IN1T703/i-SCG (SOP-16)

PC SPS Secondary Supervisor with FAN control IC

sop-16

General Description

IN1T703/i is higher integrated circuit incorporates all advanced sensing function to protect from over and under voltage a two-channels protection supervisor (3.3V/5V/12V). The protections include Over Voltage Protection(OVP), Under Voltage Protection(UVP), Over Current Protection (OCP),VX.   When VS3.3/VS5/VS12 OV/UV/OC/VX fault detected, the FPOB latched(LOW),.  The function of Over Current Protection (OCP) monitors output currents through sense resistor by using smart comparator circuit is more exact and easy.  IN1T703 provide three-channels of the fault protection latch (FPOB), Power on indicated LED signal, the PSONB control and the power good control (PGO).

Feature
