PRODUCTION DATA.
When the cathode/output voltage or current of ATL431LI is not being fed back to the reference/input pin in any form, this device is operating in open loop. With proper cathode current (Ika) applied to this device, ATL431LI will have the characteristics shown in SLVA987. With such high gain in this configuration, ATL431LI is typically used as a voltage comparator. The integrated voltage reference makes the ATL431LI a flexible device for monitoring a signal for undervoltage and overvoltage detection.
