How OptiFlash memory technology leverages external flash to solve challenges in software-defined systems

In office buildings, factory floors and automobiles, software is replacing mechanical components and fixed electric circuits. For example, replacing a mechanical lock with a smart lock gives users operational control through an app, while the manufacturer can improve or correct lock functionality through software updates. One often-forgotten challenge with this trend, however, is the increased demand placed on memory requirements.

TPSI3100-Q1

The TPSI3100-Q1 is a fully integrated isolated switch driver, which when combined with an external power switch, forms a complete isolated solid state relay solution. With a gate drive voltage of 15.8-V with 1.5/2.5-A peak source/sink current, a large availability of power switches can be used to meet many application needs. The TPSI3100-Q1 generates its own secondary bias supply from power received on its primary side, so no isolated secondary supply bias is required. The TPSI3100-Q1 provides additional power via the nominal 5-V rail (VDDM) for use by auxiliary circuits to perform various function such as current and voltage monitoring or remote temperature detection. The TPSI3100-Q1 isolation is extremely robust with much higher reliability, lower power consumption, and increased temperature ranges than those found using traditional mechanical relays and optocouplers.

How squib and contactor drivers help improve safety and efficiency in HEV/EV battery disconnect systems

Power distribution in battery management systems (BMS) for hybrid electric vehicles (HEV) and electric vehicles (EV) delivers power to core functions of the vehicle while also providing mechanisms to safely disconnect high voltage or high current events. Two core components of the power distribution system, high voltage relays and disconnect fuses, face increasing design challenges from the growing demands of supporting higher voltages, currents, efficiency, and reliability.

OptiFlash Memory Technology

OptiFlash memory technology is a TI patented technology that enables cost effective and scalable highperformance Microcontrollers (MCU) with external flash. With traditional MCUs the ratio of Flash:SRAM typically ranges between 8:1 to perhaps even 12:1. However, with TI’s AM26x MCUs equipped with OptiFlash and large on-chip SRAM (OCSRAM) and tightly coupled memory (TCM), it is possible to implement a cost optimized system, where the OCSRAM scales efficiently with external on-PCB Flash. Below figure depicts a TI Sitara™ AM26x MCU interfacing to external flash via OptiFlash compared to a traditional MCU architecture.
