Working Principles

The LTC2901-2CGN#PBF operates by continuously monitoring the input voltages (IN1 and IN2) and comparing them to the user-programmable threshold levels (TH1 and TH2). When the input voltage falls below the corresponding threshold, the output (OUT) is pulled low. The hysteresis feature ensures that the output remains low until the input voltage rises above a higher threshold level, preventing false triggering due to noise or voltage fluctuations.
