Siemens TLE 4226 G Intelligent Sixfold Low‑Side Switch Datasheet
The TLE 4226 G is a sixfold low‑side power switch IC designed for automotive and industrial applications. It features four 50 mA outputs and two 500 mA outputs, open‑collector stages with power limiting, short‑load protection, and integrated Z‑diodes for inductive loads. Control inputs are TTL‑compatible Schmitt triggers, and the device provides analog and digital status outputs for error monitoring.
The datasheet includes pin configuration, electrical characteristics, absolute maximum ratings, and package dimensions. Key parameters such as supply voltage (4.75 V–5.25 V), quiescent current (8–11 mA), load current ratings, temperature range (‑40 °C to 125 °C), and protection thresholds are specified for designers.

Questions answered in these manuals
How many outputs does the TLE 4226 G provide and what are their current ratings?
It provides six low‑side switches: four 50 mA outputs (Q1‑Q4) and two 500 mA outputs (Q5‑Q6).

What protection features are built into the TLE 4226 G?
The IC includes short‑load protection, over‑temperature monitoring, and integrated Z‑diodes on all switches.

What does the preferred‑state (PREFST) input control?
When PREFST is low, switches 1‑4 are turned on and switches 5‑6 are forced off; when PREFST is high, each switch can be controlled individually via its IN pins.

How does the device protect against overload?
Each output monitors its voltage; if the voltage exceeds 4.1 V for more than 10 µs, the output is shut down and the analog and digital status outputs indicate an error.
