IN1T709/E/G/F (SOP-16/20)

PC SPS Multi-channels supervisor with Dual Mode Fan controller and Power meter

General Description

IN1T709/E/G/F series are higher integrated circuit incorporates all advanced sensing function to protect from over and under voltage three-channels protection supervisor (T709/E/G 3.3V/5V/12V, T709F 3.3V/5V/12VA/VB).

The protections include Over Voltage Protection (OVP), Under Voltage Protection(UVP), Over Current Protection (OCP), Over temperature protection(OTP).

When VS3.3/VS5/VS12 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.

IN1T709 series provide three-channels of the fault protection latch (FPOB), the PSONB control the power good  (PGO).

Feature

  • The Over/Under Voltage Protection and 3.3V/5V/12VA/12VB
  • The Over Current Protection monitors 3.3V/5V/12VA/12VBoutput currents and related lockout
  • Fault protection output are open drain output stage
  • OVP noise immunity de-bounce
  • OCP noise immunity de-bounce
  • PSONB input signal de-bounce
  • UVP noise immunity de-bounce
  • UVP/OCP mask time
  • Power good signal
  • Auto programable 3.3V/5V/12VA/12VB OCP function
  • OCP delay time can adjustable by digital programming
  • Dual Fan control mode applications (Temperature and loading sense)
  • Power meter monitor
