BTS4175SGA

BTS4175SGA Description

The BTS4175SGA from Infineon Technologies is a high-side power switch designed for automotive applications, compliant with AEC-Q100 standards. Part of the Classic PROFET series, it integrates advanced protection features with robust performance in a compact 8-pin DSO (DSO-8) package. Operating within a 6V to 52V supply range, it delivers a maximum output current of 1.3A and features a low on-resistance (175mΩ typical, 350mΩ max), minimizing power dissipation. With a maximum power dissipation of 1.5W and a wide operating temperature range (-40°C to +150°C), it is engineered for harsh environments. The device supports surface-mount (SMD/SMT) assembly and is supplied in tape and reel (T/R) packaging for automated production.

BTS4175SGA Features

• High-Side Switch: Single 1-IN/1-OUT configuration with 16V max input voltage and 6A current limit for overload protection.
• Low Power Loss: Optimized on-resistance (175mΩ) ensures high efficiency, reducing thermal stress.
• Automotive-Grade: AEC-Q100 qualified, RoHS & EU RoHS compliant, and moisture-sensitive (MSL) for reliability in vehicles.
• Fast Switching: 180µs max turn-on time and 200µs max turn-off time for responsive load control.
• Integrated Protections: Built-in current limiting, overtemperature shutdown, and ESD robustness for fail-safe operation.
• Compact Footprint: 5mm x 4mm x 1.5mm DSO package saves board space in space-constrained designs.

BTS4175SGA Applications

• Automotive Systems: Ideal for body control modules (BCMs), LED lighting drivers, and seat/heater controls due to AEC-Q100 compliance.
• Industrial Load Switching: Suitable for PLC I/O modules, solenoid drivers, and low-voltage motor control.
• Power Distribution: Used in battery management systems (BMS) and 12V/24V DC power rails for robust switching.
• Consumer Electronics: Enables safe power switching in smart home devices and portable equipment.
