The IMP1233D supply voltage monitor is an improved, low-power
replacement for the Dallas Semiconductor DS1233D. Maximum supply
current over temperature is a low 20
μ
A, representing over 60 percent
lower power as compared to the DS1233D.
The IMP1233D issues an active LOW reset signal whenever the moni-
tored supply is out-of-tolerance. A precision reference and comparator
circuit monitor power supply (V
CC
) level. Tolerance level options are 5-,
10- and 15-percent. When an out-of-tolerance condition is detected, an
internal power-fail signal is generated which forces an active LOW reset
signal. After V
CC
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 IMP1233D is designed with a open-drain output stage and operates
over the extended industrial temperature range. Devices are available in
compact surface mount SOT-223 packages.
Other low power products in this family include the IMP1810/11/12/15/
16/17 and IMP1233M.
