TPS3823A-33DBVT

TPS3823A-33DBVT Description

The TPS3823A-33DBVT from Texas Instruments is a single-channel voltage supervisor designed to monitor power supply voltages in electronic systems. Housed in a compact SOT23-5 package, this supervisor IC ensures reliable system operation by generating a reset signal when the supply voltage falls below the predefined threshold of 2.93V. With a 120ms minimum reset timeout, it provides sufficient delay for stable power-up and brownout recovery. The device features an active-low reset output, making it compatible with a wide range of microcontrollers and processors. Its ROHS3 compliance and REACH unaffected status ensure environmental and regulatory adherence, while its surface-mount design facilitates easy integration into modern PCB layouts.
