Description
This IC facilitates complicated power-on and power-monitoring resets of microcomputers that require the 3.3-V and
1.8-V dual power supplies. It also facilitates change of delay time of reset signal by externally setting resistance and
capacity for delay time. By employing complementary open-drain output, desired output such as open-drain output and
CMOS output can be obtained.
Functions
 3.3-V detection voltage
 Accuracy of 3.3-V detection voltage
 Hysteresis of 3.3-V detection voltage
 Open-drain/CMOS output
 1.8-V PMOS drive output
 Ultra-small SSOP-8 package
: 2.7 V
: 1.0%
: 5% Typ.
