S3526数据手册UTC中文资料规格书

描述 Description

UTC S3526 is used for switching power supply system. UTCS3526 provides protection functions, over-voltage protection,over-current protection, under-voltage protection and power goodsignal generating.OVP/UVP (Over-Voltage/Under-Voltage Protection) monitorstriple 12V to protect our power supply and PC, FPO goes to highwhen one of these supply voltages exceeds their normal operationvoltage range.UTC S3526 OCP (Over Current Protection) monitors IS12A,IS12B and IS12C input current sense by using smart comparatorcircuit to make the point setting through sense resistor is moreexact and easy.An additional latch protection input pin provides the flexibility fordesign protection circuit.UTC S3526 provides the fault protection latch (FPOB), thepower good output (PGO), the PSONB control and the power goodinput control pin (PGI).
