TPS3103E12DBVT Description

Short technical summary and product information.

The Texas Instruments TPS3103E12DBVT is a supervisory circuit designed for initializing and monitoring DSP and processor-based systems. It provides precision supply voltage supervision with a typical threshold accuracy of 0.75% and a range of available supervision voltages including 0.9V, 1.2V, 1.5V, 1.6V, 2V, and 3.3V. The device operates with a very low supply current of 1.2 μA (typical).

This supervisor asserts RESET low when the supply voltage drops below the threshold and maintains it until the voltage recovers, with a power-on reset delay time of 130 ms. It offers both push/pull or open-drain RESET outputs and is defined with input voltages as low as 0.4V. The TPS3103E12DBVT is suitable for applications using low-power DSPs, microcontrollers, or microprocessors, as well as portable and battery-powered equipment, intelligent instruments, and wireless communication systems.

The device is available in a compact SOT-23-6 package, suitable for surface mount applications. It operates over a wide temperature range of -40°C to 125°C, making it robust for various industrial and electronic environments.
