Volt Supervisor Supply 1.8V/2.5V/2.7V/3V/3.3V/5V 5-Pin SC-70 T/R
Manufacturer Part #: TPS3801-01DCKR
Alternate Part #: TPS3801-01DCKR
The TPS380x family of supervisory circuits monitor supply voltages to provide circuit initialization and timing supervision, primarily for DSPs and other processor-based systems.
These devices assert a push-pull RESET signal when the SENSE (adjustable version) or VDD (fixed version) drops below a preset threshold. The RESET output remains asserted for the factory programmed delay time after the SENSE or VDD return above its threshold.
The TPS380x devices, except the TPS3801-01, incorporate a manual reset input (MR\). A low level at MR\ causes RESET to become active.
The TPS380x uses a precision reference to achieve an overall threshold accuracy of 2%—2.5%. These devices are available in a 5-pin SC-70 package, which is only about half the size of a 5-pin SOT-23 package.
The TPS380x devices are fully specified over a temperature range of –40°C to +85°C.
