Hot-selling and scarce TPS3809J25DBVTG4 3-Pin Supply Voltage Supervisors SOT23-3 spot stock

Product Descriptions

The TPS3809 family of supervisory circuits providescircuit  initialization  and  timing  supervision,  primarilyfor DSPs and processor-based systems . The newerTLV809E device is an alternative with the same pins,functions and electrical parameters .

During power-on, RESET is asserted when the supplyvoltage V DD  becomes higher than  1.1 V. Thereafter,the   supervisory   circuit   monitors   V DD    and   keepsRESET  active  as  long  as  V DD   remains  below  thethreshold  voltage  V IT .  An  internal  timer  delays  thereturn  of  the  output  to  the  inactive  state  (high)  toensure proper system reset . The delay time, _t d(typ)  =200 ms, starts after V DD has risen above the thresholdvoltage V IT . When the supply voltage drops below thethreshold voltage V IT , the output becomes active (low)again . No external components are required . All thedevices  of this family  have  a fixed  sense-thresholdvoltage V ITset by an internal voltage divider.

The product spectrum is designed for supply voltagesof 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are availablein   a   3-pin   SOT-23 .   The   TPS3809   devices   arecharacterized for operation over a temperature rangeof –40°C to 85°C .
