Frequently Asked Questions
What is the reset threshold voltage of the TPS3305-18DG4?
The TPS3305-18DG4 has a fixed reset threshold of 2.93V, designed to monitor a 1.8V regulated supply rail. When the monitored voltage falls below this threshold, the device asserts both the active-high and active-low reset outputs to signal a power fault condition.
What input voltage range does the TPS3305-18DG4 support?
The TPS3305-18DG4 operates over an input voltage range of 2.7V to 6V, making it compatible with standard 3.3V and 5V digital systems as well as lower-voltage embedded designs. This wide range gives designers flexibility across different power rail configurations.
What package does the TPS3305-18DG4 come in, and what are its key pin functions?
The TPS3305-18DG4 is housed in an SOIC-8 (Small Outline IC, 8-pin) package. Key pins include two sense inputs for monitoring two supply voltages, one active-high reset output, one active-low reset output, and power supply pins, enabling dual-channel supervisory functionality in a compact footprint.
Is the TPS3305-18DG4 RoHS compliant?
Yes, the TPS3305-18DG4 carries Texas Instruments' 'e4' JESD-609 code, which indicates that the device is lead-free and RoHS compliant. It is manufactured with a plastic/epoxy package body and meets environmental regulations for use in commercial and industrial applications.
