BTS840S2 Description

Short technical summary and product information.

The Infineon BTS840S2 is a smart high-side power switch designed for 12V and 24V grounded loads. It integrates N-channel MOSFETs with charge pump, ground-referenced CMOS compatible input, diagnostic feedback, and proportional load current sense. This device provides embedded protective functions including short circuit protection, overload protection, current limitation, and thermal shutdown.

 

Key electrical specifications include an operating voltage range of 5.0 to 34V. The on-state resistance is 30mΩ for a single channel and 15mΩ when two channels are paralleled. The load current (ISO) is rated at 12A for a single channel and 24A for two parallel channels. Current limitation is typically 24A.

 

The BTS840S2 is suitable for various load types, including resistive, inductive, and capacitive loads. It is particularly useful for loads with high inrush currents, such as lamps. The device can replace electromechanical relays, fuses, and discrete circuits, offering advanced protection and diagnostic capabilities.

 

Packaged in a P-DSO-20-12 (Power SO 20) surface-mount package, this switch is designed for efficient heat dissipation. Its features make it a versatile solution for automotive and industrial applications requiring robust power switching and protection.
