The TPS3808G18QDBVRQ1 from Texas Instruments is a low-quiescent-current programmable-delay supervisory circuit. It is designed to monitor system voltages and assert a reset signal when the voltage drops below a preset threshold or when the manual reset pin is activated.
Key electrical specifications include a nominal voltage of 1.67V, an active-low reset output, and an open-drain or open-collector output type. The reset delay time is adjustable, ranging from 1.25ms to 10 seconds, allowing for flexible system timing. This device monitors a single voltage channel and features a typical quiescent current of 2.4μA and a typical threshold accuracy of 0.5% for voltages up to 3.3V.
Packaged in a compact SOT-23-6 surface-mount package, the TPS3808G18QDBVRQ1 is suitable for space-constrained applications. It operates reliably across a wide temperature range of -40°C to 125°C. The adjustable voltage input can go down to 0.4V, providing versatility for various power supply monitoring needs.
