TPS389001DSER Description

Short technical summary and product information.

The Texas Instruments TPS389001DSER is a precision voltage supervisor designed for monitoring system voltages. It features a low quiescent current of 2.1 µA typical and high threshold accuracy of 1% maximum.

 

This supervisor IC offers an adjustable delay time ranging from 40 µs to 30 seconds, providing flexibility in system reset timing. It monitors a single voltage channel and provides an open-drain RESET output that asserts when the sense voltage drops below a preset threshold or when the manual reset pin is low.

 

The TPS389001DSER operates within a temperature range of -40°C to 125°C and is available in a compact 6-WSON surface-mount package measuring 1.5mm x 1.5mm. Its adjustable and selectable threshold voltages, along with precision hysteresis, make it suitable for various power management applications requiring reliable voltage supervision.
