IN1T707/A/B/C/D-SDG (SOP-16)
PC SPS multi-channels supervisor with fan control IC
General Description
IN1T707 is higher integrated circuit incorporates all advanced sensing function to protect from over and under voltage a two-channels protection supervisor (3.3V/5V/12VA/12VB). The protections include Over Voltage Protection(OVP), Under Voltage Protection(UVP), Over Current Protection (OCP), Over Temperature Protection(OTP). When VS3.3/VS5/VS12A/VS12B OV/UV/OC/OTP fault detected, the FPOB latched(High),. The function of Over Current Protection (OCP) monitors output currents through sense resistor by using smart comparator circuit is more exact and easy. IN1T707 provide a smart linear fan control and driver which could easy to setup fan curve.
Feature
- The Over/Under Voltage Protection and 3.3V/5V/12VA/12VB
