产品概述 返回TOPdJ6嘉泰姆
The CXDR75120/CXDR75121 are microprocessor (μP) supervisory
circuits used to monitor the power supplies in μP and
digital systems. They provide excellent circuit reliability
and low cost.
These circuits perform a single function: they assert a
reset signal whenever the VCC supply voltage declines
below a preset threshold, with hysteresis keeping it
asserted for time delay determined by externally programmable
time delay generator after VCC has risen
above the reset threshold.
The CXDR75121L has an open-drain output stage, while the
CXDR75120 have push-pull outputs. The GCXDR75121’s open-drain
RESET output requires a pull-up resistor that can be
connected to a voltage higher than VCC. The GCXDR75120
has an active-low RESET output, while the GCXDR75120
has an active-high RESET output. The outputs are
guaranteed to be in the correct logic state for VCC
down to 0.8V.
The CXDR75120/CXDR75121 are available in 5-pin TSOT-23-5
package.
