DESCRIPTION
2
Small, 5-Pin SC-70 (SOT-323) Package
Supply Current of 9 mA
The TPS380x family of supervisory circuits monitor
supply voltages to provide circuit initialization and
Power-On Reset Generator With Fixed Delay
timing supervision, primarily for DSPs and other
Time
processor-based systems.
–
TPS3800 = 100 ms
These devices assert a push-pull RESET signal when
–
TPS3801 = 200 ms
the SENSE (adjustable version) or VDD (fixed version)
–
TPS3802 = 400 ms
drops below a preset threshold. The RESET output
remains asserted for the factory programmed delay
Precision Supply Voltage Monitor 1.8 V, 2.5 V,
time after the SENSE or VDD return above its
2.7 V, 3 V, 3.3 V, 5 V, and Adjustable
threshold.
Manual Reset Input (Except TPS3801-01)
The TPS380x devices, except the TPS3801-01,
Temperature Range: –40°C to +85°C
incorporate a manual reset input (MR). A low level at
MR causes RESET to become active.
APPLICATIONS
The TPS380x uses a precision reference to achieve
Applications Using DSPs, Microcontrollers, or
an overall threshold accuracy of 2%—2.5%. These
Microprocessors
devices are available in a 5-pin SC-70 package,
Wireless Communication Systems
which is only about half the size of a 5-pin SOT-23
Portable/Battery-Powered Equipment
package.
Programmable Controls
The TPS380x devices are fully specified over a
Intelligent Instruments
temperature range of –40°C to +85°C.
Industrial Equipment
Notebook/Desktop Computers
Automotive Systems
