What is the TLV49611TAXBXA1?
The Infineon TLV49611TAXBXA1 is a Hall effect latch designed for automotive and industrial position or speed sensing. It responds to a south pole magnetic field, switching its open-drain output when the field exceeds 2mT (trip) and releasing at -2mT (at 25°C). Supply voltage spans 3V to 26V, allowing direct connection to an unregulated battery line without a local regulator.
Key parametric decisions for the BOM
The open-drain output sinks up to 25mA — adequate for driving a logic input or a small relay coil, but not a direct solenoid load. Supply current maxes at 2.5mA, which is negligible in a vehicle electrical system.
Package and mounting — through-hole TO-92-3
The TLV49611TAXBXA1 comes in a TO-226-3 / TO-92-3 through-hole package. Three leads — supply, ground, output — with the standard 2.54mm pitch. The through-hole form suits point-to-point wiring or a PCB where a surface-mount sensor would see mechanical stress.
This part carries the Automotive, AEC-Q100 series designation. That is the qualification evidence a PPAP auditor expects — capable is not qualified. If your program requires Grade 0 with 150°C capability, this part stops at 125°C; for everything else, the AEC-Q100 sticker is clean.
Lifecycle and supply posture
No last-time-buy or obsolescence risk for a new design.
