BTS4880RNT

Power Distribution Switches, Load Drivers Overview

The BTS4880RNT is an eight-channel high-side power switch from Infineon's Classic PROFET™ 24V family, designed for automotive load distribution. It integrates vertical N-channel power FETs with embedded protection and digital diagnostic functions. The device operates within a supply voltage range of 11 V to 45 V and supports a nominal load current of 1 A per channel when all channels are active. Key electrical parameters include a maximum short-circuit current of 3 A, a maximum total power dissipation (Ptot) of 3.3 W, and turn-on/turn-off times of up to 100 µs and 150 µs respectively. It features a minimum current limit of 3 A and is rated for an operating temperature range of -40 °C to 125 °C.
