TPS3511, TPS3510 Datasheet - Texas Instruments

TPS3511 PC Power Supply Supervisors

The TPS3510/1 is designed to minimize external components of personal-computer switching power supply systems. It provides protection circuits, power good indicator, fault protection output (FPO) and PSON control. Overvoltage protection (OVP) monitors 3.3 V, 5 V, and 12 V (12-V signal detects via VD.
