The TPS3808G50DBVR from Texas Instruments is a single-channel supervisory circuit that monitors system voltages. It asserts an open-drain RESET signal when the sense voltage drops below a preset threshold or when the manual reset (MR) pin is pulled low. The RESET output remains low for a user-adjustable delay time after the sense voltage and MR return above their respective thresholds.
Key electrical specifications include a nominal operating voltage of 4.65V and a monitored voltage range from 0.4V to 5V. It offers a very low quiescent current of 2.4μA typical and high threshold accuracy of 0.5% typical. The reset timeout is adjustable, ranging from 1.25 ms to 10 s.
This supervisory circuit is housed in a compact SOT-23-6 package, suitable for surface mount applications. It operates within a temperature range of -40°C to 125°C (TJ). The TPS3808G50DBVR is designed for applications requiring reliable power-on reset generation and system voltage monitoring.
Environmental compliance includes RoHS3 compliance and MSL Level 1 rating. The device is supplied in a small tape and reel (T&R) package.
