The Texas Instruments TLV809I50DBZR is a 3-pin supply voltage supervisor IC. It provides essential circuit initialization and timing supervision, primarily for digital signal processors and processor-based systems. This device monitors a single supply voltage and asserts a reset signal when the voltage drops below a specified threshold.
Key electrical characteristics include a typical threshold voltage of 4.55V, an active-low, push-pull reset output, and a minimum reset timeout of 120ms. The device operates with a low supply current of 9µA (typical) and maintains functionality across an operating temperature range of -40°C to 85°C.
The TLV809I50DBZR is supplied in a compact SOT-23-3 (TO-236-3, SC-59) surface-mount package. This package is suitable for space-constrained applications. The supervisor circuit ensures proper system reset by delaying the return of the output to the inactive state after the supply voltage has stabilized above the threshold.
This supervisor IC is pin-for-pin compatible with the Maxim Integrated MAX809, offering a convenient alternative for existing designs. It is ideal for applications requiring reliable power-on reset generation and undervoltage monitoring.
