AEC-Q100 grade 1 — the qualification gate
It is a single-channel, high-side N-channel MOSFET switch with a 1:1 input-to-output ratio and a non-inverting On/Off interface. The output configuration is high-side, meaning the switch sits between the supply rail and the load, with the load connected to ground — the typical topology for power-domain sequencing and hot-swap in automotive ECUs.
4A output with 16 mOhm Rds(on) — load budget and thermal margin
The continuous output current rating is 4A, and the typical on-resistance is 16 mOhm. The load voltage range is 2.5V to 5.5V, and the bias supply (Vcc/Vdd) is 0.8V to 5.5V. The 2.5V floor on the load rail means this switch works with 3.3V and 5V logic supplies — common in automotive sensor modules, ADAS cameras, and infotainment head units. The separate bias input allows the switch to be controlled by a lower-voltage logic signal (e.g., 1.8V from a microcontroller GPIO) while switching a higher load voltage.
Wettable-flank WSON — AOI-friendly for automotive assembly
The package is an 8-WFDFN with exposed pad, also listed as the 8-WSON (2x2) supplier device package.
The product status is Active, meaning Texas Instruments is currently manufacturing this part with no announced last-time-buy or discontinuation. For automotive programs that require multi-year supply assurance, this removes the risk of a mid-production EOL.
