Using the TMS320C5517 Bootloader
Texas InstrumentsThis application report describes the features of the on-chip ROM for the TMS320C5517 device. Included is a description of the bootloader and how to interface with it for each of the possible boot dev
Overvoltage Protector For High-Voltage Loads
Texas InstrumentsThe TPS2400 has fixed turnon and turnoff thresholds of 3 V and 6.9 V respectively making it an ideal overvoltage protector for 3.3-V and 5-V loads that are 6.9-V tolerant. However many loads have an operating voltage that is greater than 6.9 V. To be compatible with these loads the overvoltage threshold of the protector circuit can be raised above 6.9 V using the scheme presented in this appli
Power Management in an RF5 Audio Streaming Application Using DSP/BIOS (Rev. A)
Texas InstrumentsEmbedded applications commonly run in an environment where power consumption by the DSP and its peripherals needs to be minimized. However since DSP programs also need to meet time deadlines DSP power management can be a challenge.
The example provided with this application note showcases several power management techniques you can leverage in a DSP/BIOS-enabled application. As with most softw

Using LDOs and Power Managers in Systems with Redundant Power Supplies
Texas InstrumentsFor reasons of continuity in some systems independent power sources must operate in parallel. The traditional way to connect two ore more power sources in parallel uses isolation diodes. However in situations where the associated voltage drop or the presence of voltage-feedback sensing wires makes using isolation diodes undesirable special types of low dropout voltage regulators (LDOs) and hot-
