DESCRIPTION  
TPS3803−01, TPS3803G15, TPS3805  
The TPS3803 and TPS3805 families of supervisory  
circuits provide circuit initialization and timing supervision,  
primarily for DSPs and processor-based systems.

The TPS3803G15 device has a fixed-sense threshold  
RESET

VDD  
voltage V set by an internal voltage divider, whereas the  
IT  
TPS3803−01 has an adjustable SENSE input that can be  
configured by two external resistors. In addition to the fixed  
sense threshold monitored at VDD, the TPS3805 devices  
provide a second adjustable SENSE input. RESET is  
asserted in case any of the two voltages drops below VIT.

Typical Operating Circuit  
1.6 V  
3.3 V  
During power on, RESET is asserted when supply voltage  
V
becomes higher than 0.8 V. Thereafter, the  
DD  
DVDD  
CVDD  
supervisory circuit monitors VDD (and/or SENSE) and  
keeps RESET active as long as VDD or SENSE remains  
below the threshold voltage VIT. As soon as VDD (SENSE)

rises above the threshold voltage V , RESET is

deasserted again. The product spectrum is designed for  
1.5 V, 3.3 V, and adjustable supply voltages. The devices  
are available in a 5-pin SC-70 package. The TPS3803 and  
TPS3805 devices are characterized for operation over a  
temperature range of −40°C to +85°C.
