2 Device Versions

There are different orderable part numbers (PNs) of the TPS6594-Q1 device available with unique NVM settings to support different end product use cases and processor types. The unique NVM settings for each PMIC device is optimized per PDN design to support different processors, processing loads, SDRAM types, system functional safety levels, and end product features (such as low power modes, processor voltages, and memory subsystems). The NVM settings can be identified by both NVM_ID and NVM_REV registers. Each PMIC device is distinguished by the part number, NVM_ID, and NVM_REV values listed in Table 2-1.

Table 2-1 Dual TPS6594-Q1 Orderable Part Numbers for Independent MCU and Main PDN System

(1) TI recommends having 15% margin between the maximum expected load current and the maximum current allowed per each PMIC output rail.

Note: PDN-0C is recommended for all new designs and designs needing the additional functional safety coverage provided afforded by the GPIO optimizations found in PDN-0C. This document describes PDN-0B.
