PROFET® BTS 6143 D is a smart high side power switch with reverse battery protection, short circuit protection, current limitation, overload protection, thermal shutdown protection, overvoltage protection, loss of ground protection, Vbb protection, very low standby current, fast demagnetization and electrostatic discharge (ESD) protection. It is suitable for 12V and 24V DC grounded loads power switch, can replace electromechanical relays, fuses and discrete circuits.
The Infineon PROFET® BTS 6143 D is a smart high‑side power switch designed for 12 V and 24 V DC grounded loads. It integrates a charge‑pump N‑channel MOSFET, current‑sense diagnostics, and a range of protection functions such as short‑circuit, overload, over‑voltage, loss‑of‑ground and ESD protection.
The device offers low on‑state resistance, fast demagnetisation of inductive loads, and a very low standby current. It is RoHS‑compliant, AEC‑qualified, and suitable for replacing electromechanical relays, fuses and discrete circuits in automotive, industrial and consumer applications.
| On‑state resistance (RON) | 10 mΩ (typ) |
|---|---|
| Nominal load current | 8 A |
The typical on‑state resistance is 10 mΩ.
It includes short‑circuit, overload, over‑voltage, loss‑of‑ground, loss‑of‑Vb, and ESD protection.
The turn‑on delay after inverse operation is about 1 ms.
