ACE301A

Ultra-Small High-Precision Low Voltage Detector

VER 1.1

Function Description

When a voltage higher than the release voltage (+VDET) is applied to the voltage input pin (VDD), the

voltage 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 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.
