PROFET BTS 733 L1 is a two-channel high-side power switch with features including overload protection, current limitation, short-circuit protection, thermal shutdown, etc. It is suitable for 12V DC grounded loads and can replace electromechanical relays, fuses, and discrete circuits.
The PROFET BTS 733 L1 is a smart two‑channel high‑side power switch designed for 12 V DC grounded loads such as resistive and lamp applications. It replaces electromechanical relays, fuses and discrete circuits, offering CMOS‑compatible inputs and extensive diagnostic feedback.
Key specifications include overload and over‑voltage protection, thermal shutdown, reverse‑battery protection, and ESD protection. The device provides on‑state resistance as low as 36 mΩ at 25 °C, turn‑on times of 80‑180 µs, and operates over a temperature range of –40 °C to +150 °C.
| Supply voltage (over‑voltage protection) | 43 V |
|---|---|
| Nominal load current (two parallel channels) | 6.7 – 7.3 A |
| ESD protection (HBM) | 1.0 kV |
It has two independent high‑side channels.
The over‑voltage protection activates at 43 V.
The device is rated for 1.0 kV human‑body model ESD protection.
