FEATURES

DESCRIPTION

• 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 V

(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 V

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
