PROFET® BTS 734 L1 is a smart two-channel high-side power switch with overload protection, current limiting, short-circuit protection, thermal shutdown, overvoltage protection (including load dump), fast demagnetization of inductive loads, reverse battery protection, undervoltage and overvoltage shutdown with auto-restart and hysteresis, open drain diagnostic output, open load detection in ON-state, CMOS compatible input, loss of ground and loss of Vbb protection, and electrostatic discharge (ESD) protection. It is suitable for 12 V and 24 V DC grounded loads, is µC compatible, and has diagnostic feedback function, which can replace electromechanical relays, fuses and discrete circuits.
The PROFET BTS 734 L1 is a smart two‑channel high‑side power switch with overload, over‑ and undervoltage protection, short‑circuit limitation and diagnostic feedback. It is designed for 12 V and 24 V DC loads and can replace electromechanical relays, fuses and discrete circuits.
The guide provides a product summary, pin definitions, block diagrams, maximum ratings, electrical and diagnostic characteristics, truth tables, and package information, helping designers integrate the device into PCB layouts and control circuits.
| Full short‑circuit protection voltage (Vb) | 34 V |
|---|---|
| Nominal load current (two channels) | 6.7 A – 7.3 A |
| On‑state resistance (Ron) at 25 °C | 36 mΩ – 40 mΩ per channel |
| Turn‑on time (to 90 % Vout) | 80 µs – 180 µs |
| Turn‑off time (to 10 % Vout) | 80 µs – 250 µs |
The on‑state resistance is between 36 mΩ and 40 mΩ per channel.
Yes, it includes overload protection, over‑ and undervoltage protection, and short‑circuit limitation.
