Hot-selling and scarce TPS3895ADRYT Single-Channel Adjustable Voltage Monitor SON spot stock

Product Descriptions

The TPS3895,  TPS3896,  TPS3897,  and TPS3898 devices (TPS389x)  are a family of   very small supervisory circuits that monitor voltages greater than500 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. When SENSE falls below the threshold or ENABLE is low, then SENSE_OUT goes low.

For TPS389xA versions, both SENSE and ENABLE have a capacitor-adjustable delay. The output asserts after  this capacitor-adjustable delay when both SENSE and  ENABLE inputs  are  good.    The TPS389xP devices have a small, 0.2-µs propagation delay from when the enable pin asserts to when the output  pin asserts,  provided SENSE is above the threshold.

All  devices operate from 1.7 V to 6.5 V and have atypical  quiescent current of 6 µA with an open-drain output rated at 18 V. The TPS389x is available in an ultra-small  USON package and is fully specified over the temperature range of T_J = –40°C to 125°C.
