MAX5977BETP+

Hot Swap Controllers Overview

The MAX5977BETP+ is a single-channel hot-swap voltage controller from Analog Devices. It operates within a supply voltage range of 1V to 16V and features a programmable current limit with a 1% accurate current-sense amplifier output. The device draws an operating supply current of 734 uA and supports power failure detection. It is housed in a TQFN-EP-20 package and functions reliably across an operating temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides latched-off output protection for fault conditions
• Integrates programmable circuit breaker, overvoltage protection (OVP), and undervoltage lockout (UVLO)
• Includes a high-accuracy current-sense amplifier for precise load monitoring

Hot Swap Controllers Applications

• General-purpose hot-swap applications
• Industrial systems requiring robust power management
• Commercial equipment needing controlled power insertion

Hot Swap Controllers Procurement Notes

Verify the specific suffix ET against official documentation to confirm package type and thermal characteristics. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the component meets RoHS compliance requirements for your target market before finalizing procurement decisions.

Hot Swap Controllers Selection Notes

Select this model when a latched fault response is required rather than auto-retry. The 1% current-sense accuracy suits precision load monitoring needs. Consider the TQFN-EP-20 package for thermal performance in compact designs. Verify that the 1V to 16V input range aligns with the system bus voltage.

Hot Swap Controllers Part Context

This component belongs to the MAX5977 family of hot-swap controllers. While the MAX5977A variant offers similar electrical specifications, it differs in fault handling behavior. The MAX5977 series is designed for protecting circuits during power insertion and removal in multi-board systems.

Hot Swap Controllers Replacement Considerations

The MAX5977AETP+ is a related part within the same family but provides different fault latch behavior. Verify functional compatibility regarding latched versus non-latched outputs before substitution.
