Specifications

5.11.2 Power Supply Sequencing

This section describes the power-up sequence required to ensure proper device operation. The power

supply names described in this section comprise a superset of a family of compatible devices. Some

members of this family will not include a subset of these power supplies and their associated device

modules.

NOTE

All timing requirements and switching characteristics in Section 5.11.3 should be strictly

followed unless otherwise specified.

5.11.2.1 Power Supply Slew Rate Requirement

To maintain the safe operating range of the internal ESD protection devices, TI recommends limiting the

maximum slew rate of supplies to be less than 1.0E + 5 V/s. For instance, as shown in Figure 5-2, TI

recommends having the supply ramp slew for a 1.8-V supply of more than 18 μs.

Figure 5-2 describes the Power Supply Slew Rate Requirement of the device.

5.11.2.2 Power-Up Sequencing

Figure 5-3 describes the Power-Up Sequencing using On Chip Power-on-reset (POR) of the device.
