AIM702H50B
Control Input Protection circuit state SET RESET OTT 2 4 Temperature OTT - OTHYS 1 3 5 Low side output (1) Normal operation: MOSFETs turn on and output current. (2) LVIC temperature exceeds over-temperature trip level (OTT). (3) All low-side MOSFETs turn off regardless of control input condition. (4) LVIC temperature drops to over-temperature reset level (OTT-OTHYS). (5) Normal operation: MOSFETs turn on by the next ON signal (L→H).
