1 General Description
2 Key Features
The AS1907/AS1908/AS1909 microprocessor supervisory circuits
are ideal for monitoring the supply voltage of digital systems and
?? 3 Output Types: Push/Pull
Open Drain RESETN
RESET, Push Pull RESETN, and
microprocessors.
The devices are designed to initiate a reset if the supply voltage goes
below a predefined threshold. The duration of the reset is either 1.5,
set threshold (see Ordering Information on page 9) .
The devices are available as the standard products listed in Table 1 .
Table 1. Standard Products
?? Reset Threshold Range: 1.6 to 2.5V (~100mV increments)
?? RESET/RESETN:
- Valid to V CC = 0.7V (AS1907 and AS1908)
- Valid to V CC = 1.0V (AS1909)
?? Reset Pulse Widths: 1, 20, and 100ms
?? Supply Voltage Range: +0.7 to +3.6V

?? 3-pin SOT23 Package
The reset thresholds are factory-set between 1.6 and 2.5V in steps
of approximately 100mV (see Table 5 on page 7) .
The devices exhibit excellent reliability, and can reduce system costs
by eliminating the need for external components. The extremely low
current consumption makes the devices ideal for use in portable
applications.
The integrated reset comparator was specifically designed to ignore
fast transients on V CC .
The devices are available in a 3-pin SOT23 package.

3 Applications
The devices are ideal for use in cordless and mobile phones, MP3
players, CD and DVD players, PDAs, handheld computers, digital
cameras, hard drives, and any other application where power supply
supervisory control is required.
