TPS3802 - Texas Instruments

TPS3802 ULTRA-SMALL SUPPLY VOLTAGE SUPERVISORS

The TPS380x family of supervisory circuits monitor supply voltages to provide circuit initialization and timing supervision, primarily for DSPs and other processor-based systems. These devices assert a push-pull RESET signal when the SENSE (adjustable version) or VDD (fixed version) drops below a preset threshold. The RESET output remains asserted for the fa.
