7.1 Overview

The TPS65214 provides three step-down converters, two LDOs, two general-purpose I/Os and three multifunction pins. The system can be supplied by a single cell Li-Ion battery, two primary cells or a regulated supply. The device is characterized across a -40°C to +105°C temperature range, which makes the PMIC an excellent choice for various industrial applications.

The I2C interface provides comprehensive features for using TPS65214. The status of all rails, the GPO and the GPIO can be controlled via the interface. Voltage thresholds for the undervoltage monitoring can also be customized.

The integrated voltage supervisor monitors Buck1-3 and LDO1-2 for undervoltage. The monitor has two sensitivity settings. A power good signal is provided to report the successful ramp of the five rails and GPOs. The nRSTOUT pin is pulled low until the device enters ACTIVE state. When powering down from ACTIVE- or STBY-state, nRSTOUT is pulled low again. The nRSTOUT pin has an open-drain output. A fault-pin, nINT, notifies the SoC about faults.

Buck1 can supply up to 2A at an output voltage range of 0.6V - 3.4V. Buck2 and Buck3 step-down converters can supply up to 2A of current each at an output voltage range of 0.6V - 3.4V. The default output voltages for each converter can be adjusted through the I2C interface. All three buck-converters feature dynamic voltage scaling. The step-down converters operate in a low power mode at light load or can be forced into PWM operation for noise sensitive applications.

LDO1 can support output currents of 300mA while LDO2 supports 500mA. Both LDOs support a regulation output voltage range of 0.6V - 3.3V or load-switch operation.

The I2C-interface, IOs, GPIOs, and multi-function-pins (MFP) allow a seamless interface to a wide range of SoCs.

All configurations of the rails, for example output-voltages, sequencing, are backed up by NVM. Please refer to the Technical Reference Manual (TRM) of the chosen configuration.
