BTS 6142D is a PROFET series Smart High-Side Power Switch with one channel and 12 mΩ resistance, designed for automotive applications.
The BTS 6142D is a one‑channel smart high‑side power switch in a PG‑TO252‑5‑11 package, offering integrated protection features such as reverse polarity, overload, and thermal shutdown. It is designed for automotive 12 V grounded loads and can replace electromechanical relays, fuses, and discrete circuits.
The datasheet details the block diagram, pin assignments, electrical characteristics, protective and diagnostic functions, and application guidelines. It also lists maximum ratings, package dimensions, and revision history for reference by designers and engineers.
| Operating voltage | 5.5 – 24 V |
|---|---|
| Over‑voltage protection voltage | 39 V |
| On‑State resistance | 12 mΩ |
| Nominal load current | 7 A |
| Current limitation | 50 A |
| Stand‑by current (with load) | 6 A |
| Package type | PG‑TO252‑5‑11 |
It provides reverse battery protection, short‑circuit protection, overload protection, multi‑step current limitation, thermal shutdown, over‑voltage protection, loss of ground protection, loss of Vbb protection, and ESD protection.
The sense output pin delivers a current proportional to the load current and indicates fault conditions such as overload, over‑temperature, or short‑circuit.
The device is supplied in a PG‑TO252‑5‑11 surface‑mount package.
