Hot Swap Controllers datasheet and documents for MAX5946LETX+
Hot Swap Controllers Overview
The MAX5946LETX+ is a dual-channel hot-swap voltage controller designed for PCI Express applications. It operates within a supply voltage range of 3.3 V to 12 V and draws a typical operating current of 500 uA. The device supports an ambient operating temperature range from -40°C to +85°C and is housed in a TQFN-36 package with a maximum power dissipation of 2.105 W.
Hot Swap Controllers Feature Summary
- Dual-channel architecture for independent control of two high-side switches
- Integrated fault protection mechanisms including overvoltage, undervoltage lockout, and circuit breaker functions
Hot Swap Controllers Applications
- PCI Express hot-plug controller implementations
- Telecommunications system power distribution
- Industrial equipment backplane power management
Hot Swap Controllers Procurement Notes
Verify the specific suffix LETX against the official Analog Devices datasheet to confirm pinout and thermal pad configuration. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status as distribution channels may indicate restricted supply or discontinuation based on regional inventory updates.
Hot Swap Controllers Selection Notes
Select this component when designing systems requiring simultaneous control of two PCIe slots or independent channel monitoring. Evaluate the 36-pin TQFN package constraints for PCB layout and thermal management. Compare the 500 uA quiescent current against system power budget requirements relative to alternative single-channel controllers.
Hot Swap Controllers Part Context
This part belongs to the MAX5946 series of hot-swap controllers manufactured by Analog Devices under the Maxim Integrated brand. It serves as a specialized power management integrated circuit (PMIC) within the Controllers & Switches product category, distinct from general-purpose voltage regulators.
Hot Swap Controllers Replacement Considerations
