STEF12H60MAPUR

Current Regulation/Management Overview

The STEF12H60MAPUR is a 60 A integrated electronic fuse optimized for monitoring output current and input voltage over 12 V DC power lines. It detects and reacts to overcurrent conditions by limiting output current to a user-defined safe value. The device features a programmable turn-on time to control inrush current and includes precise current and temperature monitor signals for system controller feedback. It supports parallel operation with current balancing, undervoltage lockout, self-diagnostic capabilities, and absolute thermal protection. The component operates within an input voltage range of 5 V to 18 V and utilizes a QFN32-5x5 package.

Current Regulation/Management Feature Summary

• Integrated current limiting and monitoring for overload protection
• Programmable turn-on time for inrush current control
• Parallel operation capability with dedicated current balancing
• Comprehensive protection including undervoltage lockout and thermal shutdown

Current Regulation/Management Applications

• Communications equipment power distribution
• Computer and peripheral power rails
• Industrial 12V DC power line protection

Current Regulation/Management Procurement Notes

Verify the specific suffix 'MA' against official STMicroelectronics documentation to confirm it denotes the latch-off fault management version rather than auto-retry. Ensure the ordering code matches the required QFN32-5x5 package configuration. Cross-reference the part number with the manufacturer's latest datasheet to validate availability and exact electrical specifications before procurement.

Current Regulation/Management Selection Notes

Select this component when designing systems requiring precise current monitoring alongside protection. The integrated MOSFET and monitor signals simplify design by reducing external components. Consider the programmable turn-on time if managing high inrush currents during startup is critical. Verify that the 12V rail operating conditions align with the specified 5V to 18V input range and thermal requirements.
