Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community TPS389 SBVS172B – JULY 2011 – REVISED APRIL 2015 TPS389x Single-Channel, Adjustable Voltage Monitor in Ultra-Small Package.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS3895, TPS3896, TPS3897, and TPS3898 devices (TPS389x) are a family of very small supervisory circuits that monitor voltages greater than 500 mV with a 0.25% (typical) threshold accuracy and offer adjustable delay time using external capacitors.

The TPS389x family also has a logic enable pin (ENABLE or ENABLE) to power on and off the output.

With the TPS3895, for example, when the input voltage pin (SENSE) rises above the threshold, and the ENABLE pin is high, then the output pin (SENSE_OUT) goes high after the capacitoradjustable delay time.
