The Texas Instruments TPS3809I50QDBVRQ1 is a 3-pin voltage supervisor IC designed for circuit initialization and timing supervision, primarily for DSPs and processor-based systems. It features an active-low, push-pull reset output and monitors a single supply voltage.
Key electrical specifications include a nominal supply voltage of 4.55V and a minimum reset timeout of 120ms, with a typical timeout of 200ms. The device operates within a temperature range of -40°C to 125°C (TA).
This supervisor IC is qualified for automotive applications and meets AEC-Q100 standards. It comes in a compact SOT-23-3 (TO-236-3, SC-59) surface-mount package, making it suitable for space-constrained designs. The typical supply current is a low 9µA.
It is pin-for-pin compatible with the MAX809 and offers features like a precision supply voltage monitor and a power-on reset generator. The reset is asserted when the supply voltage rises above 1.1V and remains active as long as the voltage is below the threshold.
