PROFET® BTS 726 L1 is a high side power switch produced by Texas Instruments, which has overload protection, current limitation, short circuit protection, thermal shutdown, overvoltage protection (including load dump) and other characteristics.
The BTS 726 L1 is a Smart Two‑Channel High‑Side Power Switch designed for 12 V and 24 V DC grounded loads. It replaces electromechanical relays and offers built‑in protection functions such as over‑voltage, overload, short‑circuit, thermal shutdown, and reverse‑battery protection.
The document details the product summary, pin definitions, electrical characteristics, protection functions, diagnostic features, and package information. It includes maximum ratings, on‑state resistance, load current limits, and timing diagrams for short‑circuit and open‑load detection.
| On‑state resistance (typical) | 50 mΩ |
|---|---|
| Thermal resistance (all channels active) | 34 K/W |
The device provides two independent high‑side channels.
Typical on‑state resistance is about 50 mΩ per channel.
