C—see Under-Scale Current vs Temperature typical performance curve. (2) Logic High enables output (normal
operation). (3) Constant dc output to PWM (pulse-width modulated) time. (4) Maximum delay is determined by an external capacitor. Pulling the Delay Adjust Pin
low corresponds to an infinite (continuous) delay. (5) Connecting the Delay Adjust pin to +5V reduces delay time to 3
