TPS3840DL18DBVR Description

Short technical summary and product information.

The Texas Instruments TPS3840DL18DBVR is a nanopower, high-input voltage supervisor IC designed for monitoring a single power supply. It features a fixed threshold voltage of 1.8V with a typical accuracy of 1% and a maximum of 1.5%. The device includes manual reset capability and an active-low reset output, available in open-drain or open-collector topology.

 

With a wide operating voltage range from 1.5V to 10V and extremely low supply current of 300nA typical, the TPS3840DL18DBVR is suitable for low-power applications. It offers programmable reset time delay options, ranging from 50µs to 6.2s, and includes built-in hysteresis. The supervisor operates across a wide temperature range of -40°C to 125°C.

 

Packaged in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount case, this supervisor IC is ideal for space-constrained designs requiring reliable power monitoring and reset generation. Its features make it suitable for various embedded systems and portable electronics.
