Overview
The TLV809EC26DBZR is a low-power voltage supervisor from Texas Instruments, part of the TLV80xE family. This device is designed to monitor the VDD voltage level and provide a reset signal when the voltage falls below a specified threshold. It is known for its high accuracy, low quiescent current, and wide operating temperature range, making it suitable for various applications requiring reliable voltage supervision.
The TLV809EC26DBZR is pin-to-pin compatible with other popular voltage supervisors like the MAX803/809/810 and APX803/809/810, offering enhanced features such as lower power-on-reset (VPOR) and higher accuracy.
