 ACE306A
Low Voltage Detector with Built-in Delay Circuit
Description
The ACE306A Series is a series of high-precision voltage detectors with a built-in delay time generator of
fixed time. developed using CMOS process.
The detection voltage is fixed internally, with an accuracy of ±2.0%. Internal oscillator and counter timer
can delay the release signal without external parts, delay times 210 ms Two output forms, NMOS
open-drain and CMOS output are available.

Function description
When a voltage higher than the release voltage (+VDET) is applied to the voltage input pin (VDD), the
voltage will gradually fall. When a voltage higher than the detect voltage(-VDET) is applied to VDD, output
(VOUT) will be equal to the input at VDD.Note that high impedance exists at VOUT with the N-channel open
drain configuration. If the pin is pulled up, VOUT T will be equal to the pull up voltage.
When VDD falls below -VDET, VOUT will be equal to the ground voltage (VSS) level (detect state). Note that
this also applies to N-channel open drain configurations.
When VDD falls to a level below that of the minimum operating voltage (VMIN) output will become unstable.
Because the output pin is generally pulled up with N-channel open drain configurations, output will be
equal to pull up voltage.
When VDD rises above the VSS level (excepting levels lower than minimum operating voltage), VOUT
will be equal to VSS until VDD reaches the +VDET level.
Although VDD will rise to a level higher than +VDET, VOUT maintains ground voltage level via the delay
circuit.
Following transient delay time, VDD will be output at VOUT. Note that high impedance exists with the
N-channel open drain configuration and that voltage will be dependent on pull up
