The TLE 4211 is a double low-side switch from Texas Instruments with 2 x 2 A current capability, built-in overtemperature protection and short circuit protection, and can be controlled via TTL signals.
The TLE 4211 is an intelligent double low‑side switch IC designed for automotive electronics. It provides two 2 A low‑side switches with integrated Z‑diodes for clamp protection, overtemperature shutdown, reverse polarity protection, and status monitoring for overload, open‑load, shorted‑load, and overvoltage conditions.
The document includes pin definitions, a block diagram, circuit description, absolute maximum ratings, and characteristic curves. It specifies supply voltage limits, temperature ranges, and typical performance parameters for designers integrating the device into their circuits.
