TPS38700 is a versatile part that can be configured for multiple configurations. The part can be ordered as a pure sequencer, pure GPIO expander, or combination sequencer & GPIO outputs. The outputs can be factory configured as push-pull or open-drain. Sequencing outputs can be assigned to ACT pin and/or SLEEP pin. These sequencing outputs can be factory configured for default values and subsequently changed via I²C on power-up before sending ACT pin high. The device also features a Built in Self-Test (BIST) function which runs automatically on power up.

TPS38700 features a precise Real Time Clock (RTC) CLK32K output with the aide of an external crystal (XTAL). It also has an RTC alarm feature and a window watchdog, all of which can be configured via I²C. The TPS38700 is capable of various I²C logic levels. A full featured Graphical User Interface (GUI) is available for download in the product folder. Contact a Texas Instruments representative for custom configured part queries.

TPS38700 can be configured to have up to twelve channels and has an emergency power down (NEM_PD) function that is activated once VDD falls below the UVLO threshold of the device. Once in the emergency power down sequence, the TPS38700 will either turn off or enter into Backup state. If a voltage on V_BBAT is present and greater than 1.85 V, then the TPS38700 will enter into Backup state and the power supply for the device will switch to V_BBAT.

The TPS38700 has been characterized from -40ºC to +125ºC.
