POWER MANAGEMENT
Low Power, 5V/3.0V µP Reset
– Active LOW, Open-Drain Output
– 350ms Reset Period
The IMP1233M supply voltage monitor is an improved, low-power
replacement for the Dallas Semiconductor DS1233M. Maximum supply
current over temperature is a low 20µA, representing 60 percent lower
power as compared to the DS1233M.
The IMP1233M issues an active LOW reset signal whenever the moni-
tored supply is out-of-tolerance. A precision reference and comparator
circuit monitor power supply (VCC) level. Tolerance level options are
5- and 10-percent for a 5V power supply. The tolerance is 15-percent for
the 3.3V, IMP1233M. When an out-of-tolerance condition is detected, an
internal power-fail signal is generated which forces an active LOW reset
signal. After VCC returns to an in-tolerance condition, the reset signal
remains active for 350ms to allow the power supply and system micro-
processor to stabilize.
The IMP1233M is designed with a open-drain output stage and operates
over the extended industrial temperature range. Devices are available in
the compact surface mount SO-8 package.
Other low power products in this family include the IMP1810/11/12/15/
16/17 and IMP1233D.
