Hot-selling and scarce TPS3705-30DR Processor Supervisory Circuits With Power-Fail SOP8 spot stock

Product Descriptions

The  TPS370x-xx  family  of  microprocessor  supplyvoltage  supervisors  provide  circuit  initialization  and timing supervision, primarily for DSP and processorbased systems.

During power-on, RESET is asserted when the supply voltage V _DD  becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors V DD and keeps RESET  active  as  long  as  V _DD   remains  below  the threshold voltage VIT+. When the supply voltage drops below the threshold voltage VIT–, the output becomes active   (low)   again.   No   external   components   are required. All the devices of this family have a fixedsense threshold voltage VIT– set by an internal voltage divider.

The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available in  either  8-pin  MSOP  or  standard  SOIC  packages. The   TPS370x-xx   devices   are   characterized   for operation over a temperature range of −40°C to 85°C.
