DESCRIPTION
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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to GND. For reliable operation, the device should not be operated at 7 V for more than t = 1000h
continuously.
Due to the low dissipation power of this device, it is assumed that TJ = TA.
