TLE 4226 G is an integrated, sixfold low-side power switch with power limiting of the 0.5 A outputs, shorted-load protection of the 50 mA switches and Z-diodes on all switches from output to ground. TLE 4226 G is particularly suitable for automotive and industrial applications.
The Siemens TLE 4226 G is an integrated sixfold low‑side power switch offering both 50 mA and 500 mA output options, built‑in short‑load protection, and Z‑diodes for inductive load clamping. It is designed for automotive and industrial applications and operates from a 5 V supply with a temperature range of –40 °C to 125 °C.
The document provides pin configurations, electrical characteristics, absolute maximum ratings, and detailed protection mechanisms, including overload, thermal, and short‑load monitoring. Package information for the P‑DSO‑24‑3 surface‑mount package is also included.
| Quad 50 mA outputs | 50 mA |
|---|---|
| Dual 500 mA outputs | 500 mA |
| Operating temperature range | –40 °C to 125 °C |
| Supply voltage range | 4.75 V–5.25 V |
| Maximum supply voltage | 10 V |
| Quiescent current (outputs OFF) | 8 mA |
| Supply current (outputs ON) | 50 mA |
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.
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.
Switches 5 and 6 can handle up to 600 mA each, while switches 1‑4 are limited to 50 mA.
If the chip temperature reaches about 155 °C, the status outputs signal over‑temperature and switches 5‑6 are shut down; they can be re‑enabled after cooling below 140 °C.
