BTS3110NHUMA1

Power Distribution Switches, Load Drivers Overview

The BTS3110NHUMA1 is a single-channel low-side smart power switch from Infineon's HITFET family, designed for automotive applications. It integrates an N-channel SIPMOS power transistor with control and protection circuitry in a PG-SOT-223-4 package. The device supports a maximum supply voltage of 42V and delivers a nominal load current of 1.4A. Key electrical parameters include a maximum on-resistance of 200 mOhms at 150°C and a short-circuit current limit of 7.5A. It operates within a junction temperature range of -40°C to +150°C and features a turn-on/turn-off time of up to 100 µs.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates diagnostic capabilities including load current monitoring and thermal shutdown protection.
• Provides robust short-circuit and over-voltage protection mechanisms for reliable operation.
• Features a latch-off classification that requires a reset cycle to restore output after fault conditions.

Power Distribution Switches, Load Drivers Applications

• Automotive lighting systems
• Solenoid and relay driver circuits
• Motor control interfaces

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix Huma1 against official Infineon documentation to confirm tape and reel packaging specifications. Ensure compatibility with surface-mount assembly processes by checking moisture sensitivity levels and reflow soldering profiles defined in the datasheet. Confirm RoHS compliance status through the manufacturer's environmental certificates prior to integration into regulated assemblies.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel low-side switch with moderate current handling is required. The 1.4A nominal rating suits smaller loads compared to higher-current variants like the BTS3134N. Consider the latch-off behavior for safety-critical designs where persistent faults must halt operation until manually reset. Evaluate thermal dissipation requirements given the 3.8W power dissipation capability in the SOT-223 package.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the Classic HITFET series, representing Infineon's established line of smart power switches. It utilizes SIPMOS technology for efficient vertical power switching. The BTS3110N variant serves as the base model for this specific tape-and-reel configuration, offering a balance between performance and cost for standard automotive distribution tasks.
