NCV8406ASTT1G

Product Overview

The NCV8406ASTT1G from onsemi is a surface-mount low-side N-channel power switch/driver with a 1:1 input-to-output ratio and one output. It supports a 60 V maximum load voltage and 7 A maximum output current, with 185 mΩ typical on-resistance. The On/Off, non-inverting interface includes fixed current limiting, over-temperature protection, over-voltage protection, and auto restart. It is automotive-grade AEC-Q100 qualified and rated for -40°C to 150°C junction temperature.

Key Features

• Low-side N-channel switching with a 1:1 ratio and one output.
• Handles 7 A maximum output current at 60 V maximum load voltage.
• Typical on-resistance is 185 mΩ.
• Non-inverting On/Off control; no separate supply voltage is required.
• Fixed current limiting, over-temperature protection, over-voltage protection, and auto restart.
• Automotive-grade AEC-Q100 qualified in SOT-223 (TO-261AA) package.

Applications

• Low-side switching of loads in automotive electrical subsystems
• Switching loads up to 60 V and 7 A
• Fault-tolerant switching where current limiting and auto restart are needed
• Compact surface-mount power switching using SOT-223

Design & Procurement Notes

Use this device where a single low-side N-channel switch is sufficient and load voltage remains at or below 60 V. Drive the non-inverting On/Off interface according to the required load current, and consider 185 mΩ typical on-resistance plus SOT-223 package for conduction loss and thermal design. Fixed current limiting, over-temperature protection, over-voltage protection, and auto restart support fault-tolerant switching, but verify load behavior under restart conditions.
