TPS3103K33DBVT

The Texas Instruments TPS3103K33DBVT is a supervisory circuit designed for processor-based systems, providing circuit initialization and timing supervision. It offers a precision supply voltage supervision range, with specific options including 3.3V. The device boasts a high trip-point accuracy of 0.75% and a very low supply current of typically 1.2 μA.

Key features include a reset defined with input voltages as low as 0.4V and a power-on reset generator with a delay time of 130 ms. The RESET output can be configured as either push/pull or open-drain. The operating temperature range for this component is -40°C to 125°C.

This supervisor is suitable for applications using low-power DSPs, microcontrollers, or microprocessors, as well as portable and battery-powered equipment, intelligent instruments, wireless communication systems, industrial equipment, and computers. It is supplied in a compact SOT-23-6 package, suitable for surface mounting.

The TPS3103K33DBVT monitors a single voltage supply and provides an active-low reset output. Its design ensures proper system reset by maintaining the RESET output low as long as the supply voltage remains below the threshold voltage, with a specified delay before transitioning high after the voltage surpasses the threshold.
