Overview
The TPS3824-30DBVT is a voltage supervisor IC from Texas Instruments, designed to provide circuit initialization and timing supervision, particularly for DSP and processor-based systems. This component is part of the TPS382x family, which offers a range of features to ensure proper system reset and monitoring. During power-on, the RESET output asserts when the supply voltage exceeds 1.1 V and remains active low until the supply voltage rises above the threshold voltage. The device includes an internal timer to delay the return of the output to the inactive state, ensuring a proper system reset.
