The recommended power-on sequence is VCCPINT, then VCCPAUX and VCCPLL together, then the PS VCCO supplies (VCCO_MIO0, VCCO_MIO1, and VCCO_DDR) to achieve minimum current draw and ensure that the I/Os are 3-stated at power-on. The PS_POR_B input is required to be asserted to GND during the power-on sequence until VCCPINT, VCCPAUX and VCCO_MIO0 have reached minimum operating levels to ensure PS eFUSE integrity.
