TPS65219 Resources Overview

The TPS65219 PMIC has multiple analog and digital resources that can be configured to power different processors, FPGAs and SoCs. Table 3-1 and Table 3-2 summarize some of the key electrical spec specification for the analog rails, the possible supply configurations and programmable features for each regulator.

TPS65219 Multi function Pins

TPS65219 has three multi-function-pins that can be configured depending on functional use. Table 3-2 shows the functions available for each of these pins as well as how these functions are configured and operated.

Note: Only one of the following pins, MODE/RESET or MODE/STBY, may be configured as MODE. If both are configured as MODE, MODE/RESET takes priority and MODE/STBY is be ignored.

Table 3-2 TPS65219 Multi-function Pins
Pin Name Pin Configuration Operation

VSEL_SD/VSEL_DDR

VSEL_SD

SD-card-IO-voltage selection

Trigger voltage change between 1.8V and register-based VLDO1 or VLDO2. Polarity is configurable.
VSEL_DDR

DDR-voltage selection

Hard-wired pull-up, pull-down, or floating. Sets VBUCK3 to 1.35V, 1.2V or register-based VBUCK3. Level-sensitive.
MODE/RESET MODE

Forces Buck converters into PWM or auto-entry in PFM-mode

Connected to SoC or hard-wired pull-up/down. Level-sensitive.
RESET

Forces a WARM or COLD reset.

Connected to SoC.

WARM reset: reset output voltages to default

COLD reset: sequence down all enabled rails and power up again

Edge-sensitive.

MODE/STBY MODE

Forces Buck converters into PWM or auto-entry in PFM-mode

Pin-status determines the switching mode of the buck converters. Assert pin low for longer than tDEGLITCH_MFP to force buck regulators into PWM-mode. I2C selection also available by writing to MODE_I2C_CTRL in MFP_1_CONFIG register.
STBY

Low power mode

Disables selected rails. Assert pin low for longer than Both MODE and STBY can be combined. Level sensitive.
