PS10NG-G

Power Supply Controllers, Monitors Overview

The PS10NG-G is a quad power supply sequencer manufactured by Microchip Technology, designed for monitoring and controlling multiple voltage rails in complex electronic systems. Housed in a compact SOIC-14 surface-mount package, this component provides precise sequencing logic to ensure safe power-up and power-down sequences. It features an open-drain output configuration suitable for interfacing with various control circuits. The device operates within a wide temperature range of -40°C to +85°C, ensuring reliability in demanding environments. A key specification includes a reset delay time of 200 ms, which allows sufficient time for voltages to stabilize before asserting the reset signal. The minimum operating threshold voltage is specified at 1.22 V, enabling compatibility with low-voltage digital logic families commonly found in modern embedded applications.

Power Supply Controllers, Monitors Feature Summary

• Monitors four independent input channels to manage sequential power transitions
• Provides open-drain outputs for flexible interface integration with downstream logic
• Ensures stable system initialization through a fixed 200 ms reset delay period

Power Supply Controllers, Monitors Applications

• Multi-rail power management in industrial control systems
• Voltage sequencing for embedded processor boards
• Power integrity monitoring in telecommunications equipment
• System reset generation in automotive electronics

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status as per manufacturer documentation. Confirm that the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the 1.22 V threshold aligns with your lowest monitored rail voltage. Check for any recent product change notifications regarding pinout or electrical characteristics. Validate that the 200 ms delay meets your system startup timing constraints.

Power Supply Controllers, Monitors Selection Notes

Choose the PS10NG-G when a dedicated hardware solution for four-channel power sequencing is required without software overhead. Consider its open-drain output capability if level shifting or wired-OR configurations are needed. Evaluate the 200 ms delay against your total system boot time budget. Compare against alternatives if manual reset functionality or watchdog timers are necessary, as this part lacks those features. Ensure the operating temperature range covers your application's environmental extremes.

Power Supply Controllers, Monitors Part Context
