TPS3808G18QDBVRQ1 Information

Description

Here's a concise introduction to the TPS3808G18QDBVRQ1: The TPS3808G18QDBVRQ1 is a supervisor IC from Texas Instruments, designed for automotive applications. It's an open-drain or open-collector device with a single channel, packaged in a SOT-23-6 package. This supervisor provides a power-on reset (POR) generator with adjustable delay time from 1.25 ms to 10 seconds, making it suitable for a wide range of applications. Key features include low quiescent current consumption of 2.4 µA typical, high threshold accuracy of 0.5% typical, and a temperature range of -40°C to +125°C. The device also has a manual reset (MR) input and an open-drain RESET output. With fixed and adjustable threshold voltages available for standard voltage rails from 1.2 V to 5 V, the TPS3808G18QDBVRQ1 offers flexibility in its usage scenarios.
