The Texas Instruments TPS3808G18DBVT is a single-channel microprocessor supervisory circuit designed to monitor 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 low. This device features a nominal operating voltage of 1.67V and an active low reset.
Key electrical characteristics include a very low quiescent current of 2.4 µA typical and high threshold accuracy of 0.5% typical. The reset timeout is adjustable, with a power-on reset generator offering delay times from 1.25 ms to 10 s. It monitors system voltages ranging from 0.4 V to 5 V.
The TPS3808G18DBVT operates within a temperature range of -40°C to 125°C. It is supplied in a compact SOT-23-6 package, suitable for surface mount applications. The output type is open drain or open collector, and it monitors a single voltage.
This supervisory circuit is ideal for applications requiring reliable power-on reset and voltage monitoring functions, ensuring system stability during power fluctuations.
