Very Small µSON (1.45 mm × 1 mm) Package  
devices (TPS389x) are family of very small  
a
Adjustable Threshold down to 500 mV  
Threshold Accuracy: 1.0% Over Temperature  
Capacitor-Adjustable Delay Time  
Low Quiescent Current: 6 µA (typ)  
External Enable Input  
supervisory circuits that monitors voltage greater than  
500 mV with a 0.25% (typical) threshold accuracy  
and offer a adjustable delay time using external  
capacitors. The TPS389x family also has a logic  
enable pin (ENABLE or ENABLE) to power on/off the  
output. With the TPS3895, for example, when the  
input voltage pin (SENSE) rises above the threshold,  
and the enable pin (ENABLE) is high, then the output

below the threshold or ENABLE is low, then  
SENSE_OUT goes low. For truth tables, see Table 2

DSPs, Microcontrollers, and Microprocessors  
Notebook and Desktop Computers  
PDAs and Handheld Products  
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 a  
typical quiescent current of 6 µA with an open-drain  
output rated at 18 V. The TPS389x is available in an  
ultra-small µSON package and is fully specified over  
the temperature range of TJ = –40°C to +125°C.
